Most Frequent Causes for Dryer not heating

Cause 1Thermal 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 out. 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 the dryer venting when replacing a blown thermal fuse.

Parts
Thermal Fuse for your FrigidaireDryer
Thermal Fuse - Part # 1489053 Mfg Part # 134120900

Dryer thermal limiter (or thermal fuse). Located on the blower housing. If the dryer overheats, the thermal fuse blows to cut off power to the dryer. If the thermal fuse has blown, the dryer won't start. The thermal fuse cannot be reset--if the fuse has blown, it must be replaced

Cause 2Heating 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.

Heating Element for your FrigidaireDryer
Heating Element - Part # 407685 Mfg Part # 131553900

Dryer heating element and rear housing assembly. Before checking the heating element, first make sure that the thermal fuse is not defective. Normally, a heating element will have a break in the coil if defective.

Cause 3Incoming Power Problem

If your dryer is not heating, then you may have an incoming power problem. Electric dryers need two legs of 120 volts AC equaling 240 volts. It is not uncommon for only one fuse or breaker to trip resulting in the dryer able to run, but not heat. The fuse box or circuit breaker should be checked or voltage measured at the outlet using a multi-meter.

Cause 4High Limit Thermostat

The high-limit thermostat monitors the dryer temperature and shuts off the burner if the dryer overheats. If the high-limit thermostat is malfunctioning, it may shut off the burner even if the dryer is not overheating. However, this is rarely the case. Before replacing the high limit thermostat check all the more commonly defective parts. If you have determined that all of the other components are working properly, test the thermostat by using a multimeter to test it for continuity. If the thermostat does not have continuity, replace it.

High Limit Thermostat for your FrigidaireDryer
High Limit Thermostat - Part # 508516 Mfg Part # 3204267

Dryer high-limit thermostat, L260-70F. If the dryer overheats, this high-limit thermostat will cut off the power to the heating element. If the high-limit thermostat has blown, the dryer won't heat.

Cause 5Main Control Board

The main control board might be defective. However, this is rarely the case. Before replacing the main control board, check all of the more commonly defective parts. If you have determined that all of the other components are working properly, replace the main control board. (The control board cannot be easily tested, but you can try to inspect it for signs of burning or a shorted-out component.)
