Lg Washer Dryer: not heating

Professional Repair Guide

What is this symptom?

Is your LG washer dryer combo running but not heating? This issue leaves clothes damp or cold, often due to faulty components like the heating element or thermal fuse, restricted airflow from clogged vents, or incorrect settings. Understanding these causes can help you troubleshoot effectively.

Urgency: Medium

Possible Causes

Faulty heating element

How to Identify: Dryer tumbles but no heat is felt; continuity test with multimeter shows no continuity.

Part: Heating element

Blown thermal fuse

How to Identify: Dryer runs but no heat; continuity test of thermal fuse shows open circuit. Often results from blocked airflow/overheating.

Part: Thermal fuse

Clogged vent or lint filter restricting airflow

How to Identify: Warm air isn’t exiting vent; lint accumulation visible in filter; dryer overheats or cycles longer, possibly blowing fuse.

Part: Vent system / lint filter

Incorrect dryer settings (no heat/air dry mode)

How to Identify: Dryer set to Air Fluff/Cool/Air Dry settings that do not engage the heating system; change to timed or heat cycle fixes it.

Part: Control panel/cycle settings

Faulty thermostat or temperature sensor

How to Identify: Dryer heats intermittently or not to temperature; multimeter testing shows thermostat out of spec.

Part: Cycling thermostat/temperature sensor

Power supply issue (electric/gas)

How to Identify: Electric dryer heating requires full 240V supply; one phase missing can cause no heat; gas dryer may lack gas flow or valve open issue.

Part: Power circuit or gas supply

Preventive Maintenance

  • Clean lint filter: Airflow blockages and overheating that lead to thermal fuse failure
    Frequency: after each load
  • Inspect and clean vent system: Clogged vents that restrict airflow and reduce heat efficiency
    Frequency: annually
