Dryer not heating?
A dryer that tumbles without heat has a different symptom from one that gets hot but leaves clothes damp. Check the cycle selection and lint screen, and tell the team whether your dryer uses gas, electric heat, or a heat-pump system.
What’s happening?
Safe checks to try
Check the drying cycle
Make sure an air-only, fluff, or cool-down setting is not selected when you expect heat. Heat-pump dryers operate differently from conventional models, so check your model’s manual before judging the temperature.
Clean the accessible lint screen
With the dryer stopped and cool, remove lint from the user-accessible screen as the manual describes. Do not run the dryer without its screen or reach into the lint housing with tools.
Look for a visible airflow restriction
For a vented dryer, note any crushed duct visible without moving the machine or an outside vent blocked by debris that you can see from ground level. Do not disconnect ducting or climb to inspect an outlet; stop use if drying remains unusually hot or slow.
Possible causes
No heat may involve a cycle setting, an electrical supply problem, a heater or temperature-control fault, or an ignition issue on a gas model. Warm but damp clothes can instead point to restricted airflow, an unsuitable load, or an incomplete drying cycle. The checks and components differ for vented, condenser, and heat-pump dryers, so the exact model is important.
Stop using the dryer if it smells burnt, becomes unusually hot, or produces smoke. Do not open panels, test wiring, bypass a thermal safety device, or adjust gas connections. If you smell gas, leave without operating switches and call 911 or your gas utility from a safe location; do not wait for a repair callback.
What to have ready
- Brand, model number, and dryer type if known
- Whether the drum turns and the air stays cool or becomes warm
- Selected cycle, approximate drying time, and any error message
- For a vented dryer, any recent vent work or visible duct restriction
Questions about this symptom
The drum can turn even when the heating function is not working. A setting, power-supply problem, or heating component can be involved; the symptom does not identify a replacement part by itself.
Heat alone does not guarantee effective drying. On a vented model, restricted airflow can extend drying time, while the load and cycle also matter. Stop use if the dryer is unusually hot and describe the difference between heat and drying performance.
This guide does not include internal electrical or gas work. Keep checks to the controls and user-accessible lint screen, and leave component testing and gas connections to a qualified professional.
Yes, its operation and maintenance differ from a conventional vented dryer. Use the model’s manual for user-accessible filters and care instructions, and include the model in your request so service suitability can be discussed.
