My dryer was about two years old when it decided to stop running. I remember putting some clothes in it, closing the door, pressing the start button and going away.
A few minutes, or perhaps hours later, I went back to check up on it just to realize that it was still on. The timer was still showing some crazy number like 50 minutes, the dryer was not running or making any noises, and the clothes were still wet.
Well, perhaps I forgot to press the start button, I remember thinking, so I went ahead and pressed it. It started running, nice! And then it stopped as soon as I released it. So, I pressed it again hoping that this time, it was going to work, but no, it stopped again.
Sounds familiar? You are not alone! It apparently is a very common issue with newer, electronic, dryers.
