Frigidaire 5304440026 Microwave Micro Door Relay Switch 5304493153

Microwave Door Relay Switch – Frigidaire

The door relay switch (also called a micro switch) monitors the position of the microwave door and signals the control board to allow or cut power to the magnetron. When it fails, the microwave may not start, stop mid-cycle, or run with the door open — a serious safety hazard. This direct-replacement switch restores safe, proper door interlock operation.
