← Full guide: Oven Temperature Problems: Diagnose Before Booking Service
Oven reaches preheat, then temperature keeps falling and does not recover
That is not a normal calibration problem. If heat is reached once and then the oven fails to reheat, the cycling/heating/control path needs diagnosis.
Start here
That is not a normal calibration problem. If heat is reached once and then the oven fails to reheat, the cycling/heating/control path needs diagnosis.
Check these first
- Confirm the symptom with actual cooking/temperature observation after full preheat.
- Note whether the heating element/burner visibly cycles later.
- Record any error code and whether re-entering Bake makes heat return.
Fix it in this order
- Do not calibrate a falling-temperature fault.
- Check model-safe power/gas and door conditions.
- Have the heating element/ignition, sensor, relay/control and wiring path diagnosed using the model service information.
Evidence to keep
- Preheat reached
- Post-preheat temperature trend
- Whether reheating resumes after a command
Do not make it harder
- Buying a control board or sensor solely from an internet guess
How you know it is fixed
- The oven repeatedly cycles heat and holds usable average temperature after preheat.
If the obvious fix does not work
- If temperature actually oscillates around the setpoint and food cooks normally, that may be normal cycling.
- If only convection behaves differently, check conversion settings before service.
If this still isn't resolved
- Qualified appliance technician
