The Interlock is an OEM component specifically designed for Whirlpool microwaves. Located inside the door assembly, the interlock provides a safety function that prevents microwave energy from emitting when the door is opened. 

Composed of a magnet and lever switch beneath a metal shield, the interlock uses electromagnetic principles to immediately turn off microwave power if the door is opened during a cook cycle. This ensures safe access to hot food inside the cavity.

Causes of a bad interlock include worn contacts or weakening of the magnetic mechanism from sustained use over time. Physical damage or debris interfering with smooth lever operation are also possible causes.

Symptoms of a bad interlock include: 

• Microwave emission even with door slightly ajar  
• Faulty “door open” detection during cooking
• Inability to start new cycles until manually reset

This OEM part fits kitchen microwaves from Whirlpool, KitchenAid, Jenn-Air, and select Kenmore models.
