The temperature probe relays the actual shortening temperature to
the control. If it becomes disabled, "E06" will show in the display.
Also, if the temperature is out of calibration more than 10°F, or
10°C, the temperature probe should be replaced. An Ohm check can
be performed also. See chart at end of this section.
1. Remove electrical power supplied to the fryer.
To avoid electrical shock or property damage, move the
power switch to OFF and disconnect main circuit
breaker, or unplug cord at wall receptacle.
2. Drain the shortening from the frypot.
3. Remove the control panel.
4. Using a 1/2" wrench, remove the nut on the compression fitting.
5. Remove the temperature probe from the frypot.
6. Place the nut and new ferrule on the new temperature probe and
insert the temperature probe into the compression fitting until it
extends 1/2 inch (1.3 cm) into the frypot. Use the temperature
probe gauge provided in the temperature probe kit, to ensure
proper placement in frypot. See Figures 2-1 and 2-2.
7. Tighten hand tight and then a half turn with wrench.
Excess force will damage temperature probe.
8. Connect new temperature probe to PC board and replace
control panel.
9. Replace shortening, then turn power ON, and check out fryer.
