LG Dryer HE Error Code — What It Means
HE stands for a heating error. The control board checked the heating circuit and found that no heat is being made, so it stops the cycle to keep you safe.
Common Causes
- Blown thermal fuse A one-time safety fuse trips after an overheat and cuts power to the heating circuit until it is replaced.
- Failed heating element On electric models the coiled element can break or short internally after years of heat cycles.
- Open high-limit thermostat A safety thermostat stuck open will interrupt the heating circuit and stop all heat.
- Restricted vent A clogged exhaust vent causes overheating that blows fuses and thermostats again and again.
- Gas ignition fault On gas models a bad igniter, flame sensor, or gas valve coil keeps the burner from lighting.
Step-by-Step Fix
- Unplug the dryer and shut off the gas valve on gas models before you open any panel.
- Clear the vent by cleaning the lint filter, the rear exhaust hose, and the outside vent hood.
- Open the cabinet and find the heating element housing along the back or bottom of the drum.
- Test the thermal fuse for continuity with a multimeter and replace it if it reads open.
- Test the heating element for continuity and look for visible breaks or burn marks in the coil.
- Check the high-limit thermostat for continuity and swap it if it reads open at room temperature.
- Reassemble and run a test cycle, then watch that the new fuse does not blow again.

When to Call a Pro
On gas dryers the igniter, flame sensor, and gas valve sit on the burner and involve a live gas line, so bring in a licensed appliance pro for that work. Call a pro too if the new fuse keeps blowing after the vent is clean, since that points to a deeper wiring or control fault.
