MASTER JET CF SERIES ATMOSPHERIC GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.1 Functional Description
Master Jet (MJ) CF Series Atmospheric gas fryers contain a welded stainless steel frypot that is
directly heated by gas flames that are diffused evenly over its lower surface by ceramic targets.
The flames originate from orifices in a U-shaped burner manifold positioned beneath the frypot. The
orifice diameters differ for natural and propane gas as shown in the table below. For altitudes of
2000 feet and greater, contact factory for correct orifice part number.

Gas flow to the manifold is regulated by an electromechanical gas valve. MJCF Series gas fryers are
equipped with millivolt gas valves, and MJCFE Series gas fryers are equipped with 24-volt gas
valves. All models use a pilot ignition system.
Pilot Ignition System
The pilot ignition system consists of the pilot orifice, pilot hood, and a thermopile (a thermocouple is
also used in CE units per CE requirements). The pilot serves two purposes. The first is to light the
burner, the second is to heat the thermopile. In operation, the thermopile is in contact with the pilot
flame and generates millivolts. The millivolt output passes through a normally closed high-limit
switch and energizes the gas valve pilot coil, which in turn opens the pilot valve. If the pilot flame is
extinguished, voltage is lost to the gas valve pilot coil and the pilot valve closes.
24VAC Transformer
On MJCFE models, a separate 24-volt circuit,
activated by the fryer On/Off switch,
Operating Thermostat
ON/OFF Switch
Line Voltage
provides voltage through the thermostat or
controller to the gas valve main coil, which

1.1 Functional Description (cont.)
CONTROL OPTIONS
MJCF Series gas fryers may be equipped with thermostat controllers or Computer Magic III.5
computers. KJ3FC variants are equipped with user-supplied or KFC-1 computers.
MJCF fryers equipped with thermostat controls are turned on and off with the gas valve control knob
(an On/Off switch is optional). The temperature is set by means of a knob connected directly to the
frypot-mounted thermostat. MJCFE models come equipped with a rocker switch to turn the fryer on
and off. Units equipped with thermostat controllers have no interface board.
MJCFE Series with Melt-Cycle option: When the melt cycle switch is placed in the ON position, the
fryer stays in the melt cycle mode until the switch is manually placed in the OFF position, even if the
frypot is at setpoint temperature.
Fryers equipped with computers have an interface board located in the component shield behind the
control panel.
INTERFACE BOARDS
The interface board provides the link between the computer and the fryer’s components without
requiring excessive wiring, and allows the computer to execute commands from one central point.
Depending upon the configuration of the fryer, any of three boards may be used. Regardless of the
particular board installed when the fryer was built, P/N 806-3548 is the universal replacement
part (not applicable to user-supplied computers).

Every board contains one heat relay (K3), and may contain two basket lift relays (K1 and K2). As
shipped from the factory, fryers with bell-crank basket lifts will have relays K1, K2, and K3. All
other factory-original fryers will have boards with only relay K3.
NOTE: The basket lift option is not available on MJCF Series fryers. The above diagnostic
tables are not applicable to user-supplied or KFC-1 computers.
THERMOSTATS AND TEMPERATURE PROBES
MJCF Series fryers equipped with thermostat controls have an adjustable controlling (operating)
thermostat. The temperature at which the thermostat opens and closes is adjusted by changing the
setting of the thermostat with an attached knob. When new, the Fenwal controlling thermostat is
sensitive to one-degree changes in temperature.
CAUTION
Fenwal thermostats are used in a number of Frymaster products. The thermostat for
the MJCF Series is 4 inches long. Do not use 3-inch Fenwal thermostats in MJCF
Series fryers.

