Dryer is Not Heating: Find Out Why Your Dryer Stopped Heating
If your dryer is running but not heating, the most likely culprit is a blown thermal fuse, which trips when the dryer overheats and often means your vent is restricted; test the fuse with a multimeter and check the exhaust vent before replacing it. Next most likely issues include a faulty drive motor or its centrifugal switch, which can let the drum run without enabling the heat cycle, and on gas models a failed gas valve solenoid that will stop gas flow even if the igniter glows. Also double-check the cycle and heat setting since a no-heat option or wrong program is an easy miss. A bad igniter is another common failure on gas dryers and can be tested for continuity. If you need parts, enter your model number at RepairClinic.com to find the exact replacement parts for your dryer. This covers both electric and gas dryers and gives you the logical checks and parts to replace so you can get your dryer heating again without guessing.
01 - Dryer Thermal Fuse
The thermal fuse is a safety device designed to protect the dryer from overheating. The fuse is located on the blower housing or at the dryer’s heat source such as the heating element on electric dryers or at the burner on gas models. The fuse should be closed for continuity meaning it has a continuous electrical path through it when good. If overheated the fuse will have no continuity meaning the electrical path is broken and the fuse has blown. A multimeter can be used to test it for continuity. Be aware that a blown thermal fuse is an indication of a restricted exhaust vent from the dryer to the outside. Always check t...

02 - Dryer Drive Motor
Most dryer drive motors have a centrifugal switch that energizes a start winding when the motor is first started and closes a heat cycle contact to allow the heat source to work. If the motor's centrifugal switch is faulty, either the motor won’t run or the motor will run but the dryer won’t heat. Since most centrifugal switches are not sold separately, the entire motor will need to be replaced if the switch is defective.

03 - Dryer Gas Valve Solenoid
Gas dryers have two or more gas valve solenoid coils. The gas valve solenoids open the gas valve ports to allow gas to flow into the burner assembly. If a gas valve solenoid fails, the dryer won’t heat. To determine if one or more of the gas valve solenoids has failed, check the igniter. If the igniter glows and goes out but does not ignite the gas, the gas valve solenoid is defective. If one or more of the gas valve coils are defective, we recommend that you replace them as a set.
Highly Likely
04 - Incorrect cycle settings
Ensure the dryer is set to the appropriate heat setting. The setting may have been inadvertently changed to a non-heat option.
Highly Likely
05 - Incorrect cycle selected
The dryer setting may have been inadvertently changed to a non-heat option. Confirm the dryer is set to a proper heating option such as "Regular" or "Heavy" to see if that improves drying performance.
Highly Likely
06 - Dryer Igniter
The igniter uses heat to ignite the gas in the burner assembly. If the igniter is not working, the gas will not ignite, preventing the dryer from heating. To determine if the igniter has burned out, use a multimeter to test the igniter for continuity. If the igniter does not have continuity, replace it.
Highly Likely
07 - Dryer Heating Element
The heating element warms the air before it enters the dryer drum. Over time, the heating element can burn out, causing the dryer not to heat. To determine if the heating element has burned out, use a multimeter to test it for continuity. If the heating element does not have continuity, replace it.
