Before you order, use Confirmed Fit
For advice and repair topics like this one, the biggest buying mistake is ordering on appearance alone. Search by the exact model number wherever possible, because small appliance revisions can use different seals, filters, motors, pumps, lamps, shelves, or trims.

At a Glance
- This guide covers the most likely causes of this tumble dryer problem and how to diagnose them.
- Start with the simple checks before moving on to part-related faults.
- Estimated time: 20-60 minutes depending on access and fault.
Safety First
Disconnect the appliance from the mains before removing panels or testing parts. Shut off water where relevant, and stop if you see damaged wiring, smell burning, or suspect a gas or sealed-system refrigeration fault.
Common Causes
- Blocked filter, condenser, or vent causing overheat cut-out
- Failed heating element on vented or condenser models
- Faulty thermostat or thermal cut-out
- Power-supply issue on some electric dryers
- Control or sensor fault on newer machines
Quick Checks First
- Clean the lint filter and all airflow paths first.
- For condenser models, clean the condenser assembly if applicable.
- Check whether the drum turns normally but clothes stay cold.
- Look for signs the appliance has overheated, such as repeated cut-out or very poor airflow.
- Test heat-related components only after isolating power.
Diagnosis and Fix by Cause
Airflow restriction
- Poor airflow is a major cause of weak drying and heater cut-out.
- Clean filters, ducts, condenser channels, and external venting where fitted.
Heater or thermostat fault
- If airflow is good but there is still no heat, the heater or associated thermostats may be open-circuit.
- Replace failed cut-outs or thermostats only after fixing the reason they overheated.
Electrical or control issue
- On some appliances, part of the supply can fail leaving the motor running but no heat generated.
- After mechanical checks, inspect wiring and heat-control components.