MASTER JET CF SERIES ATMOSPHERIC GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.1 Functional Description (cont.)
MJCFE Series fryers equipped with computers have a temperature probe. In these units, 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 1° (F or C). Circuitry in the computer 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
computer.
All MJCF Series Atmospheric gas fryers are 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 in the range of 415°F to 435°F (213°C to 224°C).
The high-limit thermostat is the same for CE and Non-CE applications. When a replacement high-
limit thermostat is ordered, ensure the kit appropriate for the valve in use is ordered.
1.2 Accessing Fryers for Servicing
DANGER
Moving a fryer filled with oil may cause spilling or splattering of hot liquid. Follow
the draining instructions in the Operator’s manual that shipped with the fryer.
1. Shut off the gas supply to the unit. Unplug the power cord(s). Disconnect the unit from the gas
supply.
2. Remove any attached restraining devices.
3. Relocate the fryer for service accessibility.
4. After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices,
and plug in the electrical cords.

1.5 Cleaning Gas Valve Vent Tube
1. Carefully unscrew the vent tube from the gas valve. NOTE: The vent tube may be straightened
for ease in removal.
2. Pass a piece of ordinary binding wire (.052 inch diameter) or equivalent through the tube to
remove any obstruction.
3. Remove the wire, and then blow through the tube to ensure it is clear.
4. Reinstall tube and bend it so that the opening is pointing downward.
1.6 Adjusting Burner Ceramic Target Spacing and Alignment
DANGER
Drain the frypot or remove the handle from the drain valve before proceeding further.
Proper spacing of the top edge of the burner ceramic targets is ¾-inch (13 mm) from the frypot side
[The rear target should be adjusted to 1-inch (25 mm) from the frypot back]. To adjust target
spacing, bend the brackets to which they are attached away or toward the frypot to the proper
distance. (A length of board of the proper thickness is useful as a gauge to verify spacing and
alignment.)
3/4-inch
1-inch
There should be about 3/4-inch spacing between the top edge of the targets
and the side of the frypot, and 1-inch between the rear target and the frypot
back.

CHAPTER 1: SERVICE PROCEDURES
1.7 Calibrating Thermostat Control
1. Fill the frypot to the lower OIL-LEVEL line with oil. If solid shortening is used, it must be
tightly packed into the frypot.
2. Light the pilot. (Refer to Installation and Operation Manual that shipped with the fryer for
detailed lighting instructions.)
3. Insert a good grade thermometer or pyrometer into the frypot, about one inch from the
thermostat.
4. Set the thermostat to 325°F (163°C).
5. Allow the fryer to heat to 325°F (163°C) and cycle on and off three times.
6. With the oil temperature at 325°F (163°C) turn the flexible shaft slowly clockwise until the
burner shuts off. (Turning the shaft counterclockwise causes the temperature to increase and the
burner to light; turning it clockwise causes the temperature to decrease and shut off.)
7. Allow the fryer to sit for a few minutes and then slowly turn the flexible shaft counterclockwise
until the burner lights.
8. Repeat steps 6 and 7 at least three times to ensure an accurate setting is obtained. The thermostat
control is calibrated if the burner lights as the oil cools to 325°F (163°C) – not when the burner
shuts off as the temperature rises.
9. Compare the reading of the pyrometer to the setting on the thermostat plate. The position of the
knob on the thermostat and the reading from the pyrometer should be within 5°F (3°C) of each
other.
10. If not, loosen the setscrew and stop screw securing the thermostat shaft extension to the flexible
shaft. Remove the extension to expose the slot in the end of the flexible shaft. Use a flat-blade
screwdriver to adjust the thermostat.
11. Once the calibration point of 325°F (163°C) is determined, allow the burner to cycle on and off
at least three times to ensure it will light at the calibrated temperature.
12. Carefully replace the thermostat shaft extension, ensuring that the stop screw is pointed straight
up. Tighten the stop screw and locking nut and the setscrew, being careful not to rotate the
flexible shaft.
CAUTION
The thermostat flexible shaft must not be rotated while installing the thermostat
shaft extension!
When handling the thermostat, do not rotate the shaft more than two turns in either
direction. Doing so will cause damage to the thermostat.

