Product Description
The Sharp Secondary Interlock - QSW-MA168WRZZ is a safety-critical component used in microwave ovens to detect door closure and authorize oven operation. When the door is properly closed, the interlock switch signals the control board that it is safe to energize the high-voltage system. A faulty interlock can prevent the microwave from starting, cause intermittent operation, or pose safety issues. Replacing a malfunctioning interlock switch restores proper door monitoring and ensures the microwave operates only when the door is securely closed.
