LG Dryer not heating

A dryer that tumbles without heat can involve airflow, settings, supply power, thermal protection, heating element or gas ignition.

What this evidence points to

Begin with airflow and supply checks. Electric and gas dryers require different later steps.

LG uses model-specific support pages and several appliance error-code families. Confirm the complete suffix when possible. Begin with airflow and supply checks. Electric and gas dryers require different later steps.

LG context that changes the path

Terminology
LG DLE and DLG prefixes commonly distinguish electric and gas dryer families.
Model detail
Use the complete model to avoid applying electric supply checks to a gas heat system.
Diagnostic order
Airflow remains an early check; the subsequent heat path depends on electric versus gas configuration.
Safety boundary
Never bypass a thermal fuse or operate with a restricted vent.
Official LG support →
Stop condition

Never bypass thermal fuses or operate a dryer with signs of overheating.

Likely next actions

General order until you add inputs
1

Check lint screen and full vent airflow

Clean the lint screen and inspect the exhaust path to outdoors.

Verify cycle settings and supply power

Confirm the cycle calls for heat and an electric dryer has full supply voltage.

Test thermal protection and heating components

Have the thermal fuse, element or gas ignition path tested.

Frequently asked questions

Should I replace a part based only on an error code?

No. A code identifies a detected condition, not necessarily the failed component. Rule out safe, inexpensive causes and confirm the exact model.

Why ask what I already tried?

The best next action changes when earlier checks fail. The engine removes repeated actions and applies prerequisite rules before ranking what remains.

Are success rates verified?

Every rate shows its denominator. Photo, receipt, invoice, technician and follow-up verification remain separate signals; none converts a small sample into high confidence.
