I ordered a new knob and the switch, watched a video online on how to remove and replace it. I did this all by myself, no help from hubby. The hardest part was getting that little tiny screw out that holds the unit in. It couldn't be a regular screw like a Philips head. No it was a six sided screw and very tiny. Anyway, got it out finally and the rest went smoothly. I had originally ordered the wrong knob online. After getting the wrong one I phoned them to make sure I got the right one. I am sure I saved a lot of money by not having the repairman out. GE parts are expensive enough without having to take a mark-up from a service. Thank you Appliance Parts Pros for your help!
