BIPH52/55-MPH52/55 SERIES GAS FRYERS  
CHAPTER 1: SERVICE PROCEDURES  
1.1  
Functional Description  
BIPH52/55 and MPH52/55 Series gas fryers contain a welded stainless steel frypot that is directly  
heated by a high efficiency infrared burner system requiring approximately 43% less energy than  
conventional burners to cook the same volume.  
Self-contained combustion chambers (referred to as “burners”) are fitted into rails attached to the  
sides of the frypot, one on each side. Each combustion chamber is fitted with special ceramic tiles  
that are heated by the burning of a forced air/gas mixture. The tiles transfer heat to the frypot by  
means of infrared radiation, providing much more constant and uniform heat dispersion over the  
surface of the frypot than do conventional burners. Because less heat is lost to the atmosphere in the  
process, compared to “open-burner” designs, less fuel is required to achieve and maintain a given  
frypot temperature.  
In full-vat units, gas flow to both of the burners is regulated by one electromechanical gas valve. In  
dual-vat units, each burner has its own valve. All fryers in this series are equipped with 24 VAC gas  
valve systems, and all are configured with electronic ignition.  
1.1.1 The Electronic Ignition System  
Inside the Ignition Module  
An ignition module mounted in the component box  
(located behind the control panel) is connected to an  
Out to  
ignitor assembly at the burner. The ignition module  
performs four important functions: it provides fuse  
protection for the 24-volt circuit, provides an ignition  
spark, supplies voltage to the gas valve, and proofs the  
burner flame. The module contains a 4-second time delay  
circuit and a coil that activates the gas valve. Three types  
are in use. A closed-box design is used in most fryers, but  
in some fryers built for export the module resembles an  
interface board. A single dual-spark module is used on  
current production full-vat fryers. All dual-vat fryers use  
two single-spark modules.

25 V +  
Coil

HV

Ignition Wire  
Flame Sensor  
The ignitor assembly consists of a spark plug, an  
enrichment tube, and a flame sensor.  
At start-up, the power switch is placed in the ON position, supplying approximately 12-volts DC to  
the heat-control circuitry in the controller or computer and to one side of the heat relay coils on the  
interface board. If resistance in the temperature probe indicates the temperature in the frypot is  
below 180ºF (82ºC), the current flows through a melt cycle circuit where a timer switch alternately  
closes for 6 seconds and opens for 24 seconds. If the temperature is 180ºF (82ºC) or above, the  
current flows through a heat circuit, bypassing the timer switch. In either case, ground is supplied  
to the other leg of the heat relay coils, which then close electronic switches in the 24 VAC circuit to

provide current to the ignition module. Circuitry in the ignition module sends 24 VAC to the gas  
valve via a normally closed high-limit switch (and, in fryers with built-in filtration systems, a  
normally closed drain safety switch). Simultaneously, the module causes the ignitor to spark for 4  
seconds to light the burner. A flame sensor verifies the burner ignition by measuring the flow of  
microamps through the flame. If the burner does not light (or is extinguished), current to the  
ignition module is cut, the gas valve closes, and the ignition module “locks out” until the power  
switch is turned off and then back on. A probe monitors the temperature in the frypot. When the  
programmed setpoint temperature is reached, resistance in the probe causes the heat cycle circuitry  
in the controller to cut off current flow through the heat relay. This in turn cuts off the 24 VAC to  
the ignition module, causing the gas valve to close.  
1.1.2 Interface Board  
All fryers in this series have an interface board located in the component box behind the control  
panel. The interface board provides a link between the controller/computer and the fryer’s individual  
components without requiring excessive wiring, and allows the controller to execute commands  
from one central point. This standard interface board is also used in a number of fryer types besides  
the BIPH52/55 and MPH52/55 Series. The information contained in this section applies to  
BIPH52/55 and MPH52/55 Series applications ONLY.  
K2 and K3 are double-pole-double throw (dpdt) relays that supply 24VAC to the ignition and gas  
valve circuits, as well as 120VAC to the blower motor. The relays on this board plug into sockets.  
If a relay fails, that relay can be replaced.  
LEDs (labeled D1 through D7) are arrayed around the board to assist in troubleshooting.

