CHAPTER 1: SERVICE PROCEDURES
1.1 General
Before performing any maintenance on your Frymaster fryer, disconnect the fryer from the electrical
power supply.
When electrical wires are disconnected, it is recommended that they be marked to facilitate reassembly.
1.2 Replacing a Controller
1. Disconnect the fryer from the electrical power supply.
2. The controller bezel is held in place by tabs at the top and bottom. Slide the metal bezel up to
disengage the lower tabs. Then slide the bezel down to disengage the upper tabs.
3. Remove the two screws from the upper corners of the control panel. The control panel is hinged
at the bottom and swings open from the top.
4. Unplug the wiring harness from the connector on the back of the controller and disconnect the
grounding wire from terminal adjacent to the connector. Remove the control panel assembly by
lifting it from the hinged slots in the control panel frame.
15-Pin Connector
Ground Wire Terminal
5. Remove the controller from the control panel assembly and install the replacement controller.
Reinstall the control panel assembly by reversing Steps 1 and 2.
1.3 Replacing Component Box Components
1. Disconnect the fryer from the electrical power supply.
2. The controller bezel is held in place by tabs at the top and bottom. Slide the metal bezel up to
disengage the lower tabs. Then slide the bezel down to disengage the upper tabs.
1-1
3. Remove the two screws from the upper corners of the control panel and allow the control panel
to swing down.
4. Unplug the wiring harness from the 15-pin connector on the interface board and disconnect the
grounding wire from terminal adjacent to the 15-pin connector on the back of the controller.
Remove the control panel assembly by lifting it from the hinge slots in the control panel frame.
5. Disconnect the wiring from the component to be replaced, being sure to make a note of where
each wire was connected.
6. Dismount the component to be replaced and install the new component, being sure that any
required spacers, insulation, washers, etc. are in place.
NOTE: If more room to work is required, the control panel frame assembly may be removed by
removing the hex head screws that secure it to the fryer cabinet (see illustration below).
Removing the component box itself from the fryer is not recommended due to the difficulty
involved in disconnecting and reconnecting the oil-return valve rods, which pass through
openings in the component box.
7. Reconnect the wiring disconnected in Step 3, referring to your notes and the wiring diagrams on
the fryer door to ensure that the connections are properly made. Also, verify that no other wiring
was disconnected accidentally during the replacement process.
8. Reverse Steps 1 through 4 to complete the replacement and return the fryer to service.
1.4 Replacing a High-Limit Thermostat
1. Remove the filter pan and lid from the unit. Drain the frypot into a Shortening Disposal Unit
(SDU) or other appropriate metal container.
DANGER
DO NOT drain more than one full frypot or two split frypots into the SDU at one time.
2. Disconnect the fryer from the electrical power supply and reposition it to gain access to the rear
of the fryer.
1-2
3. Remove the four screws from both the left and right sides of the lower back panel.
4. Locate the high-limit that is being replaced and follow the two-black wires to the 12-pin
connector C-6. Note where the leads are connected prior to removing them from the connector.
Unplug the 12-pin connector C-6 and using a pin-pusher push the pins of the high-limit out of
the connector.
5. Using a wrench, carefully unscrew the high-limit thermostat to be replaced.
6. Apply Loctite™ PST 567 or equivalent sealant to the threads of the replacement and screw it
securely into the frypot.
7. Insert the leads into the 12-pin connector C-6 (see illustration below). For full-vat units, the
leads go into positions 1 and 2 of the connector and polarity does not matter.
8. Reconnect the 12-pin connecting plug C-6. Use wire ties to secure any loose wires.
9. Reinstall the back panels reposition the fryer under the exhaust hood, and reconnect it to the
electrical power supply to return the fryer to service.
1.5 Replacing a Temperature Probe
1. Remove the filter pan and lid from the unit. Drain the frypot into a Shortening Disposal Unit
(SDU) or other appropriate metal container.
DANGER
DO NOT drain more than one full frypot or two split frypots into the SDU at one time.
2. Disconnect the fryer from the electrical power supply and reposition it to gain access to the rear
of the fryer.
3. Remove the four screws from both sides of the lower back panel. Then remove the two screws
on both the left and right sides of the back of the tilt housing. Lift the tilt housing straight up to
remove from the fryer.
4. Locate the red and white wires of the temperature probe to be replaced. Note where the leads are
connected prior to removing them from the connector. Unplug the 12-pin connector C-6 and
using a pin-pusher push the pins of the temperature probe out of the connector.
1-3
5. Raise the element and remove the securing probe bracket and metal tie wraps that secure the
probe to the element (see illustration below).
6. Gently pull on the temperature probe and grommet, pulling the wires up the rear of the fryer and
through the element tube assembly.
7. Insert the replacement temperature probe (wires first) into the tube assembly ensuring that the
grommet is in place. Secure the probe to the elements using the bracket which was removed in
Step 5 and the metal tie wraps which were included in the replacement kit.
8. Route the probe wires out of the tube assembly following the element wires down the back of the
fryer through the Heyco bushings to the 12-pin connector C-6. Secure the wires to the sheathing
with wire ties.
9. Insert the temperature probe leads into the 12-pin connector C-6 (see illustration below). For
full-vat units, the red lead goes into position 3 and the white lead into position 4 of the connector.
10. Secure any loose wires with wire ties making sure that the lead wires will not interfere with the
movement of the springs. Rotate the elements up and down making sure that movement is not
restricted and that the wires are not pinched.
11. Reinstall the tilt housing and back panels, reposition the fryer under the exhaust hood, and
reconnect it to the electrical power supply to return the fryer to service.
1-4
1.6 Replacing a Heating Element
1. Perform Steps 1-3 of section 1.5, Replacing a Temperature Probe.
2. On full-vat fryers where the temperature probe is attached to the element being replaced,
disconnect the wire harness containing the probe wiring. Using a pin pusher, disconnect the
probe wires from the 12-pin connector C-6.
3. In the rear of the fryer directly behind the frypot, disconnect the 6-pin connector for the left
element (as viewed from the front of the fryer) or the 9-pin connector for the right element.
Press in on the tabs on each side of the connector while pulling outward on the free end to extend
the connector and release the element leads (see photo below). Pull the leads out of the
connector and out of the wire sleeving.
4. Raise the element to the full up position and support the elements.
5. Remove the hex head screws and nuts that secure the element to the tube assembly and pull the
element out of the frypot. NOTE: Full-vat elements consist of two dual-vat elements clamped
together. For full-vat units, remove the element clamps before removing the nuts and screws that
secure the element to the tube assembly.
6. If applicable, recover the probe bracket and probe from the element being replaced and install
them on the replacement element. Install the replacement element in the frypot, securing it with
the nuts and screws removed in Step 5 to the tube assembly. Ensure the gasket is between the
tube and element assembly.
7. Route the element leads through the element tube assembly
and into the wire sleeving to prevent chafing. Ensure that
the wire sleeving is routed back through the Heyco bushing
keeping it clear from the lift springs. Also, ensure that the
wire sleeving extends into the tube assembly to prevent the
