Dryer Problems: Every Symptom and What It Means
Not heating, too slow, will not start, loud, smelly or shutting off. Find your symptom, see the likely cause, and go straight to the full guide.

Most dryer problems fall into six groups: no heat, slow drying, will not start, noise, a burning smell, and stopping mid-cycle. Airflow causes more of them than any single part, so clean the lint screen and check the vent first. A gas smell or any smoke is an emergency: leave the house and call 911.
Key takeaways
- Six symptoms cover most dryer calls. Find yours in the table below.
- A blocked vent causes many of them, so check airflow before replacing parts.
- Gas smell, smoke or flames are emergencies. Leave the house and call 911.
- Each symptom below links to a full guide with checks, costs and FAQs.
Find your symptom
Start with what the dryer is doing, then open the matching guide.
| What the dryer is doing | What it usually means | Full guide |
|---|---|---|
| Runs but the clothes stay cold or damp | A heat failure: breaker, thermal fuse, thermostat, element or igniter | Dryer not heating |
| Clothes need two cycles | Restricted airflow in the lint screen, vent or outside flap | Takes too long to dry |
| Nothing happens, or it hums and will not spin | Power, door switch, start switch, thermal fuse or a seized part | Won’t start |
| Squeals, thumps, grinds or rattles | A belt, pulley, roller, bearing or a loose object | Noisy dryer repair |
| Smells like burning or hot dust | Lint scorching, a slipping belt, wiring or a motor overheating | Dryer smells like burning |
| Stops before the cycle ends | Overheating, door switch, moisture sensor or thermal fuse | Dryer stops mid-cycle |
| A code appears on the display | A part fault or restricted airflow, depending on the brand | Dryer error codes |
| It stopped working after a power outage or surge | A tripped breaker, one half of a double breaker off, or electronics that need a reset | After a power outage or surge |
| It starts and stops by itself | A worn door switch, a loose connection or a control fault | Dryer stops mid-cycle |
What is the most common dryer problem?
A restricted vent is the most common, and it shows up as slow drying, overheating and thermal fuses that keep blowing. After that come heating failures such as a burned-out element or a failed igniter, then worn belts, rollers and door switches.
Not heating
The drum spins, the air stays cold. On an electric dryer, check both halves of the double breaker, then suspect the thermal fuse, thermostat or heating element. On a gas dryer, the igniter glowing with no flame usually points to the gas valve coils.
Read the dryer not heating guide.
Taking too long to dry
If clothes need two cycles, the vent is the first suspect. Lint in the duct, a crushed foil run or a stuck outside flap traps humid air in the drum. The ten-minute vent test tells you whether it is the vent or the dryer.
Will not start
A dead dryer points to power: the breaker, the cord, the door switch or the start switch. A hum with no spin points to the motor or a seized drum roller or pulley. Turn off a humming dryer rather than keep trying.
Making noise
The sound tells you the part: squeals are usually the idler pulley or belt, thumps are drum rollers, grinding is a bearing, and rattles are often a coin or zipper.
Smells like burning
Stop the dryer and unplug it. Hot dust usually means lint on the heater, rubber means a belt, and a sharp plastic smell points to wiring or the motor. A rotten-egg smell means gas: leave the house and call 911 and Atmos Energy.
Stops mid-cycle
A dryer that stops and runs again after cooling is usually overheating, often from blocked airflow. A cycle that ends early with damp clothes can be a dirty moisture sensor, and a door that does not latch can stop it within seconds.
Read the stops mid-cycle guide.
Which problems are safety issues?
| Sign | What to do |
|---|---|
| Smell of gas | Leave the house, avoid switches, call 911 and Atmos Energy at 866.322.8667 |
| Smoke or flames | Keep the door closed, leave the house and call 911 |
| Burning smell, no flames | Stop the dryer, unplug it, and call a technician before using it again |
| Breaker that keeps tripping | Stop using the dryer and have it inspected |
| Grinding or scraping | Stop using it: metal on metal can overheat and damage the dryer |
Which dryer problems are dangerous?
A smell of gas, any smoke or flames, a burning smell, a breaker that keeps tripping, and grinding or scraping are all reasons to stop using the dryer. A blocked vent is also a hidden risk, because lint is fuel and restricted airflow makes the dryer hotter.
Quick checks that solve many problems
- Empty the lint screen and wash it with soap and water a couple of times a year
- Check that both halves of the double breaker are on (electric dryers)
- Run the dryer empty for ten minutes and feel the air at the outside vent hood
- Check that the door latches firmly and the drum is not overloaded
- Look for a coin, zipper or key in the drum if you hear a rattle
How can I tell if it is the vent or the dryer?
Run the dryer empty on high for about ten minutes, then feel the air at the outside vent hood. Strong, warm air that pushes the flap wide open means the vent is clear and the problem is in the dryer. A weak trickle means the vent is restricted.
Which dryer problems can I check myself?
Safe checks include the breaker, the lint screen, the outside vent hood, the door latch, the load size and loose objects in the drum. Opening the cabinet, testing electrical parts, and anything involving gas should be left to a technician.

When is a dryer problem not worth repairing?
Small parts on a dryer under about 10 to 12 years old are usually worth fixing. A major part on an older dryer, a rusted drum, or a repair that nears half the price of a comparable new dryer often points to replacing it.

Frequently asked questions
What are the most common dryer problems?
The most common are a restricted vent that causes slow drying and overheating, heating failures such as a blown thermal fuse, burned-out element or failed igniter, worn belts and rollers that make noise, and door or start switch faults that keep the dryer from starting.
Why is my dryer not working?
Start with the basics: the breaker (both halves on an electric dryer), the plug, the door latch and the control lock. If those are fine, the cause depends on the symptom. Use the table at the top of this page to find the right guide.
Should I repair or replace my dryer?
If the dryer is under about 10 to 12 years old and the repair is a small part, repair usually wins. If the repair nears half the price of a new dryer, or the drum is rusted, replacing may be smarter. The repair or replace guide walks through it.
How do I know if my dryer problem is serious?
Gas smell, smoke, flames, a burning smell, a tripping breaker and grinding noises are serious and mean you should stop using the dryer. Slow drying and small noises are less urgent, but they often point to a vent problem that raises fire risk over time.
How much does it cost to fix a dryer in Plano?
Most repairs run about $150 to $400 in the Plano area, parts and labor included. Clearing a vent is usually the cheapest, and motors and control boards cost the most. These are estimates, so ask for the exact price in writing before any work starts.
Can a blocked vent cause many different problems?
Yes. Restricted airflow can cause slow drying, overheating, a blown thermal fuse, a burning smell, noise from the blower and mid-cycle shutoffs. That is why checking the vent is the first step in most of the guides here.
