Troubleshooting
Oven Fails To Operate: No Heat
1.
If the indicator light does not illuminate, check power supply.
2.
Check indicator light for continuity. If defective, replace indicator light.
3.
Check thermostat on front. If indicator light illuminates, power is being
supplied through thermostat to dual heating elements. Turn knob from
low to high setting and return. 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. (See Replacement Parts section in this manual.)
4.
If thermostat operates satisfactorily, check continuity of heating elements
at bootom of oven. (Access through removable lower panels.) Failure of one
element will prevent oven operation on 240 volts. If operating on 120 volts,
failure of one element will cause very slow heating. If defective, remove oven
from power source and replace both elements.
Oven Operates: Overheats
1.
Check thermostat operation as in Step 3 (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 3 (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 good 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 will cause rapid failure of old
element.
