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.
