The drum spins. The buzzer sounds. You open the door and pull out a pile of clothes that feel warm and damp, like they just came out of a steamy bathroom. You run another cycle. Same thing.

A dryer that's not heating is one of the most common appliance problems, and it often has a simple fix. Many cases come down to a clogged vent or a tripped breaker. Others need a part replaced, like a thermal fuse or heating element.

This guide walks you through the checks in order, from easiest to hardest, so you don't spend money on a repair you don't need. If you'd like help from a pro at any point, our dryer repair service is available 24/7.

First, Is Your Dryer Gas or Electric?

This matters, because the two types heat in different ways.

Electric dryers use a heating element, like a big coil. They plug into a thick, three- or four-prong outlet and need a 240-volt power supply.

Gas dryers use a burner and an igniter. They plug into a regular outlet and also connect to a gas line.

Not sure which you have? Look at the plug and the back of the machine. A gas line means gas. A thick cord with a large plug means electric. Your model sticker also tells you.

6 Quick Checks Before Anything Else

Start here. These fix more dryers than you'd expect.

1. Check the cycle setting. Make sure it isn't set to "Air Fluff," "No Heat," or a very low temperature. It sounds silly, but it happens to everyone.
2. Clean the lint filter. Pull it out and remove all the lint. Then wash it with warm, soapy water and a soft brush. Dryer sheets leave a thin film that blocks air. A quick test: pour a little water onto the dry screen. If it pools instead of draining through, the film is blocking the mesh.
3. Check the circuit breaker (electric dryers). Electric dryers use a double breaker. Sometimes only half of it trips. The drum still spins, but there's no heat. Flip the breaker fully off, then on again.
4. Check the gas valve (gas dryers). Make sure the gas shutoff valve behind the dryer is open. Check that other gas appliances in your home are working.
5. Look at the vent outside. Run the dryer, then go outside. You should feel strong, warm air and see the flap open wide. Weak airflow means a blockage.
6. Don't overload the drum. A packed dryer can't circulate air. Try a smaller load.

If none of that helps, move on to the causes below.

How Much Does Appliance Repair Cost?

Common Causes of a Dryer Not Heating

1. A Clogged Lint Filter or Vent

What happens: Hot, wet air needs a clear path out. When lint blocks it, heat builds up, and the dryer's safety parts shut the heat off. Clothes stay damp, and the machine may feel very hot on top.

Clues:

• Clothes take two or more cycles to dry
• The dryer top or door feels very hot
• A musty or "hot lint" smell
• The outside flap barely moves

Fix: Clean the lint filter every load. Pull the dryer away from the wall and check that the duct isn't kinked or crushed. Clean the full length of the vent hose and the outside hood. Do this at least once a year.

This is also a fire risk, so don't skip it. Lint is highly flammable.

2. A Tripped Breaker or Low Power

What happens: Electric dryers need two live lines of power for heat. If one side drops, the motor can still run, but the heating element gets nothing.

Clues:

• The drum spins, but the air stays cool
• The breaker looks "on" but feels loose
• Lights or other appliances flicker on the same circuit

Fix: Reset the double breaker. If it trips again, stop. That can signal a short or a failing part, and a technician should check it.

3. A Blown Thermal Fuse

What it is: A small safety fuse that cuts power to the heat if the dryer gets too hot. When it blows, the dryer often still tumbles, but won't heat.

Clues:

• The drum turns, but there's no heat
• Sometimes the dryer won't turn on at all
• It follows a period of overheating or a clogged vent

Fix: The fuse itself is cheap, but it blows for a reason. If you replace it without fixing the vent, it may blow again. A technician can test it and find the cause.

4. A Failed Heating Element (Electric Dryers)

What it is: The coil that creates heat. Over time, it can crack or burn out.

Clues:

• The dryer runs, but the air is cool or only slightly warm
• The breaker and the vent are fine
• The dryer is several years old

Fix: The element needs testing with a meter, and then replacing. This requires working with high-voltage power, so it's a job for a professional.

5. A Bad Igniter or Gas Valve Coils (Gas Dryers)

What it is: The igniter glows to light the gas. Coils on the gas valve open it. When either wears out, the burner doesn't light.

