3B73362F LG Microwave Door Switch

Microwave Door Switch for LG Models.

LG's product lineup includes brands such as LG and Sears-Kenmore. This Microwave Door Switch is a genuine OEM replacement part designed for LG countertop microwaves. Its function is to electrically monitor the door's position, ensuring the microwave does not operate if the door is not properly closed.

Common indicators of a malfunctioning door switch are:

- The microwave fails to start or pause unless the door is fully closed.
- Display errors indicating that the door is open.
- Inconsistent recognition of whether the door is open or closed.
- Contact issues after prolonged usage.

Typically, these problems arise from normal deterioration of the electrical components and contacts due to frequent use. Additionally, moisture from spills can affect the switch's sensitive circuitry over time.

This authentic LG replacement switch is also suitable for use with Sears/Kenmore microwave models.

Replacing this part can resolve issues such as:

- The microwave not heating.
- The microwave failing to start.
- The microwave turning off shortly after starting.