1.1.3 THERMOSTATS  
BIPH52/55 and MPH52/55 Series gas fryers have temperature probes located on the front centerline  
of each frypot (dual-vat frypots have two probes, one in each vat). In this type of thermostat, the  
probe resistance varies directly with the temperature. That is, as the temperature rises, so does  
resistance, at a rate of approximately 2 ohms for every 1º F. Circuitry in the controller monitors the  
probe resistance and controls burner firing when the resistance exceeds or falls below programmed  
temperatures (setpoints). The temperatures are programmed by means of a keypad on the face of the  
controller.  
BIPH52/55 and MPH52/55 Series fryers are also equipped with a high-limit thermostat. In the event  
that the fryer fails to properly control the oil temperature, the high-limit thermostat prevents the fryer  
from overheating to the flash point. The high-limit thermostat acts as a normally closed power  
switch that opens when exposed to temperatures above 425ºF to 450ºF (218ºC to 232ºC). The  
different types of thermostats have different part numbers for CE and Non-CE models, and are not  
interchangeable.

Measuring Flame Current  
When the burner flame is properly adjusted, it will produce a current between 2.5 μA and 3.5 μA.  
Flame current is measured by placing a microamp (not milliamp) meter in series with the sensing  
wire on the ignitor. This is accomplished as follows:  
1. Place the fryer power switch in the OFF position.  
2. Disconnect the sensing wire from one of the burner ignitors and connect it to the positive lead of  
the meter. Connect the negative lead of the meter to the terminal from which the sensing wire  
was removed.

17. Remove the screws in the back panel and inside the flue cap at each end that secure the flue cap  
to the fryer and lift it clear of the fryer.  
18. Disconnect the oil return line(s) from the frypot to be removed.  
19. Carefully lift the frypot from the fryer cabinet.  
20. Remove the drain valve(s), temperature probe(s), high-limit thermostat(s), and ignitor  
assemblies. Inspect each of these components carefully and install them in the replacement  
frypot if they are in serviceable condition. Use Loctite® PST56765 sealant or equivalent on  
component threads.  
NOTE: Some servicers, based upon their experience, recommend that probes and thermostats  
be replaced whenever a frypot is replaced; however, this remains the customer’s decision.  
21. Reverse steps 1-19 to reassemble fryer.  
NOTE: Care should be taken not to over-torque nuts on frypots made of 400-series stainless  
steel, as this could tear the material. One turn past hand-tight is sufficient torque.  
22. Perform steps 14 through 18 of Section 1.6.8 to ensure that there are no leaks in the burner  
insulation.  
CAUTION  
Before installing temperature probe, high-limit thermostat, and drain valve on  
replacement frypot, clean the threads and apply Loctite® PST56765 thread sealant or  
equivalent.  
1.6.11 Replacing Frypot Insulation and/or Upper Burner Rails  
NOTE: Replacing the burner rails requires completely tearing down the frypot and installing new  
frypot insulation. Refer to the frypot exploded view on page 1-21 for component identification.  
1. Remove the frypot per Section 1.6.10.  
2. Remove the burner assemblies (1).  
3. Remove insulation retainers and blanket insulation (2).  
4. Remove the upper oil zone insulation bracket and upper oil zone insulation (3).  
5. Remove the plenum (4).  
6. Remove the front lower combustion chamber insulation retainer and insulation (5), and the front  
lower combustion chamber inner insulation retainer and insulation (6). NOTE: Full-vat units  
have two-piece insulation retainer and insulation components. Dual-vat units have one-piece  
components.  
7. Remove the upper combustion chamber insulation retainer and insulation (7).

