LG Dryer: overheating and pausing
What is this symptom?
Is your LG dryer overheating and pausing mid-cycle? This issue often results in longer drying times and clothes that feel excessively hot. The dryer may shut off as a safety precaution to prevent damage. Understanding the common causes can help you troubleshoot effectively.
Important Tips for LG Models
- LG’s official support notes restricted exhaust duct can cause overheating and recommends cleaning annually
Possible Causes
Restricted airflow (lint filter or blocked vent)
How to Identify: Dryer overheats before shutdown; longer drying times; visible lint buildup; air does not flow freely from exterior vent
Part: Lint filter and vent system
Faulty thermostat or thermistor
How to Identify: Dryer overheats even with clear airflow; components fail continuity tests on multimeter; thermal cut‑offs trigger prematurely
Part: Cycling thermostat/high‑limit thermostat/thermistor
Malfunctioning drive motor or blower wheel
How to Identify: Dryer runs then stops; insufficient airflow; blower wheel damage or motor overheating
Part: Drive motor and blower wheel
Thermal fuse tripping
How to Identify: Dryer pauses or won’t restart until fuse replaced; no airflow issue found; multimeter shows open fuse
Part: Thermal fuse
Faulty control board or timer
How to Identify: Erratic stopping unrelated to temperature or airflow; diagnostics indicate control errors
Part: Control board/timer
DIY Solutions
Clean lint filter and dryer vent
- Unplug dryer and pull unit away from wall
- Remove and clean lint filter
- Disconnect vent hose and vacuum out lint from hose and dryer vent
- Use vent brush to clean full length of vent to exterior
- Ensure exterior vent flap opens freely and reconnect hose
Test and replace thermostats/thermistor
- Unplug dryer and access back panel
- Locate cycling and high‑limit thermostats and thermistor near heating element/blower housing
- Use multimeter to test for continuity per part specifications
- Replace any part that fails continuity test
- Reassemble and test dryer
Inspect and fix blower wheel/motor airflow
- Unplug and remove dryer panels
- Locate blower wheel and inspect for damage or obstruction
- Ensure blower spins freely and is securely mounted
- Replace defective blower wheel or motor as needed

- Faulty thermostat
- Overloading the dryer
User Suggested Solutions
-
Clean the lint trap and vent system. Disconnect the dryer from power, remove the lint trap, and clean it thoroughly. Inspect and clean the vent hose and duct to ensure there are no blockages.
-
Replace the faulty thermostat. Unplug the dryer, locate the thermostat (usually near the heating element), and test it with a multimeter. If defective, replace it with a new one.
-
Reduce the load size. Ensure that the dryer is not overloaded, as this can cause overheating and pausing. Divide larger loads into smaller ones and try drying them separately.
