LG Dryer: overheating

Professional Repair Guide

What is this symptom?

Experiencing overheating issues with your LG dryer? If the dryer feels excessively hot during operation, or if your clothes are hotter than usual post-cycle, it's likely due to restricted airflow or other internal issues. This can lead to longer drying times and potential damage if not addressed promptly.

Urgency: High

Important Tips for LG Models

  • LG support notes restricted airflow (clogged vent) and incorrect cycle interruption as causes of clothing too hot and possible overheating; clean vent annually.

Possible Causes

Restricted Airflow (vent/duct blockage)

How to Identify: Dryer cabinet gets very hot, clothes take longer to dry, lint accumulation visible in trap or vent, outside vent flap not opening

Part: Dryer vent system/lint trap

Faulty Thermostat (cycling or high-limit)

How to Identify: Dryer heats continuously without proper regulation; multimeter continuity test shows faulty thermostat; no shutoff at high temps

Part: Cycling thermostat or high-limit thermostat

Shorted or Damaged Heating Element

How to Identify: Heating element stays energized, visual inspection shows coil damage or continuity to casing, excessive heat even at lower settings

Part: Heating element assembly

Blower Wheel / Air Circulation Issues

How to Identify: Reduced airflow inside drum, longer drying times, visible lint/debris on wheel, wobbling wheel

Part: Blower wheel

Overloading or Incorrect Settings

How to Identify: Overheating occurs when dryer is heavily loaded or wrong heat setting used; vents work normally

Part: User operation
