Dryer Not Heating? Common Causes and Solutions
Your dryer tumbles but clothes stay wet. Learn the most common reasons dryers stop heating and what to do about it.
A dryer that tumbles but does not heat leaves you with wet clothes and wasted time. The cause depends on whether you have an electric or gas dryer.
Electric Dryer No-Heat Causes
The heating element burns out over time and is the most common cause of no heat in electric dryers. The thermal fuse is a safety device that blows when the dryer overheats, usually due to a clogged vent. A failed cycling thermostat can prevent the heating element from turning on. A broken timer or control board may skip the heating portion of the cycle.
Gas Dryer No-Heat Causes
The igniter glows but gas does not ignite -- this usually indicates failed gas valve coils, a common wear item. A cracked igniter may fail to glow hot enough to open the gas valve. The flame sensor may be dirty or failed, preventing the gas valve from staying open. As with electric dryers, a blown thermal fuse cuts power to the gas valve circuit.
Check the Vent First
Before assuming a component has failed, check the dryer vent. A clogged vent restricts exhaust airflow, causes the dryer to overheat, and blows the thermal fuse. Disconnect the vent from the back of the dryer and run the dryer briefly. If it heats, the vent is the problem. Clean or replace the vent line and the thermal fuse.
When to Call a Pro
If the vent is clear and the dryer still does not heat, a component has failed and needs replacement. PCG Climate repairs gas and electric dryers throughout the East Bay with same-day service available.
