Quick answer
If your dryer tumbles but produces no heat, the most common causes are a clogged dryer vent, a tripped breaker (electric dryers need 240V — half the breaker can trip), or a failed heating element, thermal fuse, or thermostat. Check the vent and breaker first; anything involving disassembly or gas lines calls for a technician.
The 7 most common causes
1. Clogged dryer vent (most common). Lint buildup in the vent hose or exterior vent restricts airflow, and modern dryers shut off the heat as a safety response. Pull the dryer out, disconnect the vent hose, and clear lint from the hose and the exterior vent cap.
2. Tripped circuit breaker — check both. Electric dryers run on 240 volts across two breakers. One can trip while the other holds, so the drum spins but the heating element gets no power. Flip both dryer breakers fully off, then back on.
3. Blown thermal fuse. This one-time safety fuse blows when the dryer overheats (often because of a clogged vent). It’s inexpensive but lives inside the machine — and the root cause of the overheating needs addressing too.
4. Failed heating element. The coil that produces heat can burn out, especially in dryers over 8–10 years old. Symptom: everything works, zero heat, vent and breaker are fine.
5. Bad thermostat or thermistor. These sensors regulate temperature. When they fail, the dryer may run cold or shut down mid-cycle.
6. Gas supply issue (gas dryers). Check that the gas valve behind the unit is open. Anything beyond that — igniter, gas valve solenoids, flame sensor — involves gas and belongs to a professional.
7. Control board failure (less common). If none of the above applies, the electronic control may not be sending power to the heat circuit.
Safety notes
Always unplug an electric dryer (or shut off the breaker) before removing any panels. Never work on gas lines yourself — if you smell gas, leave the area and call your gas utility. Clean your vent system at least once a year; restricted vents are a fire hazard.
When to call a pro
If the vent and breaker check out, the fix usually requires opening the machine and testing components with a multimeter. That’s a same-day job for a technician — most dryer heating repairs are completed in a single visit.
FAQ
Why does my dryer take two cycles to dry?
Usually restricted airflow (clogged vent) or a weakening heating element. Start with the vent — it’s the cause more often than not.
Is it worth repairing a 10-year-old dryer?
Often yes — heating element and thermostat repairs typically cost far less than a new dryer.
Can a clogged vent really stop the heat?
Yes. Dryers monitor temperature and airflow; restricted vents trigger thermal safeties that cut the heat to prevent fires.