11. Remove the upper burner rails (11). NOTE: For the following steps, refer to the frypot exploded  
view on page 1-24 for component identification.  
12. Remove any residual insulation, sealant, and/or oil from the exterior of the frypot.  
13. Place the “L” shaped pieces of the combustion chamber insulation (1) in the front and rear  
corners of both upper rail-retaining slots. (See page 1-24).  
14. Using a mallet and short piece of wood, tap the corner tabs of the combustion chamber over the  
insulation to ensure a solid seal of the burner.  
15. Install the upper burner rails (2) with the heat deflectors slanting toward the rear of the frypot.  
The rails will cover the “L” shaped pieces of combustion chamber insulation previously  
installed.  
16. Place the upper inner combustion chamber insulation and insulation retainers (3) on the top two  
studs on each side of the front of the frypot and secure with ¼”-20 washer-nuts. It is normal for  
the retainers to slice off the overhanging insulation.  
17. Place the lower rear combustion chamber insulation (4) on the lower four studs at the rear of the  
frypot.  
18. Place one 1.625-inch tubular spacer (5) on each of the flue assembly (upper) studs at the rear of  
the frypot. NOTE: There are three different sizes of spacers. Verify the size to ensure the  
correct spacers are installed.  
19. Press the flue assembly (6) over the burner rails. It may be necessary to use a rubber mallet or  
screwdriver to align the components. Use four ¼”-20 washer nuts to secure the flue assembly.  
Do not tighten the retainer nuts at this point. They should be finger-tight only. NOTE:  
The flue edge will cover one to two inches of the lower insulation.  
20. Install the lower rear combustion chamber back(s) and retainer(s) (7) with the flanged edge(s)  
against the flue. Secure with ¼”-20 washer nuts. NOTE: Full-vat units have two-piece backs  
and four retainers. Dual-vat units come with one-piece backs and only two retainers.  
21. Insert the burners (9) into the rails to ensure the rail spacing and alignments are correct. The  
burner should slide freely into and out of the rails. The upper rail can be bent slightly to increase  
or decrease tension on the burner and the edges of the slot can be closed or opened slightly to  
best fit the burner frame.  
22. Carefully wrap a strip of burner insulation (8) tightly around the rear and sides of the burner  
frame (9), with the glass-tape side of the strip on the outside. Do not use duct tape or adhesive  
to secure the strip to the burner frame.  
23. Align the burner to the burner rails while maintaining tension on the insulation strip. Insert the  
burner at a slight angle and begin pushing the burner slowly into the rails until it contacts the  
rear combustion chamber. The fit should be snug, but not excessively tight.  
1-22  
Download from Www.Somanuals.com. All Manuals Search And Download.  
24. Verify that the burners are flush with the front edge of the burner rails. Remove the excess  
burner insulation by cutting with a knife or diagonal pliers. Do not try to tear the insulation!  
25. Insert the upper front insulation (10) into its retainer (11), making sure that the holes in each  
piece are aligned with one another. Install the assembly with the insulation side toward the  
frypot and secure with ¼”-20 washer-nuts. Do not over tighten.  
26. Place a washer on each of the four lower studs on the front of the frypot. Install the lower inner  
front insulation (12) with the rectangular openings toward the drain valve nipple. Install the  
lower inner front insulation retainer(s) (13). NOTE: Full-vat units have a two-piece insulation  
retainer. Dual-vat units have a one-piece retainer.  
27. If necessary, replace the sight-glasses and insulation (14).  
28. Place one washer and one 1.888-inch spacer (15) on each stud. NOTE: There are three different  
sizes of spacers. Verify the size to ensure the correct spacers are installed.  
29. Insert the front lower insulation (16) into the front lower insulation retainer(s) (17) and install  
assembly on frypot. Secure with ¼”-20 washer-nuts. If frypot uses two retainers, connect them  
together with two ¼” self-tapping screws. NOTE: Full-vat units have a two-piece insulation  
retainer and two pieces of insulation. Dual-vat units have one-piece components.  
30. Return to the rear of the frypot and fully tighten all washer-nuts.  
31. Remove and replace the plenum gaskets (18).  
32. Place a 0.938-inch spacer (19) on the plenum-mounting studs, and mount the plenum (20).  
Ensure the gaskets are clear of the burner tubes by pulling the plenum back slightly. Place a  
washer on each stud and secure plenum with ¼”-20 lock-nuts.  
33. Install the upper oil-zone insulation (21) by pressing it under the upper combustion chamber  
metalwork. Secure the insulation with the bracket (22) and ¼” self-tapping screws.  
34. Install the upper burner rail blanket insulation (23). Position any excess insulation toward the  
top of the frypot. Avoid overhang past the bottom of the upper burner rail. Overhang in this  
area will make future burner replacement more difficult.  
35. Cover the insulation with the insulation retainer (24), and secure with ¼” self-tapping screws.  
36. Reinstall probes, drain valves, high-limit thermostats, and other pipefittings using Loctite®  
PST56765 sealant or equivalent on the threads.

