A dryer blowing cool air does not always have a failed heater. The programme, appliance type, filter condition and moisture in the load matter. Heat-pump dryers work differently from conventional dryers. Record the model and cycle before arranging a repair. Stop for unusual heat, a burning smell or a safety warning.
Describe heat and dryness separately
Cool air during the programme
Some programmes use unheated air and some include a cooling stage. Check the selected setting in the manual. A touch at the door is not a reliable measurement of the heating system.
Warm air but damp laundry
Describe the load size and whether the washer completed its spin. Poor airflow and excess starting moisture can extend drying. Use the dryer overview guide for the details needed before a visit.
Use the model’s owner maintenance routine
Wait for the appliance to stop and cool. Clean the lint filter and empty a water container only as the manual directs. Condenser access and heat-pump care differ between models. Do not dismantle a sealed heat exchanger or run the dryer without its filter. Bosch’s heating support explains why a persistent fault needs service. Samsung’s drying guidance discusses load and drying conditions.
Keep heating and safety work out of DIY checks
Do not bridge a thermal cut-out, open electrical covers or work on a gas-heated dryer. Stop if it overheats or smells burnt. An accessible lint filter and building exhaust ductwork are different maintenance scopes. Confirm the duct-cleaning arrangements separately.
Send the installation and cycle details
Tell us whether the machine is vented, condenser, heat-pump or a washer-dryer. Send the model, programme, fault code and whether the drum rotates. Mention stacked installation and cabinet access. Our dryer repair service checks the reported fault before recommending a part.
Agree a repair based on testing
A heater, sensor, airflow restriction and control fault require different work. Ask for the findings, parts availability and total quote. Compare replacement including installation and your intended load capacity. If the sound has changed, read the dryer noise guide. See repair pricing and request a dryer inspection.
Frequently asked questions
Using the appliance
Does cool air prove the heater failed?
No. Programme stages, settings and appliance type need checking first.
Should a heat-pump dryer feel as hot as a vented dryer?
The technologies operate differently. Judge performance using the model instructions and load result.
Can I clean the lint filter?
Use the owner maintenance steps in your manual after the machine stops and cools.
Booking and repair
Can I bypass a thermal cut-out?
No. It is a safety device. Leave internal heating work to a technician.
What should I send for a dryer visit?
Send the model, type, programme, error and whether the drum turns.
