When your dryer runs but your clothes stay damp, it’s more than frustrating—it’s a sign something’s wrong. At Col Tech Appliance Services, we often get calls about dryers that stop heating. Thankfully, the problem is usually easy to diagnose.
What are the common reasons a dryer isn’t heating?
- Blown thermal fuse:
This safety device blows if the dryer overheats. Once it’s blown, the heating element won’t work. - Faulty heating element:
If the heating element burns out, your dryer won’t generate heat, even though it still runs. - Malfunctioning thermostat:
The high-limit thermostat helps regulate temperature. If it’s defective, it can prevent the dryer from heating. - Broken igniter (gas dryers):
In gas models, a faulty igniter won’t light the burner, stopping the heat process completely. - Tripped circuit breaker (electric dryers):
Dryers need 240 volts to operate. If one of the two breakers trips, the drum may turn—but won’t heat. - Clogged venting system:
Poor airflow due to lint buildup or a blocked vent can overheat and trigger safety shutoffs.
How do I fix a dryer that won’t heat?
Start by:
- Checking the circuit breakers.
- Cleaning the lint trap and vent.
- Testing the thermal fuse and thermostat (a multimeter helps here).
But remember—working with electrical components or gas lines can be dangerous. When in doubt, it’s best to call a technician.