1.7  
Troubleshooting and Problem Isolation  
Because it is not feasible to attempt to include in this manual every conceivable problem or trouble  
condition that might be encountered, this section is intended to provide technicians with a general  
knowledge of the broad problem categories associated with this equipment, and the probable causes  
of each. With this knowledge, the technician should be able to isolate and correct any problem  
encountered.  
Problems you are likely to encounter can be grouped into six categories:  
1. Ignition failure  
2. Improper burner function  
3. Improper temperature control  
4. Computer malfunctions  
5. Filtration malfunctions  
6. Leakage  
The probable causes of each category are discussed in the following sections. A series of  
Troubleshooting Guides is also included at the end of the chapter to assist in solving some of the  
more common problems.  
1.7.1 Ignition Failure  
Ignition failure occurs when the ignition module fails to sense a flame within the 4-second time  
delay period and locks out. When this happens, the module sends 24 VAC through the interface  
board alarm circuit to the computer.  
M2000 computers display “IGNITION FAILURE.”  
The three primary reasons for ignition failure, listed in order of probability, are problems related to:  
1. Gas and/or electrical power supplies  
2. Electronic circuits  
3. Gas valve.  
PROBLEMS RELATED TO THE GAS AND/OR ELECTRICAL POWER SUPPLIES  
The main indicators of this are that an entire battery of fryers fails to light and/or there are no  
indicator lights illuminated on the fryer experiencing ignition failure. Verify that the quick  
disconnect fitting is properly connected, the fryer is plugged in with connector twisted and locked,  
the main gas supply valve is open, and the circuit breaker for the fryer electrical supply is not  
tripped.  
PROBLEMS RELATED TO THE ELECTRONIC CIRCUITS  
If gas and electrical power are being supplied to the fryer, the next most likely cause of ignition  
failure is a problem in the 24 VAC circuit. Verify that the drain valve is fully closed. The valve is  
attached to a microswitch that must be closed for power to reach the gas valve (often, although the  
1-25  
Download from Www.Somanuals.com. All Manuals Search And Download.  
valve handle appears to be in the closed position, the microswitch is still open). If the valve is fully  
closed, refer to Section 1.8.1, TROUBLESHOOTING THE 24 VAC CIRCUIT.  
Some typical causes of ignition failure in this category include a defective sensing wire in the ignitor  
assembly, a defective module, a defective ignition wire, and a defective ignitor.  
Occasionally you may encounter an ignition failure situation in which all components appear to be  
serviceable and the microamp reading is within specification, but the unit nevertheless goes into  
ignition failure during operation. The probable cause in this case is an intermittent failure of an  
ignition module. When the unit is opened up for troubleshooting, the module cools down enough to  
operate correctly; however, when the unit is again closed up and placed back into service the module  
heats up and fails.  
PROBLEMS RELATED TO THE GAS VALVE  
If the problem is not in the 24 VAC circuit, it is most likely in the gas valve, itself. Before replacing  
the gas valve, refer to Section 1.8.2 TROUBLESHOOTING THE GAS VALVE.  
1.7.2 Improper Burner Function  
With problems in this category, the burner ignites but exhibits abnormal characteristics such as  
“popping,” dark spots on the burner ceramics, fluctuating flame intensity, and flames shooting out of  
the flue.  
“Popping” indicates delayed ignition. In this condition, the main gas valve is opening but the burner  
is not immediately lighting. When ignition does take place, the excess gas “explodes” into flame,  
rather than smoothly igniting.  
The primary causes of popping are:  
• Incorrect or fluctuating gas pressure  
• Defective or incorrectly adjusted combustion air blower  
• Inadequate make-up air  
• Heat-damaged controller or ignition module  
• Cracked ignitor or broken ignition wire  
• Defective ignition module  
• Cracked burner tile (typically causes a very loud pop).  
If popping occurs only during peak operating hours, the problem may be incorrect or fluctuating gas  
pressure. Verify that the incoming gas pressure (pressure to the gas valve) is in accordance with the  
appropriate CE or Non-CE Standard found in Section 2.3 of the BIPH52/55-MPH52/55 Series Gas  
Fryer Installation and Operation Manual (part number 819-6087), and that the pressure remains  
constant throughout all hours of usage. Refer to Section 1.4, Checking the Burner Manifold Gas  
Pressure in this manual for the procedure for checking the pressure of gas supplied to the burner.  
If popping is consistent during all hours of operation, the most likely cause is an insufficient air  
supply. Check for “negative pressure” conditions in the kitchen area. If air is flowing into the  
1-26  
Download from Www.Somanuals.com. All Manuals Search And Download.  
kitchen area, this indicates that more air is being exhausted than is being replenished and the burners  
may be starved for air.  
