Quick answer
A dryer that tumbles but will not heat usually has a blocked vent, one leg of its double breaker tripped (electric), a closed gas valve (gas), or a failed part: the thermal fuse, heating element, igniter or a cycling thermostat. Clean the lint screen, check airflow at the outside vent, reset the breaker and confirm the gas valve is open. If it still runs cold, an appliance technician tests the fuse, element and thermostats; typical dryer repairs run $100–$430 (Angi). Call (888) 217-0236 to reach an appliance repair company taking calls in your ZIP; the line is answered 24/7.

A dryer that tumbles but stays cold almost always has one of a short list of faults, and the most common one is not a part at all: a lint-packed vent that makes the dryer overheat until a safety fuse cuts the heat. That is why the first check is the vent, and why a dryer that "fixes itself" after a rest is a warning rather than good news.
Check These First (15 Minutes)
- 1Clean the lint screen and look at the vent hood outside. Run the dryer and feel the outside flap. Weak or no airflow means the duct is blocked, crushed behind the machine or full of lint.
- 2Check the breaker on an electric dryer. An electric dryer runs on two breakers tied together. If one half trips, the drum still turns but the element gets no power. Reset the double breaker fully off, then on.
- 3On a gas dryer, check that the gas valve behind it is open. The handle should run along the pipe. If you smell gas, stop, leave the house and call the gas utility from outside.
- 4Try a timed dry on high heat. Some auto-dry and sensor cycles end early when the sensor bars are coated with dryer-sheet residue; wipe them with rubbing alcohol.
What Usually Fails
| Symptom | Likely cause | Who fixes it |
|---|---|---|
| Drum turns, no heat at all, electric | Blown thermal fuse, failed heating element, one breaker leg tripped | Appliance technician (after you check the breaker) |
| Drum turns, no heat, gas | Igniter, flame sensor or gas valve coils | Appliance technician |
| Heats a little, takes two or three cycles | Restricted vent, failing cycling thermostat | Vent cleaning first, then a technician |
| Heat comes back after the dryer cools down | High-limit thermostat tripping because the vent is blocked | Clear the vent; have the limit checked |
| Burning smell or scorched clothes | Lint near the heater, failing element | Stop using it and call a technician |
A thermal fuse is cheap, but replacing it without clearing the vent only buys a few loads before it blows again. A technician will usually test the fuse, element and thermostats with a meter and look at the duct before ordering parts.

Why the Vent Matters
The U.S. Fire Administration's report on clothes dryer fires in residential buildings (2008 to 2010) found that failure to clean was the leading factor in dryer fires, at 34 percent. A dryer that has started losing heat because of lint is a dryer running hot inside the cabinet.
What a Repair Costs
Angi puts typical dryer repairs at $100–$430, about $180 for the average job, with technician labor at $40–$120 an hour plus parts. The dryer repair page has the full table with sources. Older dryers with a failed element and a worn drum bearing at the same time are where replacement starts to make more sense than repair.
When to Call

Frequently Asked Questions
Why is my dryer spinning but not heating?
On an electric dryer the usual causes are a tripped breaker leg, a blown thermal fuse or a failed heating element. On a gas dryer it is usually the igniter, flame sensor or gas valve coils. A blocked vent is behind many blown fuses.
Can a clogged vent stop a dryer from heating?
YesRestricted airflow makes the dryer overheat, the high-limit thermostat cuts the heat, and repeated overheating blows the thermal fuse.
How much does it cost to fix a dryer that won't heat?
Angi puts typical dryer repairs at $100–$430, about $180, with labor at $40–$120 an hour plus parts. A fuse is at the low end; an element or gas valve is higher.
Is a dryer that is not heating dangerous?
It can be. Lint build-up is the leading factor in dryer fires, so stop using a dryer that smells of burning or scorches clothes and have the vent cleared.
