Dryer Not Heating? Gas and Electric Causes
The drum turns, the clothes stay wet. The cause depends on whether your dryer runs on gas or electricity, and very often on the vent.Last updated November 12, 2026 · Written for Brandon, FL households
For an electric dryer, check the double breaker first, then clean the lint screen and vent. Common failed parts are the heating element and the thermal fuse. For a gas dryer, check that the gas valve is open, then look at the igniter. A blocked vent often causes the overheating that blows the fuse, so clear it before replacing parts.
First, gas or electric?
Electric dryers plug into a large 240-volt outlet and heat with a coil element. Gas dryers plug into a standard outlet and have a gas line behind them. The parts that fail are different, so check which you have.
Electric dryer with no heat
- Check the breaker. It's a double breaker, and one half can trip so the drum turns but there's no heat. Turn it fully off, then on.
- Clean the lint screen and check the vent for airflow outside.
- If there's still no heat, the usual failures are the heating element, the thermal fuse or the high-limit thermostat. A technician tests these with a meter.
Gas dryer with no heat
- Make sure the gas valve behind the dryer is open. The handle should line up with the pipe.
- Clean the lint screen and check the vent.
- Look through the small window or panel if your model has one. An igniter that glows but no flame follows often means weak gas valve coils. No glow at all can mean the igniter or a fuse.
- If you smell gas at any point, stop. Leave the house and call 911 or the gas company from outside.
Why the vent matters
A blocked vent makes the dryer overheat, which blows the thermal fuse. If you replace the fuse without clearing the vent, the new one blows too. The U.S. Fire Administration also links uncleaned lint filters and vents to a higher risk of dryer fires. Clean the vent, not just the screen.
When to call a technician
Call once the breaker, vent and gas valve check out and there's still no heat, or if you smell burning. See dryer repair in Brandon.
Common questions
Why does my dryer heat sometimes and not other times?
On gas dryers, failing gas valve coils often cause heat that starts and stops. On electric dryers, a heating element can break intermittently, or a cycling thermostat may be failing.
Is it safe to keep using a dryer that won't heat?
Running it without heat is generally not dangerous, but find the cause. If the cause is a blocked vent, the dryer is overheating, and that is a fire risk.
Can I replace a thermal fuse myself?
Some people do, but a blown fuse is a symptom. Without fixing the airflow problem behind it, the new fuse will blow again.
