This AC circulation motor drives internal circulation in compatible LG appliances to restore proper flow and help the unit operate as intended. Replace a worn or failed motor to recover normal circulation and performance. What it does:

• Spins the internal circulation mechanism to maintain proper flow where required by the appliance
• Helps support consistent operation of systems that rely on active circulation
• Common symptoms: no circulation, reduced system performance, or related error indications

• Disconnect power (and water, if applicable) before beginning any service
• Handle the motor and connectors carefully to avoid damage to wires or mounting points
• Reassemble panels and test the appliance operation after installation

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.

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.

Causes of a bad door latch hook include normal wear and tear, loss of tension, or deformation from frequent door opening and closing cycles long-term.

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.
