Most Frequent Causes for Dryer won't start
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.

I have replaced the dryer switch timer and it keeps going out what would be the problem

FishGrl28S, it might not be the timer. It could be the timer KNOB. Sometimes the knob will crack where it slides onto the timer shaft. When you turn the knob, the timer shaft doesn’t turn. It remained in the off position. The knob is pointing to the cycle so it looks like your in a dry cycle but you actually still on OFF. This is common with many GE dryers.

I have 3 different dryers and none of them all of a sudden won't start there is no power to start button what do I do

You need to make sure you have proper voltage and polarity at the wall outlet. If you know how to use a multimeter then you can check the voltage yourself. Or, have an electrician test them. That would be the first thing to do.

So, if you dryer switch is sticking and sometimes won’t move, how to replace the part? The dial eventually turns to selected dryer selection, but when it finally stops, how to replace it?
