John C West Nyack , NY January 31, 2015 Appliance: KitchenAid Gas Slide In Range KGST307HBS9 Kitchenaid Range Kgst307hbs9: Original control board fried received replacement from app in 2 days easy install except i kept getting a f1 e3 error code after installing the new board and completing the end of service test proc. How to replace Control Board. Called your 877 number and discussed the issue with Sharon R. who emailed a tip sheet to me within minutes. The #1 tip was to double check then P1 connector ribbon. Removed and reinstalled P1 connector until it "clicked" and presto zappo F1E3 code cleared. High Five to Sharon R. for her courteous, prompt and ACCURATE assistance. Kudos to APP for inventory, service and price. 7 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
