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

User Suggested Solutions

Inspect and clean the venting system. Disconnect the dryer from power, remove the vent hose, and clean it thoroughly. Ensure that the venting path is clear of obstructions. Reattach the vent hose and test the dryer.
Check and replace the thermostat if faulty. Disconnect power, locate the thermostat (usually near the heating element), test it with a multimeter for continuity, and replace it if necessary.
Clean the lint filter and drum. Remove the lint filter and wash it with soap and water to remove any residue. Wipe down the inside of the dryer drum with a damp cloth to remove lint buildup.
