Suzan F Lexington , NC November 17, 2015 Appliance: KitchenAid Refrigerator KBFA20ERSS00 Kitchenaid Refrigerator Kbfa20erss00: Buttons on control panel did not work some parts missing. How to replace Cover, Lwr Hinge (Blk). We turned off the circuit breaker. We then removed the light cover and then the control panel. We disconnected the Keyboard, Utah, plugged in the new one and turned the breaker on to see if everything worked. We realized that we did not need a new jazz board so that is being returned. The old Keyboard was removed, the new one attached and all the parts were put back. The frig works fine now at the recommended settings of zero and 38F. 21 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