1.9 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 likely encountered can be grouped into six broad categories:
1. Pilot/Ignition failures
5. Filtration problems
6. Leakage
2. Improper burner functioning
3. Improper temperature control
4. Computer-related problems
The probable causes of each category are discussed in the following sections. Troubleshooting
charts are included at the end of the chapter to assist in identifying some of the more common
problems.
1.9.1 Pilot/Ignition Failures
There are two categories: no pilot flame and unreliable flame.
No pilot flame
1. No gas or insufficient gas supply.
2. Clogged pilot orifice.
3. Air in gas lines (usually in new installations).
4. Open or grounded high limit.
Unreliable flame
1. Loose/corroded wire connections.
2. Low or no voltage out of thermopile / thermocouple (CE units).
3. Defective gas valve.

MASTER JET CF SERIES ATMOSPHERIC GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.9.1 Pilot/Ignition Failures (cont.)
Ignition failures occur when the 24VAC power supply to the gas valve is interrupted, when the gas
supply is interrupted, or when the pilot flame is extinguished.
There are three primary reasons for ignition failure, listed in order of probability:
1. Problems related to the gas and/or electrical power supplies.
2. Problems related to the electronic circuits.
3. Problems related to the 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 hose is properly connected, the fryer is plugged in, 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 of the pilot system. If the fryer is equipped with a Filter
Magic II filtration system, first 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 valve handle
appears to be in the closed position, the microswitch is still open.) If the valve is fully closed, or the
fryer does not have a filtration system, refer to the troubleshooting tables in this chapter.
PROBLEMS RELATED TO THE GAS VALVE
If the problem is not in the 24 VAC circuit of the pilot system, it is most likely in the gas valve itself,
but before replacing the gas valve refer to the troubleshooting tables in this chapter.

MASTER JET CF SERIES ATMOSPHERIC GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.9.2 Improper Burner Functioning
The burner ignites but exhibits abnormal characteristics such as "popping", incomplete lighting of
the burner, fluctuating flame intensity, and flames "rolling" out of the fryer.
"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
• Misdirected or weak pilot flame
• Burner deflector targets out of alignment or missing
• Clogged burner orifices
• Inadequate make-up air
• Clogged vent tube, causing incorrect gas pressure
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 standards found in the tables on Pages 1-5 and 1-6, and that the pressure
remains constant throughout all hours of usage. Refer to Section 1.3 for the procedure for checking
the burner gas pressure.
If popping is consistent during all hours of operation, verify that the pilot is properly positioned
above the burner orifice and that the pilot pressure is correct. Correct pilot pressure is indicated by a
flame 1 to 1-½" (25 to 38 mm) long. Refer to Section 1.4 for the pilot flame adjustment procedure.
Clogged burner orifices, especially those near the pilot, are also likely causes of delayed ignition.
Clogged orifices are indicated by no flame, flames that are orange-colored, and flames that shoot out
at an angle from the rest.
Another cause of popping is an insufficient air supply or drafts that are blowing the pilot flame away
from the burner. Check for "negative pressure" conditions in the kitchen area. If when the door is
opened to the kitchen and a rush of incoming air is felt, this indicates that more air is being
exhausted than is being replenished and the burners may have insufficient combustion air.
If the fryer’s gas and air supplies are okay, the problem most likely is with one of the electrical
components. Examine the computer for signs of melting/distortion and/or discoloration due to
excessive heat buildup in the fryer. (This condition usually indicates improper flue performance.).
A discolored or distorted computer should be replaced immediately. To prevent recurring problems,
correct the condition immediately.
The burner lighting on one side only may be caused by a missing or misaligned rear deflector target
or improper burner manifold pressure. Clogged burner orifices are usually the cause of gaps in
burner firing.

