1. Verify that power is available at the outlet or junction box.
2. Verify that the circuit breaker switch on the back of the unit is turned on.
3. Verify that the power cord is not open. Check continuity with a VOM meter.
4. If none of the above steps help, call a qualified service technician or refer to the Service Manual for this

Check to verify that the high limit switch located at the rear of the unit top has not been tripped. If it has been

tripped, reset by pressing the high limit reset button at the rear of the oven.
After resetting, the cause of the high limit trip must be corrected. If the high limit switch will not reset, the high

limit switch is defective and must be replaced.

This is a safety device and must not be jumped out or removed

from the circuit.

C. To test air sensor:

Test air sensor by placing sensor in ice water bath and using an ohmmeter set on the ohm scale. The

reading should be 100 ohms resistance. If it is more than 2 ohms higher or lower, sensor needs to

be replaced.

D. To test probe sensor:

Test food probe by placing in ice water bath and using an ohmmeter set on the ohm scale. The reading

should be 100 ohms resistance.
