"LOCKED DOOR" light flashing continuously. Door lock is open. Oven door will close. SELF CLEAN will not function but asks me to set timer.If I try to set the BAKE or BROIL function a green "door" light comes on. Nothing functions. A service tech came out, looked at the oven and told me he would have to replace the control board at a cost of $450.00 plus the service call. I opted to try fixing this on my own. Can anyone guide me?