MASTER JET CF SERIES ATMOSPHERIC GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.9.2 Improper Burner Functioning (cont.)
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 unit air-exchange. As
the systems 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.
Flames "rolling" out of the fryer are usually an indication of negative pressure in the kitchen. Air
is being sucked out of the fryer 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 1.3. An obstructed flue, which prevents the fryer from properly exhausting,
may also be the cause.
An excessively noisy burner, especially with flames visible above the flue opening, may indicate
that the burner gas pressure is too high, or it may simply be that the gas valve vent tube is blocked.
If the 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 the fryer has a slow recovery rate.
[The recovery rate is the length of time required for the fryer to increase the oil temperature from
250°F to 300°F (121°C to 149°C)]. Low burner manifold pressure and/or misaligned or missing
deflector targets are usually the main causes. If both of these causes are ruled out, the probable
cause is a gas valve regulator that is out of adjustment. See Section 1.3 to adjust regulator.
1.9.3 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 thermostat (in thermostat control
units) or the temperature probe (in fryers equipped with computers). Depending upon the specific
configuration of the fryer, other components may include the interface board and the computer.
Improper temperature control problems can be categorized into melt cycle problems and failure to
control at setpoint problems.

1.9.3 Improper Temperature Control (cont.)
MELT CYCLE PROBLEMS
NOTE: In early 1999, PC board melt cycle timers replaced melt-cycle timer motors in new fryers.
See Section 1.8.8 for retrofit information.
In fryers equipped with thermostat controls, the melt cycle is controlled by a mechanical timer or a
PC board. Three components that that can fail are the melt-cycle timer, the melt-cycle timer
microswitch or the control panel melt cycle On/Off switch. Isolate the defect and replace defective
component.
In fryers equipped with computers, the problem may be with the computer itself, the temperature
probe, or a malfunctioning heat relay on the interface board. Refer to the troubleshooting tables in
this chapter.
FAILURE TO CONTROL AT SETPOINT
In fryers equipped with thermostat controls, the problem will be with the thermostat itself. Possible
causes are that the thermostat is out of calibration, the knob or flexible shaft is loose on the
thermostat shaft, a thermostat wire is disconnected or broken, or the thermostat is defective. Refer to
Section 1.7 for instructions on calibrating the thermostat.
In fryers equipped with other types of controls, the problem may be with the temperature probe, the
interface board, or the controller. Refer to the troubleshooting tables in this chapter.
1.9.4 Computer-Related Problems
Computer Magic III.5 Features
Sensitivity or "Stretch Time"
Sensitivity or stretch time is a programmable feature that increases the cook time countdown based
on variations in the oil temperature from the setpoint.
The sensitivity for each product button has 10 settings (0 through 9). A "0" sensitivity setting will
disable the feature (no change in cooking time), while a nine will provide the highest sensitivity or
most change. The correct sensitivity for any product is based on the product, its density, the setpoint
temperature, and the customer’s own requirements.

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 250°F to 300°F (121°C to 149°C). This range is used
as a standard since ambient kitchen temperatures can affect the test if lower ranges are used.
The Computer Magic III.5 performs the recovery test each day as the fryer warms up. An operator
can view the results of the test any time the fryer is above the 325°F (163°C) 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. An acceptable recovery time for the MJCF Series fryers is 3 minutes,
30 seconds.
Common Computer Complaints
Most problems concerning computers have to do with programming them. There are four common
complaints. The complaints, their causes, and corrective actions are:
1. Fryer constantly displays "
".
Cause: Setpoint incorrect or missing.
Corrective Action: Press
1 6 5 0, enter the correct setpoint using keypad, press
again, then
press
to lock in the setpoint.
2. Temperature is displayed in Celsius.
Cause: Computer is programmed to display in Celsius.
Corrective Action: Press
1 6 5 8.
3. Temperature is constantly displayed.
Cause: Computer is programmed for constant temperature display.
Corrective Action: Press
1 6 5 L.
4. Computer times down too slowly or too quickly.
Cause: Computer is compensating for oil temperature via the sensitivity setting.
Corrective Action: Reprogram sensitivity setting for each product in accordance with
programming instructions in the Frymaster Fryer Controllers User’s Manual that shipped with
the computer.

