I had an appliance repairman come out and he told me for him to replace the timer, knob, and fuse would cost $340 for parts and labor. Plus I already paid him a service charge fee. I decided to fix it myself. Appliance Parts Pros had all the parts I needed and the website showed a video on how to replace the timer. I got the parts for $86. The parts came the same week and it took me 20 minutes to do everything....AWESOME!!!GE