If the fryer’s gas and air supplies are okay, the problem is most likely with one of the electrical  
components. Examine the ignition module and controller for signs of melting, distortion, and/or  
discoloration due to excessive heat build-up in the fryer (this condition usually indicates improper  
flue performance). A melted or distorted ignition module is automatically suspect and should be  
replaced; however, unless the condition causing excessive heat is corrected, the problem is likely to  
recur.  
Verify that the ignition wire is tightly connected at both ends and free of obvious signs of damage.  
Again, if damage is due to excessive heat in the fryer, that problem must also be corrected. Check  
for proper operation by disconnecting the wire from the ignitor (spark plug), inserting the tip of a  
screw driver into the terminal. With the insulated handle of the screwdriver, hold the shaft near the  
frame of the fryer as the power switch is placed in the ON position. A strong, blue spark should be  
generated for at least 4 seconds.  
DANGER  
Make sure you are holding the insulated handle of the screwdriver and not the blade.  
The sparking charge is approximately 25,000 volts.  
Examine the ignitor (spark plug) for any signs of cracking. A cracked ignitor must be replaced.  
If all other causes have been ruled out, examine the burner tiles for any signs of cracking. If  
cracking is found, the burner must be replaced.  
Fluctuating flame intensity is normally caused by either improper or fluctuating incoming gas  
pressure, but may also be the result of variations in the kitchen atmosphere. Verify incoming gas  
pressure in the same way as for “popping,” discussed in the preceding paragraphs. Variations in the  
kitchen atmosphere are usually caused by air conditioning and/or ventilation units starting and  
stopping during the day. As they start and stop, the pressure in the kitchen may change from  
positive or neutral to negative, or vice versa. They may also cause changes in airflow patterns that  
may affect flame intensity.  
Dark spots on the burner tiles are the result of an improper air/gas mixture. Adjust the combustion  
air blower to reduce the amount of air in the mixture to correct this problem  
Flames shooting out of the flue are usually an indication of negative pressure in the kitchen. Air is  
being sucked out of the burner enclosure and the flames are literally following the air. If negative  
pressure is not the cause, check for high burner manifold gas pressure in accordance with the  
procedures in Section 1.4.  
An excessively noisy burner, especially with flames visible above the flue opening, may indicate  
that the gas pressure is too high, or it may simply be that the gas valve vent tube is blocked. If the  
incoming gas pressure is correct and the vent tube is unobstructed, the gas valve regulator is  
probably defective.  
Occasionally a burner may apparently be operating correctly, but nevertheless the fryer has a slow  
recovery rate (the length of time required for the fryer to increase the oil temperature from 270ºF to  
1-27  
Download from Www.Somanuals.com. All Manuals Search And Download.  
320ºF (132ºC to 160ºC)). The primary causes of this include an over-filled frypot, a dirty or  
out-of-adjustment combustion air blower, low burner manifold pressure, and/or damaged burner  
tiles. Adding oil to the frypot during the recovery process will also cause a slow recovery rate.  
If these causes are ruled out, the probable cause is a misadjusted gas valve regulator. Refer to  
Section 1.4, Checking the Burner Manifold Gas Pressure, for the gas valve adjustment procedure.  
1.7.3 Improper Temperature Control  
Temperature control, including the melt cycle, is a function of several interrelated components, each  
of which must operate correctly. The principle component is the temperature probe. Other  
components include the interface board, the controller itself, and the ignition module.  
Improper temperature control problems can be categorized into melt cycle problems and failure to  
control at setpoint problems.  
MELT CYCLE PROBLEMS  
In fryers equipped with M2000 computers, initiation of the melt cycle is automatic. Problems may  
originate from the controller itself, the temperature probe, or a malfunctioning heat relay on the  
interface board.  
FAILURE TO CONTROL AT SETPOINT  
Problems in this category may be caused by the temperature probe, the interface board, or the  
controller.  
1.7.4 Computer Malfunctions  
RECOVERY TIME  
Recovery time – is a method of measuring a fryer’s performance. Put simply, it is the time required  
for the fryer to increase the oil temperature from 270ºF to 320ºF (132ºC to 160ºC). This range is  
used as a standard since ambient kitchen temperatures can affect the test if lower ranges are used.  
The M2000 computer performs the recovery test each time the fryer warms up. An operator can  
view the results of the test any time the fryer is above the 325ºF (163ºC) point by pressing the  
button and entering the code 1652. The test results will be displayed in the computer’s LED panel in  
minutes and seconds. The maximum acceptable recovery time for BIPH52/55-MPH52/55 Series gas  
fryers is two minutes and twenty-five seconds.

