Quick summary
Heat-pump dryers run gently warm rather than hot—that's normal. If there's no warmth at all, clean the lint filters and the condenser/extra filter for your model. Persistent problems or tE codes need a technician.
Before deciding a dryer isn't heating, know its type. Common heat-pump dryers dry at relatively low temperatures to save energy, while traditional dryers use a hotter heating element.
Unplug the appliance, close the water tap if there's a leak, and never open covers that need tools or expose wiring or circuits.
Possible causes
Clogged lint filters
Reduce airflow so the system heats incorrectly or shuts off.
Blocked condenser/heat-pump filter
On heat-pump models this affects heat exchange.
Temperature sensor
Wrong reading (tE1/tE2/tE3 on models that use them).
Heating element or thermostat
On element dryers.
Very cold room
Low ambient temperature affects heat-pump performance.
Safe checks you can do
- Clean the lint filter before every cycle.
- Clean the extra filters/condenser per your manual.
- Make sure you didn't select an air-only program.
- Leave ventilation space around the dryer.
- On heat-pump models, empty the condensed-water tank if full.
When to stop checking immediately
- Don't open the dryer to reach the element or heat-pump circuit.

When do you need a technician?
The technician tests sensors, thermostats, the element or heat-pump compressor performance and checks the whole airflow path.

FAQ
Should a heat-pump dryer feel very hot?
No—it runs cooler than traditional dryers, so moderate warmth is normal.
What does tE mean on a dryer?
A temperature-sensor problem per LG's code tables. See the dryer codes.
