Gary W Los Angeles , CA March 21, 2016 Appliance: KitchenAid 30" Built-In Electric Double Oven Thermal Convection Self-Clean KEBC208KSS02 Kitchenaid Oven Kebc208kss02: The f2 e0 error code (disconnected keypad) came on once briefly then random beeping after that. How to replace Control Panel Assembly. Installing the new control panel was fairly easy (had to dismount and reattach the main circuit board), and since then the oven has been working perfectly, no random beeps as before. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
