Got the model number off the dryer. Looked it up online. I wanted name brand replacement part. Found this wonderful AppliancePartsPros.com. Looked up my model number, went to top control panel section, ordered the Start Switch. In ONE DAY I received it. Removed the back part of my dryer. Easily removed the broken part. (I did watch a video online). Put on the new Start Switch. Instead of ordering a new knob. I removed a knob from the dryer that I don't use. It turns a buzzer on or off to let you know the dryer has stopped. Since I always keep it turned off anyway. I thought I'll use it for the replacement. Otherwise, I could have also ordered a new knob from AppliancePastsPros.com. I am so proud of myself. So for about $25.00 total I fixed it myself.
