Possible Causes
Failed element in one cavity, Faulty thermostat for that cavity, Wiring fault specific to one oven, Faulty relay on PCB for that cavity
How to Fix / Troubleshooting
Safety: Isolate power before testing elements or thermostats.
- Identify affected cavity: Confirm which oven (top or main) is not heating.
- Test that cavity's element(s): Measure resistance of the relevant elements from the rear. Replace any open elements.
- Check that cavity's thermostat/sensor: Test for continuity (mechanical) or correct resistance (electronic). Replace if faulty.
- Inspect wiring and relays: Trace wiring from the PCB or selector to the affected cavity. Repair any faults; if wiring is good, suspect the relay on the control board.
