Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Door movement is stiff, misaligned, or incomplete.
• Door does not latch or engage the interlock mechanism consistently.
• Microwave may not start or heat when the door mechanism fails to actuate the door switch; this symptom can have other causes.

Check Before Replacing

• With the appliance unplugged, visually inspect the door-support/sliding-arm area for visible cracking, bending, looseness, or misalignment.
• Open and close the door gently and observe whether the movement is smooth and whether the door reaches its normal closed position.
• Check for an obvious gap or abnormal door position compared with the cabinet; do not force the door or operate the microwave with damaged door components.
• Do not remove the microwave cabinet or test high-voltage components as part of a customer-level diagnosis.
