Hi just wanted to know why my dryer keeps shutting off after I push the on button and it will run for few minutes and than it shuts off again or may run for 20 or 30 minutes at a time. When it shut off I keep pushing the button and it want run then again it may for few minutes.
Thanks!

There are several things that can go wrong with a dry but lets start with easy and inexpensive. Pull the dryer out from the wall and disconnected the vent tube. Inspect inside the tube and the dryer to insure you don't have a lint blockage. I suspect this because it sounds like your dryer is overheating and shutting off for safety.
