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.
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.
Guide · MicrowaveMost cases are installation: the blower was never rotated from the factory recirculate setup, the damper is taped or stuck, or the duct is the wrong size, crushed or too long. Clogged filters and a grease-packed blower wheel are next.
