How to replace Control Panel. We first I turned the power breaker off to kill the power. Took the six screws out that holds the panel to the door out. There is a cover over the control board, just unlatch it. I then unlatch the the door latch. I did check the micro switches with a meter to make sure that they functioned properly. The control board was next, just unlatch it. Even though it marked I did use my phone aND took pictures of how all the wires hooked up. Carefully unplugged all the wires. I took the control board out of the piece it snaps in to check it for possible signs of hot spots or damage, it looked good. We'll that was pretty much it, just reassembled it all on the new control panel, put the assembly back on the door, turned the power back on and wha la, it worked.
