Possible Causes
One of multiple elements failed (e.g., lower element open), Weak or damaged element, Misreading temperature sensor, Door seal heat loss
How to Fix / Troubleshooting
Safety first: Isolate power before testing components.
- Compare modes: Test conventional bake, grill, and fan-assisted modes separately. If one mode is significantly weaker, its associated element may be faulty.
- Test elements: Measure resistance of each element and compare to specifications. Replace any element with significantly higher resistance or open circuit.
- Check door seal: Inspect the door gasket for gaps, tears, or compression. Replace the seal if heat is visibly escaping around the door.
- Verify temperature: Place an oven thermometer inside and compare actual temperature to the set value. If consistently low, the sensor or control calibration may be off; replace the cavity sensor first.