CHAPTER 1: SERVICE PROCEDURES
1.9.5 Filtration Problems
The majority of filtration problems arise from operator error. One of the most common errors is
placing the filter paper 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 paper, and the paper size. While you are checking the filter paper, verify that the O-rings
on the bottom of the filter pan, and on the male disconnect (at inside rear of filter cabinet) 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 end of the motor
nearest the operator. If the pump then starts, something caused the motor to overheat. It may be just
that several frypots were being filtered one after the other and the pump got 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 has solidified in the pan or filter lines.
• Attempt to filter unheated oil or shortening. Cold oil and shortening are thicker and cause the
pump motor to work harder and overheat.
If the motor tries to run but the pump does not, 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 causing the motor to overload, again
tripping the thermal overload. Solidified shortening in the pump will also cause it to seize, with the
same result.
A pump seized by debris or hard shortening can
usually be freed by manually moving the gears

CHAPTER 1: SERVICE PROCEDURES
1.9.5 Filtration Problems (cont.)
Incorrectly sized or installed paper will also allow food particles and sediment to pass through and
clog the suction tube on the bottom of the filter carriage. Particles large enough to block the suction
tube may indicate that the crumb tray is not installed in the pan during filtering.
Pan blockage can also occur if shortening is left in the pan and allowed to solidify. The heater strip
on the suction tube is designed to prevent solidification of residual shortening left in the tube. It will
not melt or prevent solidification of shortening in the pan.
Blockage removal can be accomplished by forcing the item out with an auger or drain snake.
Compressed air or other pressurized gases should not be used to force out the blockage.
Possible problems with the Power Shower include clogged openings, shortening solidified in the
tubes, missing clean-out plugs, and missing or worn O-rings. Cleaning the unit and replacing
missing plugs and missing or worn O-rings will correct these problems.
The electronics of the Filter Magic II are simple and straightforward. Microswitches, attached to the
oil-return valve handles of each vat and wired in parallel, provide the 24 VAC needed to activate the

CHAPTER 1: SERVICE PROCEDURES
1.9.6 Leakage
Leakage of the frypot is mostly due to improperly sealed high-limits, thermostats/temperature
probes, and drain fittings. When installed or replaced, each of these components must be sealed with
Loctite PST567 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 and/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, which hold the drain tube sections together, may loosen over time as the tubes expand
and contract with heating and cooling during use. If the section of drain tube connected to the drain
valve is removed for whatever reason, make sure that its grommet is in good condition and properly
fitted around the nipple of the drain when it is reinstalled. Also, ensure that the drain tube runs
downward from the drain along its whole length and has no low points where oil may accumulate.
1.9.7 Troubleshooting, Millivolt Frying Systems
How the Millivolt Circuit Works
The voltage output of a thermopile powers the coil of a millivolt gas valve. This output is measured
in millivolts or thousandths of one volt.
The high-limit thermostat acts as a safety switch. It will de-energize the gas valve when the oil in the
fryer’s frypot climbs to 425°F to 450°F.
An operating thermostat controls the main coil actuation and acts as the burner control.

When troubleshooting millivolt systems, always check these areas before performing diagnostic
checks on either the Robertshaw or Honeywell systems:
A. Inspect all wires and component leads for damage (heat, oil, moisture, etc.). On capillary
tube-type thermostats, check for resistance on the thermostat lead wires. Wire nuts and other
connectors cannot be present in a millivolt circuit as they can cause resistance. If resistance
is found, solder the connectors to the wires or replace the wires.
B. Clean and verify that all wire connections and gas valve terminal connections are tight.
C. Check the length of the pilot flame (it should be about 1½-inches (38mm) long) and verify
that it contacts the top one third of the thermopile. Clean the pilot orifice and adjust the pilot
strength if needed.
D. Measure thermopile output with no load (i.e., with the thermopile disconnected from the gas
valve). Measurements must be made with a multimeter having a 0-1000 DC millivolt (MV)
range. Light the pilot and have someone hold the gas cock knob in the depressed position. If
the thermopile is a single lead (coaxial) type, measure from the lead’s end contact to its
screw-in threads. If the thermopile has two leads, measure across the end terminals. The
reading should be within the range of 500-800 millivolts. If not, replace the thermopile.
Performing diagnostic checks on Robertshaw and Honeywell Systems are described on the following
page.
