What is actually happening
On a conventional dryer this is usually a failed element or a tripped thermal cut-out, and the cut-out normally trips because airflow was restricted — so replacing the part without clearing the fluff simply repeats the fault. On a heat pump dryer there is no element at all, and a dryer that runs a full cycle without heat and reports nothing is a different diagnosis entirely.
The usual causes
- A failed heating element
- A tripped thermal cut-out, usually caused by blocked airflow
- A blocked lint filter, condenser or vent hose restricting air
- On heat pump models, a refrigerant or compressor fault rather than an element
- A failed thermostat or sensor
What you can safely check yourself
Work through these in order. Anything past this point — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the appliance plugged in.
- Clean the lint filter, and on a condenser model pull out and rinse the condenser block
- Check the vent hose is not crushed, kinked or full of fluff
- Note whether it is a heat pump model — the diagnosis and the cost are quite different
Still not heating?
Most of these need an engineer once the checks above are done. £66 including VAT for an engineer to come out and diagnose it, or £84 in total including VAT if it is put right on the visit and no parts are needed.

Common questions
Why is my tumble dryer not heating?
The drum turns and the cycle runs, but the clothes come out cold and damp. On a conventional dryer this is usually a failed element or a tripped thermal cut-out, and the cut-out normally trips because airflow was restricted — so replacing the part without clearing the fluff simply repeats the fault. On a heat pump dryer there is no element at all, and a dryer that runs a full cycle without heat and reports nothing is a different diagnosis entirely.
Can I fix a tumble dryer not heating myself?
Clean the lint filter, and on a condenser model pull out and rinse the condenser block. Check the vent hose is not crushed, kinked or full of fluff. Note whether it is a heat pump model — the diagnosis and the cost are quite different. Beyond those checks this one normally needs an engineer.
