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.
