1.3.6 Testing the Temperature Probe
1. While it is still in the frypot, inspect the probe body for damage. Inspect the leads for fraying,
burning, breaks, or kinks. If the probe is bent, dented, or cracked, or if the leads are damaged, replace
the probe.
2. Determine the temperature of the cooking oil using a thermometer or pyrometer placed at the tip of
the probe.
3. Disconnect the 15-pin wiring harness from the interface board. Measure the probe resistance using
J2 pins 13 and 14.
4. Resistance should approximately equal the given probe resistance for the corresponding temperature
on the chart in Section 1.6, Page 1-23. If not, the probe has failed and must be replaced. Probes
cannot be calibrated.
NOTE: A defective probe will cause inaccurate temperature measurements. If the temperature,
as measured by the probe, varies by more than 5°F ! (2.8°C ! ) from the thermometer or pyrometer
reading, the probe should be replaced. Temperature probes cannot be calibrated.
1.4 Replacing Fryer Components
1.4.1 Replacing a Controller or Computer
1. Disconnect the fryer from the electrical power supply.
2. 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 holding the controller to the control panel frame.
4. Hinge the controller down to access the 15-pin wiring harness on the back and unplug it.
5. Lift the controller up and out of the hinged tab slots.
6. Use a 5 /
16
-inch nut driver (P/N 802-0352) to remove the nut and green grounding wire from the back
of the controller.
7. If replacing the 15-pin wiring harness, do so now. Plug the new 15-pin wiring harness into the
interface board with the metal ring on the controller-end of the connector.
8. Connect the 15-pin wiring harness and the green ground wire to the new controller. When the
connector on the harness is completely engaged, the clips on either side will snap into place.
9. Re-hinge the controller by inserting the tabs on the bottom into the slots on the control frame panel.
10. Move it into the closed position against the control panel frame and replace the screws in the top
corners.
11. Insert the top tabs on the bezel into the slots on the underside of the top cap. Slide the bezel down to
engage the lower tabs in the lower slots.
