Whirlpool dryer stopped working...
I have the Whirlpool Model: WED4900XW0, when I press the start button I hear the click and when I shut the door I also hear the door click. So I am assuming that it's not the door switch or the start button.
"The heating element assembly 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 assembly has burned out, use a multimeter to test it for continuity. If the heating element assembly does not have continuity, replace it.
Heating Element Assembly for your Dryer

Dryer heating element. If your dryer does not heat first check for a blown thermal fuse on the blower housing before replacing the heating element. In most cases the heating element will have a break in the element if defective.
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.
High Limit Thermostat for your Dryer

The heating element on these dryers are garbage. They are about 15 bucks if you get them direct from China, so figure 3-5 years is a pretty good deal. If Whirlpool was really doing a service for their customers, they would include a spare in the original box.
