Joe R Garland , TX March 17, 2017 Appliance: Model AP6021414 Electronic control board went blank but beeped We replaced the control board and it fixed the problem. Replacing took 30 minutes. The only issue was the difficulty pulling the 2 black connectors out from the board. You have to pull hard. There is no need to pull the oven out from the wall. Just remove the 2 screws on the side and gently pull out the control board. However, be careful to remove the ribbon connector or it will crack. Just push in the sides and lift gently. This saved us $2000!!! The part was here in one day! The warranty can't be beat. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
