Common solutions for: Dryer won't start
Solution 1:
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 drye...rs 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.

Door 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 you...r 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.

Solution 4:
Drive 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 prope...rly, 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.

Solution 5:
Belt Switch
On most dryers, when the dryer belt breaks, the motor will still run, but the drum won’t turn. However, some dryers have a switch that shuts off power to the dryer if the drive belt is broken. If this... switch fails, it could shut off power to the dryer even when the belt is not broken. First, start the dryer and then listen for a humming noise. If the dryer makes a humming noise when you try to start it, this indicates that the belt switch is not defective. Next, search for your model number to determine if your dryer has a belt switch. If your dryer has a belt switch, use a multimeter to test the switch for continuity. If the switch does not have continuity, replace it.
