Customer Questions and Answers for Interlock Switch by Whirlpool

This Whirlpool Microwave Interlock Switch is an OEM part compatible with certain Whirlpool microwave models. As a crucial safety component, this interlock switch ensures the microwave only operates when the door is securely closed, preventing accidental exposure to microwave radiation. 

Interlock switches in microwaves can fail due to repeated use, mechanical wear, or misalignment. A malfunctioning interlock switch can lead to the microwave refusing to start, operating with the door open, or intermittent operation, all of which pose significant safety concerns.

Symptoms of a defective microwave interlock switch include:

• The microwave does not start or heats intermittently.
• The microwave starts operating when the door is open.
• Unusual noises when closing or opening the microwave door.
• The microwave stops suddenly during operation.
• The display or controls are unresponsive despite the door being closed.

This genuine Whirlpool OEM replacement part is compatible with Maytag, Jenn-Air, and Kenmore models.
