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 · MicrowaveMost OTR microwaves have a heat-protection thermostat that starts the vent fan when the cooktop below heats the unit, and on that cycle the fan cannot be switched off until the area cools. Some models also run the fan during and after microwave cooking or link the hood to the cooktop. If the fan runs in a cool kitchen, right at power-up, or for hours, suspect a thermostat stuck closed, a welded fan relay on the control board, a stuck vent key or a shorted wire.
Guide · MicrowaveRule out an obstruction, an overloaded drawer, the control lock and a power interruption, then reset at the breaker. Persistent faults point to the position/sensing switch, drawer motor, slides or the control; check for oversized mounting screws on new installs.
