Most Frequent Causes for Dryer won't start

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. 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.

Thermal Fuse for your KenmoreDryer
Thermal Fuse - Part # 2986 Mfg Part # WP3392519

Dryer thermal fuse located on the blower housing. If the dryer overheats, the thermal fuse blows cutting off power to the motor or the heating system. When the fuse is bad the dryer won't start or will run but not heat. The thermal fuse cannot be reset. Fuses often blow due to a clogged dryer vent.

Cause 3Door Switch

The door switch activates when the dryer door is closed. On most dryers, the door switch makes an audible clicking sound when it activates. To determine if the door switch is working, try starting your dryer and then listen for the “click.” If the door switch makes a clicking sound, it is probably not defective. If you don’t hear a click, use a multimeter to use the door switch for continuity. If the switch does not have continuity, replace it.

Cause 4Drive Motor

The drive motor turns the drum and the blower wheel to exhaust the air. Before replacing the motor, first check the thermal fuse, start switch, and door switch. If all of these parts are working properly, but the motor is making a humming noise, remove the belt from the motor and check the blower wheel for obstructions. If the blower wheel is clear of obstructions, the dryer motor might be at fault. If you suspect the motor is defective, replace it.

Cause 5Drive Belt

On most dryers, when the dryer belt breaks, the motor will still run, but the drum will not turn. However, some dryers have a switch that shuts off power to the dryer if the drive belt is broken. Check the dryer belt to determine if it is broken. If the belt is broken, replace it.

Cause 6Incoming Power Problem

If you have a gas dryer, unplug the dryer from the wall and plug something else into the outlet to determine if the outlet is working. If you have an electric dryer, check the home circuit breaker or fuses. If the circuit breaker or fuses are working, use a multimeter to test the outlet.
