Whirlpool electric dryer will not start when start knob is pushed

Check and clean your venting from the dryer to the outside. If it is plugged it will trap the moisture in the machine. Remember heat doesn't dry the clothes without air flow to push the moisture out.

that knob is actually a switch. fixing it will be much easier, if you replace the whole switch unit..
good luck..

Mine did that and it was a therostat and the heating element

purchased new clothes dryer. The old one was 6 years old

Dryer door does not think it is closed. There is a sensor on the top of the door that is probably not making contact with the door. Trying pushing the top part of the door and holding it then press the start button.. if the unit starts running then you know what it is. I just had one of these dryers delivered today and had to find out about this by myself tonight!!

Thanks.

try to unplug the dryer for 5-10 minutes this should reset the board. if not take off the bottom panel and test the resistance of the thermistor ( the tech sheet is in the bottom there or up top)

Same problem here, however I can assist the start by rotating the drum while pushing start. May be a capacitor problem???

the door switch is bad. $16.65 Item #
