Latch
Genuine Lg part
By: Lg
Part Number: 4026W2A019C

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.

Do-It-Yourself Stories from Customers like You Glass fell out of its retainers and plastic clips holding the frame assembly to the door broke off   Steve C. • Caledonia , WI • September 23, 2015

Careful placement of new screws into the inside of the outer door that now hold the frame assembly to the door secured the frame assembly to the outer door. All of the other parts I bought and replaced were a waste of money. I figured since I had them I might as well install them anyways. Easier than sending them back since I had the whole thing apart anyways. The part I really needed was no longer available, the outside door. The glass reinstalled into the retainers in the door without a... Read more
