Quick Answer: What Does LG Dryer Error Code HE Mean?
LG dryer error code HE stands for Heating Error. It means the dryer is running, but it is not producing enough heat or the heating system is not operating correctly.
This protection feature is built into dryers manufactured by LG Electronics to prevent damage and ensure safe drying temperatures.
Common Symptoms of HE Error
Dryer runs but no heat
Clothes remain cold and wet
Dryer stops mid-cycle
Drying cycles take much longer than normal
HE error appears shortly after starting
Main Causes of LG Dryer HE Error
The most common reasons include:
Failed heating element
Faulty gas igniter (gas dryers)
Defective thermostats or thermal fuse
Wiring issues in the heating circuit
Control board not sending power to heater
Restricted airflow causing heater shutdown
Fast Troubleshooting Checklist (DIY)
Step 1: Power Reset
Unplug the dryer for 5–10 minutes
Plug it back in and restart
✔ Sometimes clears temporary control glitches
Step 2: Check Airflow First
Poor airflow can shut down the heater.
Clean lint filter
Inspect vent hose for blockages
Ensure outside vent flap opens properly
Step 3: Identify Dryer Type
Electric Dryer
Heating element may be broken or burned out
One side of the power supply may be missing (240V issue)
Gas Dryer
Igniter may not glow
Gas valve coils may be faulty
No gas supply or closed valve
Step 4: Inspect Heating Components (Advanced)
Unplug dryer
Remove rear or front panel
Check heating element, thermal fuse, and thermostats
Look for burn marks or broken wires
⚠️ Any failed heating part must be replaced.
Can You Use the Dryer With an HE Error?
No. Using the dryer with an HE error can:
Waste electricity or gas
Overheat internal parts
Damage the control board
Cause repeated cycle failures
The dryer may continue tumbling but will not dry clothes properly.
When to Call a Technician
Call for service if:
HE error returns after reset
Heating element tests bad
Thermal fuse is blown
Gas components fail ignition
Control board is suspected
Heating repairs should be handled carefully due to electrical and fire risks.
Prevention Tips
Clean lint filter after every load
Deep-clean dryer vents annually
Do not overload the dryer
Ensure correct power supply or gas flow
Good airflow keeps the heating system stable and efficient.
