01 · BEFORE BOOKING
A simple check.
Confirm the cooking mode and temperature, and allow the normal preheat cycle to finish. Record any displayed error rather than repeatedly restarting the oven.
02 · UNDERSTAND THE SYMPTOM
What it could mean.
Uneven cooking and no heat are different symptoms. Heating components, temperature sensing, ignition on gas models or controls may need diagnosis.
03 · THE NEXT STEP
When diagnosis helps.
I check the relevant heating functions and temperature-control system before recommending parts. A calibration adjustment is not a substitute for fixing a failed component.
This is general guidance, not a diagnosis of your appliance. Follow the owner’s manual for your exact model. Internal electrical, gas and refrigerant work belongs with a qualified professional.
