Robert C Cutler Bay , FL February 24, 2015 Appliance: Jenn-Air Refrigerator JS42SEDBDA Jenn-Air Refrigerator Js42sedbda: Removed crisper drawers before turning off unit; shorted the main control board. How to replace Board, Main Display. We were ecstatic that we were able to fix the unit ourselves. We had a Jenn Air suggested appliance repair company come out and tell us that the unit (built in) would not work unless we ordered the crispers ($600 each) and that they were actually discontinued. That meant we'd have to buy a new built in ($8000) which was NOT going to happen. My husband test power in and out on all the components and deduced that it must be just the main control board. We ordered it; it was shipped immediately and it works!!! 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
