Your dryer runs, the drum spins, the clothes tumble, but they come out cold and damp. A dryer that runs but will not heat is one of the most common repairs, and the causes are limited to a short list. Here is what is really going on, how gas and electric dryers differ, what it costs, and the one cause you should never ignore because it is a fire risk.
Quick answer: A dryer that runs but will not heat almost always has one of these faults: a blown thermal fuse (usually caused by a clogged vent), a failed heating element on an electric dryer, or a bad igniter or gas valve on a gas dryer. A worn thermostat or thermistor can also be the culprit. The clogged vent behind many no-heat cases is a genuine fire risk, so clear it first.

Why your dryer runs but will not heat
- A blown thermal fuse. This safety fuse cuts the heat when the dryer overheats, and it overheats when the vent is clogged with lint. A blown fuse is a common cause of no heat, and it is a warning that the vent needs clearing.
- A failed heating element (electric dryers). The element is the coil that produces heat. When it burns out, the dryer runs normally but stays cold.
- A bad igniter or gas valve (gas dryers). On a gas dryer, the igniter lights the gas. A weak or failed igniter, or failed gas valve coils, means no flame and no heat.
- A worn thermostat or thermistor. These tell the dryer how hot to get. When one fails, the dryer may not call for heat at all.
- A clogged vent. This is the root cause behind many of the faults above. Restricted airflow makes the dryer overheat, trip the fuse, and run long without drying.
Gas dryer vs electric dryer: what is different
Both types use the same drum, motor, and airflow, so the mechanical parts fail the same way. The difference is how they make heat. An electric dryer uses a heating element and two 120 volt legs of power, so losing one leg lets the drum spin but kills the heat. A gas dryer burns gas lit by an igniter, so a no-heat gas dryer is usually the igniter or gas valve. Telling a technician which type you have speeds up the diagnosis.
Quick checks before you call
- Clean the lint trap and the vent. A clogged vent is the most common cause, and clearing it sometimes restores heat on its own. If your dryer needs two cycles to dry one load, the vent is the first suspect.
- Check the settings. Confirm you are not on an air-dry or fluff cycle, which runs with no heat on purpose.
- For electric dryers, check the breaker. An electric dryer uses a double breaker. If one half trips, the drum still turns but there is no heat. Reset both.
- Feel the exhaust outside. No warm air at the outside vent while running points to a heat fault or a full blockage.
If it still will not heat, the element, igniter, fuse, or thermostat needs testing, and that is a job for a technician.
Dryer not heating, by brand
Samsung dryer not heating
Samsung dryers most often show no heat from a blown thermal fuse or a failed heating element, frequently after a clogged vent. Many display a heat-related error code that points straight to the part.
Whirlpool dryer not heating
Whirlpool dryers (and the Maytag and Kenmore models on the same design) commonly lose heat at the heating element or the thermal fuse. Check the vent first, since a blocked vent is what usually takes the fuse out.
LG dryer not heating
LG dryers tend to fail at the heating element or a thermistor that misreads the temperature. LG units often flag a diagnostic code you can read before the technician arrives.
GE dryer not heating
GE dryers most often lose heat at the heating element or a failed thermostat. As with every brand, a clogged vent is a frequent underlying cause.
How much does it cost to fix a dryer that will not heat?
| Repair | Typical cost |
|---|---|
| Thermal fuse | $100 to $200 |
| Heating element (electric) | $150 to $300 |
| Igniter or gas valve (gas) | $150 to $300 |
| Thermostat or thermistor | $100 to $250 |
| Vent cleaning | $120 to $250 |
Most no-heat repairs land between $100 and $300. See our dryer repair cost guide and the Michigan appliance repair cost guide for the full breakdown.
Why a no-heat dryer can be a fire risk
The clogged vent behind so many no-heat dryers is not just an inconvenience. Restricted airflow traps heat and lint, and clogged dryer vents cause thousands of house fires every year. If your dryer takes two cycles to dry one load, gets hot to the touch, or smells of burning, stop using it and get the vent cleared. Clearing it removes the hazard and often brings the heat back at the same time.

Frequently asked questions
Why is my dryer running but not heating?
Usually a blown thermal fuse (from a clogged vent), a failed heating element on an electric dryer, or a bad igniter on a gas dryer. A worn thermostat can also stop the dryer calling for heat.
How do I know if it is the heating element or the thermal fuse?
Both kill the heat, but a blown thermal fuse usually follows a clogged vent, and the fuse is the cheaper part. A technician tests both in minutes to confirm which one failed.
Why is my dryer not heating even though the vent is clear?
Then the likely cause is the heating element on an electric dryer, the igniter or gas valve coils on a gas dryer, or a failed thermostat or thermistor.
How much does it cost to fix a dryer that will not heat?
Most no-heat dryer repairs run $100 to $300 in Michigan. A thermal fuse is about $100 to $200, and a heating element or igniter is $150 to $300.
Is a dryer that will not heat a fire risk?
The clogged vent behind many no-heat dryers is a genuine fire risk. Clearing it removes the hazard and often restores heat at the same time.
Can I fix a dryer not heating myself?
You can clean the lint trap and vent, which sometimes restores heat. Replacing the element, igniter, or fuse involves the electrical or gas system and is safer left to a technician.
