Microwave Oven troubleshooting guides

Practical first checks for common symptoms. Exact diagnosis and error-code meanings vary by brand and model.

Power settings, door interlocks or internal high-voltage components may be involved; internal repair is for qualified technicians.

Check that the turntable is seated correctly and the roller ring is clean; drive faults need inspection.

Stop the cycle immediately. Check for metal, foil, damaged cavity coating or unsuitable cookware; do not use it if sparking continues.

Check the outlet, plug and door closure; never bypass the door interlock.

A control lock, moisture on the panel or electronic control fault may affect operation.