COMMON COMPUTER COMPLAINTS  
Most problems concerning computers have to do with programming them. There are two common  
complaints:  
1. Fryer constantly displays “HI.”  
Cause: Setpoint is incorrect or missing.  
Corrective Action: Check setpoint and refer to the M2000 computer manual for instructions to  
adjust the setpoint.  
2. Temperature is displayed in Celsius.  
Cause: Computer is programmed to display in Celsius.  
Corrective Action: Turn the computer off then press  
1658.  
1.7.5 Filtration Malfunctions  
The majority of filtration problems arise from operator error. One of the most common errors is  
placing the filter pad on the bottom of the filter pan rather than over the filter screen.  
Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation  
of the filter pad, including that the correct size is being used. While you are checking the filter pad,  
verify that the O-rings on the filter pan suction tube are present and in good condition. Missing or  
worn O-rings will allow the pump to suck air and decrease its efficiency.  
If the pump motor overheats, its thermal overload will trip and the motor will not start until it is  
reset. If the pump motor does not start, press the red reset switch located on the front of the motor.  
If the pump then starts, something caused the motor to overheat. It may be just that several frypots  
in a large battery of fryers were being filtered one after the other and the pump became hot. Letting  
the pump cool down for at least a half-hour is all that is required in this case. More often, the pump  
overheated for one of the following reasons:  
• Shortening that remained in the pan after previous filtering solidified in the suction tube  
recess in the bottom of the pan or the suction tube, itself. Adding hot oil to the pan and  
waiting a few minutes will usually correct this problem. A flexible wire can be used to clean  
out the suction tube and the recess in the bottom of the pan. NEVER use compressed air to  
blow solidified shortening out of the suction tube!  
• The operator attempted to filter oil that was not heated. Cold oil is thicker and causes the  
pump motor to work harder and overheat.  
If the motor hums but the pump does not rotate, there is a blockage in the pump. Incorrectly sized or  
installed paper will allow food particles and sediment to pass through the filter pan and into the  
pump. When sediment enters the pump, the gears can bind up and cause the motor to overload,  
tripping the thermal overload. Solidified shortening in the pump will also cause it to seize, with  
similar results.

