What Does LG Dryer Error Code FE Mean?
LG dryer error code FE means the dryer has detected abnormally high internal temperature. To prevent damage or fire risk, the dryer shuts down and displays the FE code.
This safety protection is built into dryers from LG Electronics to stop operation when overheating is detected.
What Are the Most Common Signs of the FE Error?
Dryer stops suddenly during a cycle
FE code appears on the display
Dryer feels unusually hot
Clothes may be very hot at the end of a cycle
Dryer refuses to restart until it cools down
Why Does LG Dryer Error Code FE Occur?
The FE error is usually caused by overheating, not a software issue.
Common reasons include:
Severely restricted airflow
Clogged lint filter or exhaust vent
Blocked or crushed vent hose
Faulty temperature sensor (thermistor)
Defective thermostat or control board
Running dryer in a very hot environment
How Do You Fix LG Dryer Error Code FE?
Step 1: Let the Dryer Cool Down
Turn off the dryer
Unplug it for 30–60 minutes
Allow internal temperature to normalize
Step 2: Clean the Lint Filter
Remove all lint buildup
Wash the filter with water if coated with residue
Dry completely before reinstalling
Step 3: Inspect and Clean the Vent System
Check vent hose for kinks or blockage
Clean lint from the entire duct
Ensure outside vent flap opens freely
Restricted airflow is the number one cause of FE errors.
Step 4: Check Dryer Placement
Ensure proper space around the dryer
Avoid placing it in a poorly ventilated or very hot area
Step 5: Test the Dryer
Restart a normal cycle
If airflow is restored, the FE code should not return
Can You Use the Dryer With an FE Error?
No. Using the dryer while overheating can:
Damage internal wiring
Burn heating components
Trip thermal fuses
Create fire hazards
The dryer may lock itself until temperatures return to safe levels.
When Should You Call a Technician?
You should seek professional repair if:
FE error returns after full vent cleaning
Dryer overheats even with good airflow
Temperature sensor tests faulty
Control board fails to regulate heat
How Can You Prevent LG Dryer FE Error?
Clean lint filter after every load
Deep-clean dryer vents every 6–12 months
Do not overload the dryer
Avoid long drying cycles on high heat
Maintain proper ventilation around the dryer
LG dryer error code FE is an overheating warning, most often caused by restricted airflow or ventilation issues. Cleaning the vent system and allowing the dryer to cool usually resolves the problem. Persistent FE errors may indicate a sensor or control board issue requiring professional service.
