If your Speed Queen dryer is running but not heating, start with the most likely fixes: a blown thermal fuse is the single most common cause and usually means the exhaust vent is restricted, so test the fuse for continuity with a multimeter and check the vent before you replace it. Next, the dryer drive motor can have a faulty centrifugal switch that lets the motor run but prevents the heat circuit from engaging, and since that switch is usually not sold separately you will likely need the full motor. On gas models, failed gas valve solenoid coils will stop gas flow even if the igniter glows, so replace solenoids as a set if they fail. Also confirm you haven’t accidentally selected a no-heat cycle, since incorrect cycle settings are often the simple culprit. A burned-out igniter is another common failure on gas dryers and can be checked for continuity.

01 - Speed Queen 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...he dryer venting when replacing a blown thermal fuse.

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.
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.
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 - Speed Queen 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.
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.
