LG Micro Switch(primary) 3B73362F OEM Part

The Microwave Door Switch, compatible with LG and Sears-Kenmore models, serves as a genuine OEM replacement part specifically crafted for LG countertop microwaves. This component ensures the appliance does not function when the door is improperly closed by monitoring its position electronically.

Signs of a faulty door switch include the microwave's inability to initiate or pause unless the door is completely shut, error messages regarding an open door, inconsistent detection of door status, and connectivity problems caused by extended use.

These issues typically result from the inevitable wear and tear on electrical elements and contacts due to regular operation. Additionally, prolonged exposure to moisture from spills can compromise the switch's delicate circuitry.

This certified LG replacement part is also designed for compatibility with Sears/Kenmore microwaves.

Changing this switch can effectively address problems such as:

- The microwave's inability to heat.
- Failure to start the microwave.
- The microwave unexpectedly shutting off shortly after activation.
