Frederick S Whittier , CA August 31, 2015 Appliance: KitchenAid 30" Slide-In Range Designer Style Convection Oven KGSC308LSS0 Kitchenaid Range Kgsc308lss0: Kitchenaid superba oven display blank. How to replace Control Board. Oven display began flickering, then fading to completely black, but still functioned for some time. When oven was on broil or high heat for too long the display would flicker back on, and enter commands on its own. Even went into Self Clean mode while something was baking, and locked the oven door (very dangerous). New control board took about 10 minutes to replace. Just a few screws beneath it, and a few wire-harness plugs to unplug and plug back in on the new unit. The plugs each only fit in one place, so you can't accidentally mess anything up. Once the unit came back on, the display lit up brightly, but displayed an f1-E3 error. Some quick googling found the following fix...which I didn't think would work, but did. STEP 1 Unplug the unit and wait 5 seconds. STEP 2 Plug back in and wait 5 seconds. STEP 3 Press the following keys: >CONV. BROIL >CLEAN >BAKED GOODS >Enter 190 >TIMER SET STEP 4 Press START 12 Times STEP 5 Make sure Timer ID is the same as the oven. STEP 6 Press CANCEL to exit. 25 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
