LG Washer Dryer: not heating
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.
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