A pump seized by debris or hard shortening can usually be freed by manually moving the gears with  
a screwdriver or other instrument as illustrated on the following page. Make sure power to the  
pump motor is off before trying this.  
1. Disconnect power to the filter system.

Filter pads that are installed incorrectly will also allow food particles and sediment to pass through  
and clog the suction tube recess on the bottom of the filter pan or the suction tube, itself. Particles  
large enough to block the suction tube recess or the suction tube may indicate that the crumb tray is  
not being used.

1.7.6 Leakage  
Leakage of the frypot will usually be due to improperly sealed high-limit thermostats, temperature  
probes, and drain fittings. When installed or replaced, each of these components must be sealed with  
1-30  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Loctite® PST56765 sealant or equivalent to prevent leakage. In very rare cases, a leak may develop  
along one of the welded edges of the frypot. When this occurs, the frypot must be replaced.  
If the sides or ends of the frypot are coated with oil, the most likely cause is spillage over the top of  
the frypot rather than leakage.  
The clamps on the rubber boots that hold the drain tube sections together may loosen over time as  
the tubes expand and contract with heating and cooling during use. Also, the boot itself may be  
damaged. If the section of drain tube connected to the drain valve is removed for any reason, ensure  
that its rubber and clamps are in good condition and properly fitted around the drain tube when it is  
reinstalled. Also, check to ensure that the drain tube runs downward from the drain along its whole  
length and has no low points where oil may accumulate.  
1.8  
Troubleshooting Guides  
The troubleshooting guides on the following pages are intended to assist service technicians in  
quickly isolating the probable causes of equipment malfunctions by following a logical, systematic  
process. An additional set of operator troubleshooting guides is contained in Chapter 6 of the  
BIPH52/55-MPH52/55 Series Installation and Operation Manual (P/N 819-6087). It is suggested  
that service technicians thoroughly familiarize themselves with both sets.  
1.8.1 Troubleshooting the 24 VAC Circuit  
Prior to checking for problems associated with the 24 VAC circuit, ensure that the unit is connected  
to a power supply, the drain valve is fully closed, and the controller is on and is calling for heat  
(green dot appears under heat indicator and display toggles between LOWand TEMP).  
NOTE: All voltage measurements must be made within 4 seconds of the unit calling for heat. If unit  
does not fire within 4 seconds, ignition modules will lock out and controller must be turned off, then  
on to reset.  
The following processes will assist you in troubleshooting the 24 VAC circuit and ruling it out as a  
probable cause:  
• 24 VAC is not present on the interface board J3 pin 9 (LED 5 (GV)) and, on dual units, on  
J1 pin 9 (LED 1 (GV)).  
1. If LED 3 is not continually lit, the probable causes are a failed 24 VAC transformer or failed  
wiring between transformer and interface board.  
2. If LED 3 is continually lit, check the right PWR terminal (LED 4) for 24 VAC. On dual  
units, also check the left PWR terminal (LED 2) for 24 VAC. Verify that the F2 fuse is not  
blown.  
a. If 24 VAC is not present, the probable cause is a failed interface board, blown fuse or a  
defective heat relay.  
b. If 24 VAC is present, check for 24 VAC on V1S (or V1D and V2D, if dual unit).  
1-31

