My Craftsman Garage Door Opener (139.53976SRT) works fine except for the motion detecting wall control. The remotes and keypad will open the door but the hardwired wall control will not. The indicator light on the control blinks 5 quick times, pauses then binks 5 quick times - continually. The lock switch will work as will the motion detecting light switch. The push button to open the door does not work. What are the blinking lights telling me? The part number of wall console is 41C0472-1. I can ground the bell wire and the door will open and close so it is some fault in the wall console. We had a short power failure prior to this happening.

Thanks
