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 · MicrowaveRule out metal in the cavity first (foil, twist ties, metal-trimmed dishes, a rack on a model not meant for it). The most common part failure is a grease-soaked, carbonized waveguide cover. Chipped cavity paint and a damaged magnetron antenna cap are next. Stop using the unit until fixed, since continued arcing can damage the magnetron.
Guide · MicrowaveCooktop light: wrong bulb type or a light timer setting are common causes. Cavity light on with door closed points to a door switch not releasing or a stuck relay on the control board.
