Hello there and thank you for choosing fixya
The F-2 error code Indicates that
oven is over temperature in one of the following modes within
either a cooking or clean mode of operation.
· Control senses oven temperature
above 650 degrees F with the door circuit in the unlock mode.
· Control senses oven temperature
above 935 degrees F with the door in the locked mode.
· Stalled cooling fan or airflow
problem.
·
Look for welded relay
contacts. (Heating elements on in off mode).
· Look
for open thermal switch in lock motor circuit. Switch is normally
closed and will open if area overheats due to fan not operating.
Look for cause - fan thermal switch not closing, fan stalled,
etc.
· Look
for high resistance in the oven temperature sensor circuit
due to high contact resistance (poor terminal crimp, deformed
terminals, loose connection) or intermittent solder joint
on control or intermittent oven temperature sensor.
· Look
for electrical noise interference in the oven temperature
sensor circuit (Ham radio, cordless phone, etc.).
