This air tunnel directs heated air from the blower assembly into the dryer drum to maintain proper airflow and drying performance. Replaces a cracked or damaged duct to restore efficient air circulation and reduce drying time variability. What it does:

• Channels warm air from the blower to the drum for consistent drying and heat distribution
• Helps maintain proper venting and prevent hot spots that can cause uneven drying
• Commonly needed when cracks, breaks, or blockages cause poor airflow or extended dry cycles
• Contributes to normal operating airflow; damaged tunnels may lead to longer run times or reduced efficiency

• Disconnect power to the appliance before beginning any repair
• Access typically requires removing the dryer's front or rear panels
• Inspect surrounding seals and fasteners; replace any broken clips or gaskets to ensure a proper seal
• If you smell burning or see significant lint buildup, clean the lint and vent system before reassembly; consider a full vent inspection

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.
