Joanne M Boynton Beach , FL April 04, 2016 The knob on the dryer spun around the eventually came off completely I was going to call a repairman, then I thought it would cost too much, should I just replace the dryer? I looked at the knob, there was a small crack, I Googled dryer parts and came up with AppliancePartsPros.com, found my part and ordered it, hoping for the best. Installed the new knob, and BAM, it was fixed in less than 10 seconds! And for about $24 (including shipping). Dryer works fine, thank you very much! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
