Runs But Does Not Heat
A microwave that lights up, hums, and turns the plate but leaves food cold has a heating fault, and a running fan or lit display does not mean it is heating normally. Several parts in the heating circuit can cause this, so it takes testing to know which one has failed. Settings can cause it too: Whirlpool’s microwave not-heating guidance for its over-the-range models covers control lock, demo mode, and power level. Check your own manual for the equivalent settings.
