Guide · MicrowaveRule out control lock first. Then the usual causes are a worn or moisture-damaged membrane keypad or a loose ribbon at the control board. Unplugging the keypad ribbon separates a bad keypad from a bad board. The control board sits next to high-voltage parts on most models.
Guide · MicrowaveA microwave that heats on its own is a fire hazard: unplug it and do not use it. The usual cause is a stuck relay or shorted triac on the control. On OTR units, a fan that starts by itself is often normal heat protection, and a light that stays on can be moisture.
