Chapter 4: Service
This chapter provides the qualified technician with the replacement and troubleshooting procedures
necessary to service the Pitco fryer.
4.1REPLACEMENT PROCEDURES
These procedures are provided to the qualified technician as a guide to removal and replacement of
various fryer components. If a test is required to verify component operation after installation, it will
be referenced.
WARNING
To prevent burns, always ensure the fryer is completely SHUT DOWN and
COOLED down before working on the fryer. Do not break any fryer gas
connections while the unit is connected to a gas supply line.
WARNING
The power supply must be disconnected before servicing or cleaning the
appliance.
4.1.1Heating Element Removal and Replacement
Replacing a heating element is a complex and time consuming procedure. Ensure that you have
tested the heating elements to determine that the element is bad and not something else.
a. Move the fryer out to gain access to the rear panels. Remove the upper small access cover
and the large lower access cover.
b. The terminal block for the heating elements is located behind the lower access plate. Tag
the connections with wire markers for easy reinstallation, and remove the wires. The
temperature probe wires are not connected through the terminal board. To disconnect the
temperature probe, remove the small access plate on top of the pivot box (plate opposite
High Limit switch). The connector for the probe is inside the pivot box. Disconnect the
probe at this connector and gently pull the wire out of the pivot box.
c. Disconnect the spring assembly from the pivot box by raising the elements and holding
them in place with a board across the tank. Do not use the element bracket to hold the
elements up.
d. Next remove the pivot box assembly by removing the screws that attach the pivot box
hinges to the fryer. The heating elements will need to be raised to gain access to the screw
heads. Support the heating element assembly before removing the screws. Removing
the hinge screws frees the heating element assembly from the fryer.
4-1
e. Once free of the fryer, set the element assembly aside. Remove the access plate on the
back of the pivot box to gain access to the heating element connectors. Disconnect the
wire for the defective element.
f.Loosen the nuts that attach the heating element to the pivot box. Slide the heating element
out of the pivot box.
g. Install the new heating element by reversing this procedure.
4.1.2Backup Thermostat Replacement - Computer Models Only
Only fryers that have computer controls have this backup thermostat. If your fryer does not have
a computer but does have a thermostat behind the door, this is a thermostat behind the door model.
That means that the knob behind the door controls the solid state temperature module behind the
fryer's control panel (front bezel). The backup thermostat includes the temperature adjustment knob,
temperature sensor inside the fryer tank, and connecting capillary tubing. The high limit controls
also has a temperature sensor in the fryer tank, so ensure you are removing the correct temperature
sensor.
CAUTION
Thermostat capillary tubing is very delicate. Be VERY CAREFUL when
working with the capillary tubing. If the tubing is kinked or broken the
thermostat is no longer usable.
a. Drain the oil from the fryer. The thermostat probe (heat sensor) is clamped to the heating
element assembly inside the tank. Unscrew and remove the two screws in the thermostat
probe clamp.
b. Remove the thermostat probe from the clamp and straighten the capillary tubing.
Unscrew the small hex nut inside the cabinet under the tank for the thermostat control.
c. Unscrew the large connector nut from the fryer tank and pull the thermostat probe and
capillary tubes through the opening.
d. Pull the knob off of the thermostat. Remove the entrance box cover to gain access to the
thermostat.
e. Mark and disconnect he wires from the thermostat terminals.
f.Remove the two screws that hold the thermostat to the inside of the entrance box. Remove
the defective thermostat control unit from the fryer.
g. Install the new thermostat in reverse order. Remember to be careful with the capillary
tubes.
4-2
h. Use pipe joint compound on the large fitting before installing to prevent oil leakage. DO
NOT use joint compound on the small nut.
i.Perform the calibration procedures detailed in section 1.5.3.
4.1.3Calibrating the Thermostat - Computer Models Only
To calibrate this thermostat the dial must be removed from the shaft. The adjustment for the
thermostat is inside the dial shaft.
a. To calibrate the thermostat you must first cause the computer to switch control to the
backup thermostat. To do this, remove the computer from the front panel and disconnect
the connector from the computer. The transfer relay will de-energize and temperature
control will shift to the backup thermostat.
b. Place the tip of a high accuracy thermometer in the shortening approximately 1" above
the temperature sensor.
c. Set the thermostat dial to 325°F and turn the fryer on.
d. Remove the thermostat dial by pulling the knob straight out. DO NOT rotate the dial.
e. Hold the outside of the shaft so it does not move. Use the tip of a small, flat tip screw
driver to scrape away the sealing compound from the adjustment screw. Turn the
adjustment screw clockwise to lower the temperature setting, and counterclockwise to
raise the temperature. One quarter turn will change the temperature approximately 25°F.
f.Turn the adjustment until the heating elements turn off at 325°F. Replace the knob and
allow the fryer to cycle 4 to 6 times. Check the temperature of the thermometer against
the thermostat dial, if it is greater than 5°F repeat the calibration procedure.
g. When the calibration is correct, remove the thermometer.
4.2TESTING CONTACTORS (RELAYS)
Contactors and relays use a control voltage to energize the electro magnet and close a set of contacts.
