The Latch is an OEM part for LG microwaves. This component is critical for securing the microwave door, ensuring it remains closed during operation. The latch interacts with the door switch to enable the microwave to function only when the door is properly closed, maintaining safety and efficiency.

Over time, the latch can become worn or damaged due to frequent use, misalignment, or accidental impact. A faulty latch can lead to the microwave door not closing properly, resulting in the appliance not operating or shutting off unexpectedly.

Symptoms of a bad latch include:

• The microwave not starting or operating intermittently
• The door not closing securely
• The microwave running even when the door is open
• Audible clicking or unusual noises when opening or closing the door

This OEM LG part is also compatible with Sears/Kenmore models.
