Guide · MicrowaveSensor programs depend on a humidity or vapor sensor and a correct load. Most failures are usage (tight covers, tiny loads, hot cavity) or grease on the sensor; a failed sensor or wiring shows a code.
Guide · MicrowaveMid-cook shut-downs usually mean a thermal cutout is opening because the cooling fan failed or the vents are blocked, or a marginal door switch is opening. Check airflow and installation first, then the fan, cutouts and switches with the HV capacitor discharged.
Guide · MicrowaveStart with bulbs, grease filters and the fan's thermal protection. A fan that runs by itself is often a stuck relay on the control board or the board's automatic hot-cooktop protection reacting to heat below. Fan motor and relay tests are internal: high-voltage warning applies.
