Over time, the knob clip and the projection from the start switch broke off. The dryer couldn't start without these parts. I watched a do-it-yourself video from AppliancePartsPros.com and ordered a knob clip assembly and rotary starter switch. I completed the repair all by myself after viewing the video. It was so easy and not intimidating at all! I can't believe I was going to buy a new dryer because I thought it couldn't be fixed.
