Quick Checks
Check the Lint Filter
A clogged lint filter restricts airflow, which can cause the dryer to overheat and the heating element to shut off. Clean the lint filter before each load.
Check the Dryer Vent
Make sure the vent hose isn't kinked, crushed, or blocked. A clogged vent prevents hot air from escaping, leading to overheating and poor drying. Disconnect the vent and check for obstructions.
Check the Circuit Breaker
Dryers use a lot of power, often on a double-pole breaker. Make sure both breakers are switched on. If one has tripped, reset it.
Common Causes
Clogged Dryer Vent
DIYA severely clogged vent is the most common cause of a dryer not heating. Over time, lint accumulates in the vent hose and the vent duct, restricting airflow. The dryer's high-limit thermostat may be tripping to prevent a fire hazard.
Faulty Heating Element
Call ProThe heating element is responsible for producing heat in an electric dryer. If the element is burned out, the dryer won't heat. This requires testing with a multimeter.
Gas Supply Issues (Gas Dryers)
Call ProFor gas dryers, check that the gas supply valve is open. If other gas appliances aren't working, there may be a problem with the gas supply to your home. A faulty gas valve or igniter can also prevent the dryer from heating.
Failed Thermal Fuse
DIYThe thermal fuse is a safety device that blows when the dryer overheats. If the fuse is blown, the dryer won't heat. This often happens due to a clogged vent. You can test it with a multimeter.
Faulty Thermostat
Call ProThe thermostat regulates the temperature inside the dryer. If the thermostat is faulty, it may not be sending power to the heating element or gas valve.
Control Board Malfunction
Call ProThe control board controls all the dryer's functions. A malfunctioning control board can cause a variety of problems, including no heat. This is more common in newer, electronic dryers.
When to Call a Professional
- If you're uncomfortable working with electricity or gas.
- If you suspect a gas leak. Gas leaks are dangerous and require immediate attention.
- If you've checked the simple things and the dryer still isn't heating.
- If you need help diagnosing the problem or replacing parts.
Safety Warning
Disconnect the dryer from the power supply before attempting any repairs. Gas dryers should have the gas supply shut off before working on them. Never bypass safety devices like thermal fuses.
