Why is my LG dryer running but not heating?

This could be due to a tripped breaker, clogged vent, or a faulty heating element or fuse.

Does 'Air Dry' mean no heat?

Yes. Air Dry or Air Fluff settings use only room-temperature air to dry clothes. Switch to a heat cycle if needed.

How do I know if the heating element is bad?

If there’s no heat on any setting and the drum spins normally, the heating element may be burned out.

Can I replace a thermal fuse myself?

Technically, yes, but it involves opening the unit and testing electrical components. If unsure, it's advisable to consult a professional.

Diagnostic and Troubleshooting Steps

Is Your LG Dryer Not Heating? This step-by-step guide walks you through everything from power issues to heating elements and safety fuses, offering practical solutions to get your dryer working again.

Step 1:

Check the Cycle Setting

Make sure your dryer isn’t set to “Air Dry,” “Air Fluff,” or “Delicate,” which use little to no heat. Switch to a standard timed or sensor dry cycle with a medium or high heat setting and try again.

Step 2:

Reset the Circuit Breaker

Electric dryers use two circuit breakers: one for the motor and one for heat. Check your home’s breaker panel and reset both breakers (turn them fully off, then back on). If only one tripped, the dryer may run without heat.

Step 3:

Clear the Lint Trap and Vent

Lint buildup can restrict airflow and cause overheating, which triggers safety devices to cut off heat. Clean the lint trap thoroughly and inspect the vent hose for clogs. Also, check the outside exhaust vent for blockages.

Step 4:

Test the Heating Element

If the drum spins but no heat is produced on any setting, the heating element may be burned out. This part typically needs to be tested with a multimeter and replaced—something best handled by a qualified technician.

Step 5:

Inspect the Thermal Fuse or Thermostat

These components monitor temperature and shut off power if the unit gets too hot. If either part fails, the dryer may stop heating altogether. Testing requires removing the back panel and checking continuity with a multimeter.

Key Actions for Homeowners

Double-check that your selected cycle uses heat.
Reset the circuit breakers even if the dryer powers on.
Clean the lint trap after every load and inspect the vent system monthly.
If the unit runs cold, suspect the heating element or thermal fuse.
Call in a professional if electrical testing or internal access is needed.

Most Common Repairs Needed to Fix an LG Dryer Not Heating

When your dryer isn’t producing heat, certain repairs are more commonly required than others. Below are the most frequent fixes:

Switching to a Heated Cycle: Prevents air-only settings from confusing users.
Breaker Reset or Replacement: Restores full power to the heating circuit.
Cleaning the Lint Vent System: Improves airflow and prevents future overheating.
