Possible Causes
Failed element in one cavity, Faulty selector switch contacts, Broken wiring specific to one oven, Faulty thermostat for that cavity
How to Fix / Troubleshooting
Safety first: Disconnect from mains before testing.
- 1. Compare functions: Test each oven separately. Note which functions (fan, conventional, grill) work in each cavity.
- 2. Inspect elements: Check the non-heating cavity's elements for visible damage.
- 3. Test elements and thermostat: Measure resistance of the elements and thermostat for the faulty cavity. Replace any open-circuit components.
- 4. Check selector switch: On models with a rotary selector, inspect the switch for burnt contacts or loose terminals. Replace if faulty.
- 5. Trace wiring: Repair any broken or heat-damaged wires between the selector, thermostat, and elements.
