Possible Causes

Damaged internal insulation, Missing or misaligned heat shield, Blocked ventilation, Operating too close to walls or other appliances

How to Fix / Troubleshooting

Safety first: Avoid touching metal surfaces during operation. Keep children away from the appliance while in use.

Steps to reduce exterior temperature:

  • Ensure clearance: Maintain at least 4–6 inches of space around the air fryer on all sides.
  • Check vents: Make sure intake and exhaust vents are not blocked.
  • Inspect internal shields: With the unit unplugged and cooled, remove the cover and verify that reflective heat shields and insulation are in place and not damaged or displaced.
  • Replace damaged insulation: If insulation is charred or missing, replace with LG-specified high-temperature insulation materials.

Note: The exterior will get warm during use, but it should not be dangerously hot. If it is, discontinue use until repaired.