Clues:

• The drum runs, but you never smell or hear the burner start
• You see no glow through the burner tube (don't open the machine to look)
• The dryer is older and gets heavy use

Fix: These are gas parts, so leave this to a technician. If you smell gas at any time, leave the home and call your gas utility from outside.

6. A Faulty Thermostat

What it is: The thermostats and thermal cutoffs control how hot the dryer gets. If one fails, the dryer can heat too little, too much, or not at all.

Clues:

• Heat that cycles on and off oddly
• Clothes that come out too hot or still damp
• No heat, but power seems fine

Fix: A technician can test each one and replace what's bad.

7. A Bad Timer, Control Board, or Selector Switch

What it is: The parts that tell the heater when to turn on. If they fail, the signal never gets sent.

Clues:

• Heat only works on certain settings
• The display acts odd, or buttons don't respond
• Everything else seems fine

Fix: These need testing by a pro. Replacement can cost more, so it's worth getting a clear diagnosis first.

What If the Dryer Heats, But Clothes Stay Damp?

That's a related, but different problem. The heat is working, but the moisture isn't leaving.

Most often, it's still airflow. Check the lint filter and vent again. Other causes:

• The washer isn't spinning out water. If clothes go in soaking wet, the dryer struggles. Check your washer's spin cycle.
• Too big a load, or too many heavy items like towels and bedding
• A worn drum seal or belt, which lets air or heat escape
• A long or bent vent run, which slows air out

What Not to Do

• Don't run the dryer if the vent is clogged. It's a fire hazard.
• Don't open the back of a plugged-in dryer. Always unplug it first.
• Don't bypass a thermal fuse. It's a safety device. Skipping it can cause a fire.
• Don't ignore a gas smell. Leave, and call the gas company.
• Don't keep resetting a breaker that keeps tripping. Something's wrong.
• Don't use a vent hose made of thin plastic or foil. Use the type your dryer's maker recommends.

Signs It's Time to Call a Pro

Call a technician if:

• You've done the six quick checks, and there's still no heat
• The breaker keeps tripping
• You smell gas or something burning
• Clothes come out scorched or the dryer is too hot to touch
• The dryer has been overheating
• The control panel or buttons act strange
• You aren't comfortable working near power or gas

Repair or Replace?

If your dryer is under 8 to 10 years old, repair is often the better choice. A thermal fuse, an element, or an igniter usually costs far less than a new machine. If it's older, needs several parts, or the repair costs close to half the price of a new one, replacing it may make more sense.

Frequently Asked Questions

Q: Why is my dryer running but not heating?
A: Common causes are a clogged lint filter or vent, a tripped breaker, a blown thermal fuse, a failed heating element, or a bad igniter on gas dryers.

Q: How do I know if my dryer's heating element is bad?
A: The drum spins but the air stays cool, and the breaker and vent are fine. A technician can confirm it with a meter test.

Q: Why does my electric dryer have no heat but still spins?
A: Often one side of the double breaker has tripped, or the heating element or thermal fuse has failed.

Q: Can a clogged vent stop my dryer from heating?
A: Yes. Blocked airflow makes the dryer overheat, and the safety parts shut the heat off. It's also a fire risk.

Q: How often should I clean the dryer vent?
A: At least once a year. Clean it more often if you have long vent runs, pets, or heavy laundry loads.

Q: Is it safe to replace a thermal fuse myself?
A: Many people do, but the fuse usually blows for a reason. If you don't fix the cause, it may blow again. It's often best to have a technician check.

Q: Why is my gas dryer not heating?
A: Check that the gas valve is open. If it is, the igniter or gas valve coils may be bad. Leave those repairs to a pro.

Q: Is a dryer that won't heat worth fixing?
A: Often yes, especially if it's under about 10 years old. A technician can give you an estimate before you decide.

Final Thoughts on a Dryer Not Heating

When a dryer stops heating, the cause is often simple: a clogged filter, a blocked vent, or a tripped breaker. Start with the six quick checks. They cost nothing and fix many cases.

If those don't help, don't force it. Heating parts and gas lines need proper testing, and a blocked vent is a real fire risk. Reliable Appliance Service is available 24/7 at (844) 332-1026.