i. If 24 VAC is not present, check the fuses. If they are good, the probable causes are  
failed ignition module(s) or a failed interface board. Replace the questionable  
ignition module with one known to be good to isolate the cause.  
ii. If 24 VAC is present, the probable cause is a failed interface board.  
• 24 VAC is present on interface board J3 pin 9 (LED 5 (GV)) and, on dual units, on J1 pin 9  
(LED 1 (GV)).  
1. If 24 VAC is not present across the gas valve main coil (MV terminals), probable causes are  
an open high-limit thermostat or a failed wire between the interface board and gas valve. Be  
sure to check both valves on dual units. It may also be caused by a failed drain safety switch.  
Check continuity of high-limit thermostat and drain safety switch. If both are zero, problem  
is in wiring.  
2. If 24 VAC is present across the gas valve main coil (MV terminals), the 24 VAC circuit is  
okay and the problem may be with the gas valve. Be sure to check both valves on dual units.

1.8.2 Troubleshooting the Gas Valve  
Prior to checking for problems associated with the gas valve, ensure that the unit is calling for heat.  
Also, for non-CE units, verify that the gas valve is in the ON position.  
The following processes will assist you in troubleshooting the gas valve and ruling it out as a  
probable cause:  
• If 24 VAC is not present across gas valve main coil, the probable cause is the 24 VAC circuit.  
Refer to the 24 VAC circuit troubleshooting guide.  
• If 24 VAC is present across gas valve main coil, check the incoming gas pressure and compare  
to the tables in Section 2.3 of the Installation and Operation manual.  
1. If incoming gas pressure is not correct, the probable cause is a problem with the gas supply  
to fryer.  
2. If incoming gas pressure is correct, check the outgoing gas pressure and compare it to the  
tables on Page 2-4 of the Installation and Operation manual.  
a. If outgoing gas pressure is not correct, the probable cause is an improperly adjusted or  
failed gas valve. Adjust the valve by following the procedure “Check Burner Manifold  
Pressure” in Section 1.4 of this manual.  
If the valve cannot be adjusted, replace it.  
b. If outgoing gas pressure is correct, the gas valve is okay.  
1.8.3 Troubleshooting the Temperature Probe  
CAUTION  
Disconnect the M2000 computer before testing temperature probe resistances to  
avoid invalid readings  
Prior to checking for problems associated with the temperature probe, inspect the probe body for  
damage while it is still in the frypot. Remove and replace the probe if it is bent, dented, or cracked.  
Also, inspect leads for fraying, burning, breaks, and/or kinks. If found, replace the probe.  
The following processes will assist you in troubleshooting the gas valve and ruling it out as a  
probable cause:  
Before testing the probe, determine the temperature the cooking oil using another thermometer or  
pyrometer placed at the tip of the questionable probe.  
• If resistance through J3 pins 2 and 6 (J1 pins 2 and 6 for left side of dual unit) is not  
approximately equal to that given in the Probe Resistance Chart for the corresponding  
temperature, the probe has failed and must be replaced.

• If resistance through J3 pins 2 and 6 (J1 pins 2 and 6 for left side of dual unit) is  
approximately equal to that given in the Probe Resistance Chart for the corresponding  
temperature, measure the resistance through each of the previously tested pins to ground.  
1. If resistance is not 5 mega-Ohms or greater in each pin, the probe has failed and must be  
replaced.  
2. If resistance is 5 mega-Ohms or greater in each pin, the probe is okay.

† For Dual-vat units, use 807-3365 Single Spark Ignition Module (see NOTE 1).  
NOTE 1: U.S., Canadian, Hong Kong, and Mexican units use two different modules depending upon the  
configuration of the frypot. Dual-Vat units use two 807-3365 Single-Spark Ignition Modules. Full-Vat units  
use one 807-3366 Dual-Spark Ignition Module. Also, in full-vat units, only one latch relay (Item 17) is used,  
located in the lower right socket.
