Lg Microwave 80409 Parts

Board Assembly,Latch
Genuine Lg part
By: Lg
Part Number: 3501W1A019D

The Door Latch Housing and Interlock Switch Assembly is an OEM replacement part for LG microwaves. It consists of the protective door latch housing casing along with the two-door switches and interlock switch.

The interlock switch prevents microwave energy from being generated inside the oven when the door is open. It shuts off all power once a faulty seal is detected between the door and cavity.

Symptoms of issues can include:

  • Microwave failing to turn on or cook with the door open
  • Sparking or arcing seen near the door seal or frame
  • Error codes displayed related to interlock detection faults

Compatible models include some GE, Kenmore, and Samsung units using matching door designs sourced from LG.

Door Latch Hook
Genuine Lg part
By: Lg
Part Number: 4026W2A015A

The Door Latch Hook is an OEM replacement part for LG microwaves. Located internally on the door frame, this metal hook secures firmly into the microwave's door latch bracket when closed. As a common wear point, the hook can experience minor warping over many years of use.

Symptoms of a bad latch hook include:

  • Door that does not close fully or completely latch in place  
  • Gaps forming in the door seal when shut
  • Inability to achieve a tight, solid seal around the perimeter 
  • Latch hook failing to grasp the bracket securely

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

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.

The glass reinstalled into the retainers in the door without a... Read more

My husband fixed the microwave by first discharging the capacitor so he wouldn't get shocked or killed. He then replaced the diode which wasn't the cause of the problem but was cheap to do. He then replaced the magnetron. Problem solved! He's great! Thanks for the parts! It was easy to find what we needed, the prices were reasonable, and shipping was fast! Read more
