Possible Causes
Weak bake or broil element, Faulty temperature sensor, Control board not driving elements at full power, Poor door seal causing heat loss
How to Fix / Troubleshooting
Safety first: Disconnect power before testing elements or sensor.
- Check elements: Inspect bake and broil elements for damage. Test each for continuity with a multimeter and replace any open element.
- Test sensor: Measure oven temperature sensor resistance at room temperature (~1080–1100 Ω). Replace if out of range.
- Inspect door gasket: Check the oven door gasket for gaps, tears, or compression. Replace if it does not seal properly.
- Control board: If elements, sensor, and gasket are good, the control board may not be supplying full power. Replace the board if no other cause is found.
