The PCB (printed circuit board) assembly, also known as the electronic control board, is in the control panel section of the oven. The board helps manage the operation of the oven. If your oven isn’t heating, or has no display, you may need to replace the board. This is the board only; the overlay is not included. The control board measures 14 1/2” L x 5” W. This is a genuine OEM part. Once installed the board can not be returned. Please remember to disconnect the power before starting the repair.
