Troubleshooting
Oven Fails To Operate: No Heat
1. If the indicator light does not illuminate, check power supply.
2. Check plug at outer end of power cord and run continuity check on complete
power cord. If defective, replace cord assembly.
3. Check indicator light for continuity. See Repair Parts drawing for access
details. If defective, replace indicator light.
4. Check thermostat. If indicator light illuminates, power is being supplied
through thermostat to heating elements. Turn knob from low to high setting
and return. A definite "snap" should be heard at low temperature end and
indicator light should turn off and on with each "snap" cycle. If "snap" is not
heard and indicator light fails to operate, replace entire thermostat.
5. If thermostat operates satisfactorily, check continuity of heating elements at
bottom center of oven. Failure of one element will cause very slow heating.
Oven Operates: Overheats
1. Check thermostat operation as in Step 4 (Oven Fails to Operate: No Heat) and
Step 2 (Oven Operates: Temperature Setting Off).
Oven Operates: Temperature Setting
"OFF"
1. Check thermostat operation as in Step 4 (Oven Fails to Operate: No Heat).
2. If thermostat continues to operate satisfactorily, recalibrate per "Checking
Thermostat Calibration" section below.
Checking Thermostat Calibration:
Each thermostat is adjusted at the factory and calibrated on precision instruments
to control temperatures accurately. Adjustment or re-calibration is not needed
unless the thermostat has been mishandled in transit or changed or abused while
in service.
To check calibration:
1. Use a high grade mercury thermometer to check temperature. For griddle
control, use a disc type thermocouple. Put a couple drops of oil on griddle
surface plate and place thermocouple disc flat into the oil.
2. Turn the dial of the termostat to 300° mark.
3. Allow enough time for temperature to stabilize or until several temperature
readings are identical.
CAUTION
• When replacing heating elements, always replace both elements. Pairing
of one new element with an old element may cause rapid failure of old
element.
