Marshall S Denham Springs , LA March 31, 2014 Control knob loose Pulled retaining clip out from behind knob, had to use needle nose pliars to easily do. Wish a more durable part existed, this is the 3rd or 4th knob I've had to replace. Just cheap plastic used by GE. Easy to replace. 24 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