The control voltage is applied to a solenoid-type coil. When measuring a coil's resistance, ensure that
you have disconnected it from the fryer's electrical system. This will ensure that you are measuring
the coil's resistance and not a portion of the fryer's wiring. When measured with an OHM meter these
coils should have a very low resistance, less than 100 ohms. Measure each of the contactors that are
suspect. If any relay or contactor indicates an open circuit or high amount of resistance, replace the
coil.
4-3
4.3TESTING HEATING ELEMENTS
To check a heating element first place the OFF-ON-START switch in OFF. Check the elements by
performing the following:
a. The terminal block that connects the heating elements to the fryer is located behind the
large rear access panel. Move the fryer out and remove the access panel.
b. Using an OHM meter check continuity from one end of the element to the other. The
reading should be very low (a few ohms). If the element indicates an open circuit, replace
the element.
c. Next check from the hot side of the element to ground. It should be infinite, if it is not
replace the element.
4.4TESTING THE TEMPERATURE SETTING POTENTIOMETERS
The temperature setting potentiometer is a variable resistors. To test the potentiometer ensure that
the OFF-ON-START switch is OFF and perform the following:
a. For thermostat knobs mounted on the front of the fryer, remove the front bezel to gain
access to the back of the potentiometer. If the fryer has the thermostat knob mounted
behind the door (in the entrance box), remove the entrance box cover to gain access to
the back of the potentiometer.
b. Disconnect P10 from J10.
c. Connect an ohm-meter to pin 3 (yellow wire) and pin 1 (violet wire) and rotate the
temperature control knob. The resistance should vary from 0 to 900 ohms.
b. Connect the ohm-meter between pin 3 (yellow wire) and pin 5 (orange wire) and rotate
the knob. The resistance should again vary from 0 to 900 ohms. If the resistance is not
within the ranges specified replace the temperature setting potentiometer.
4.5TESTING THE TEMPERATURE CONTROL MODULES
The temperature control module receives 24 VAC when the OFF-ON-START switch is ON. To test
the temperature control module perform the following:
a. The temperature control module is located behind the front bezel. Remove the two screws
that hold the bezel in place and move out of the way.
b. Place the OFF-ON-START switch in ON and the Melt switch in OFF. This will apply 24
VAC to pin 1 (black wire) with pin 3 as the common (white wire) of the temperature control
module.
4-4
c. Set the temperature setting potentiometer to a temperature above the shortening's current
temperature. This will cause the temperature control module to close and pass 24 VAC to
pin 12 (gray wire) of the control module.
d. Check the temperature probe as described in section 4.6.
e. If the temperature probe test passes and there is not 24 VDC present on pin 12 of the control
module, replace the temperature control module.
4.6TESTING THE TEMPERATURE PROBE
WARNING
All power supplies must be disconnected before servicing the appliances.
Some appliances have more than one power supply. Make sure they are ALL
disconnected.
The temperature probe is a special type of resistor called a thermistor. Check the temperature probe
by performing the following:
a. Gain access to the temperature probe connection by removing the front panel. Disconnect
P10 and check the resistance of the probe at pins 2 & 4 of P10.
b. Place the OFF-ON-START switch in OFF. Use an ohm-meter to measure the resistance
across the probe. It should be about 100K ohms at room temperature (72°F, 22°C). If the
probe indicates an open or more than 200 ohms away from 100K ohms, replace the probe.
c. Re-install the probe wires and turn on the fryer. Start the fryer and raise the shortening
temperature to normal cooking temperature, approximately 350°F.
d. Unplug the temperature probe and measure the resistance again. It should read approxi-
mately 923.8 ohms ±10 ohms. If the resistance is different by more than 10 ohms, replace
the temperature probe.
4.7TESTING THE HEATING ELEMENT INTERLOCK
The heating elements are protected from accidental over heating, due to lifting them out of the oil
while unit is ON, by an interlock limit switch. The switch is located on the right side (opposite the
High Limit switch) of the heating element pivot box.
a. This test requires that you gain access to the back of the interlock switch. Remove the four
screws from the small access plate on the top, right of the pivot box. Gently move the wiring
harness to the side to expose the wiring terminal of the interlock switch.
4-5
b. Connect an ohm-meter across the switch terminals to measure the resistance across the limit
switch connection.
c. When the elements are down in the tank the interlock switch is closed and the resistance
across the switch will be zero.
d. Lift the element rack up while continuing to measure the resistance across the switch. The
rack only needs to be lifted a short distance to open the switch. A click should be heard when
the switch opens. The resistance will go up significantly when the switch opens. The
resistance will not be infinite unless the switch wires are disconnected. If there is any doubt
about the resistance, remove the wires and check the resistance. With the wires removed the
resistance will be infinite.

Chapter 5: Parts
This chapter contains listings of the components used in the different models of universal fryers.
These components are listed in two places, with the illustration and in ordered listings. The
illustrations in this chapter are provided to show relative location of components located in the fryer.
The fryer you have may not be illustrated in this chapter, but the part locations should be the same.
With each illustration there is a table of components in numerical order by illustration number. The
illustration has numbered lines pointing to components which are listed in the table.
At the end of this chapter there are alphabetical and numerical listings of all parts used in the universal
fryers. The alphabetical part list is arranged in alphabetical order according to the part name. Each
part name also has the Pitco Frialator part number. The numerical list is in Pitco Frialator part number
order. A brief description of each component is provided for each part.
