Steven H Mountain Green , UT September 02, 2014 Appliance: Whirlpool Electric Oven RBD305PDS12 Whirlpool Oven Rbd305pds12: An error code came up indicating the control panel had lost communication with the control board. How to replace Control Panel Assy. W/Membrane Switch (Black Model). I turned off the power, used a lift cart that I could raise up to the height of the oven’s bottom and pulled the oven from the cabinet. I removed the metal cover from the top of the oven and removed the screws securing the control board to the display board and disconnected the ribbon cable from the control board. I had to remove trim from either side of the oven to expose a screw on each side of the control panel holding it in place. I replaced the control panel, attached the ribbon cable and secured the control panel to the control board, replaced the metal cover and slid the oven back into place, restored power. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
