Dryer not turning on.

"Cause 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 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.

Cause 2

Start Switch

To determine if the start switch is defective, attempt to start the dryer. If the dryer hums but does not start, the start switch is not at fault. If the dryer does not respond or make any noise, the start switch could be at fault. Use a multimeter to test the start switch for continuity. If the switch does not have continuity, replace it.

Cause 3

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 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."

"Step by step procedure. http://www.repairclinic.com/vwo12

make sure your vent hose is not crimped/plugged, also clean out the vent housing at the end of hose, outside. House fires/plugged dryer vents.

The dryer stays cool by having an UNrestricted air flow thru hose, otherwise parts heat up and fail.

Clean the filter after every load or else you will develop the habit of not cleaning it."

If the dryer won't do anything, the belt may be broken or may have come off of the tension pulley. Either trips the belt switch, which disables the motor. If the motor won't run, the dryer won't heat.
