There is nothing more frustrating than a dryer that tumbles for an hour and leaves your clothes still damp. Before you assume the dryer is finished, a few simple checks can solve the problem or at least point to the cause. Here is what to check before you call for dryer repair.
1. Check the Power and Breaker
Many electric dryers need 240 volts to heat, even though they can tumble on 120 volts. If one breaker has tripped or a fuse has blown, the drum may turn without any heat. Check your breaker panel for a tripped double-pole breaker, reset it firmly, and make sure the dryer cord is fully plugged in. If the breaker trips again, stop and call a technician, as this can signal an electrical or heating problem.
2. Clean the Lint Filter and Check the Vent
A clogged lint filter or blocked vent is one of the most common causes of poor heating. Clean the lint screen before every load, and check behind the dryer for a crushed or kinked vent hose. If clothes are taking two or three cycles to dry, airflow may be restricted. Clear lint from the vent opening and make sure the outside vent flap opens freely. Restricted airflow also makes the dryer run hotter than it should, so this check is important for safety as well as drying time.
3. Heating Element, Thermal Fuse, and Thermostat
On electric dryers, heat comes from a heating element controlled by thermostats and protected by a thermal fuse. If the thermal fuse blows, often because of poor venting, the dryer will tumble with no heat at all. A broken heating element or a faulty thermostat can cause the same symptom. These parts sit behind panels and require testing with a meter, so leave this diagnosis to a professional rather than opening the cabinet yourself.
4. For Gas Dryers: Gas Supply and Igniter
If you have a gas dryer, confirm the gas valve behind the dryer is open and that other gas appliances in your home are working. A weak igniter, a faulty flame sensor, or failing gas valve coils can cause the burner to light briefly and then shut off, or not light at all. Because gas and burner parts involve safety controls, do not attempt to repair them yourself. A technician can test the ignition system safely and replace only the failed part.
5. Settings, Moisture Sensor, and Load Size
Sometimes the fix is a setting. Make sure the cycle is set to a heated dry mode rather than Air Fluff or No Heat. Very large or tightly packed loads dry unevenly, so try a smaller load and the Timed Dry setting. Wipe the moisture sensor bars inside the drum with a soft cloth, since fabric-softener residue can fool the sensor into ending the cycle early. If the dryer heats on Timed Dry but not on Auto Dry, the sensor or control may need attention.

Frequently Asked Questions
Why is my dryer running but not heating? The most common causes are a tripped breaker, a clogged vent, a blown thermal fuse, or a faulty heating element, igniter, or thermostat. Airflow and power are the easiest safe checks at home.
Can a clogged vent stop a dryer from heating? Yes. Restricted airflow can overheat the dryer, trip safety devices, and greatly extend drying time. Keep the lint filter clean and the vent clear for safe, efficient drying.
Is it worth repairing a dryer that will not heat? Often, yes. Fuses, thermostats, sensors, and heating elements are common repairs that cost far less than a new dryer. A technician can confirm the cause and give you a clear cost before you decide.
