I have a Craftsman garage door opener and the wall opener will not operate the door. It functions for the remote lockout and the light, but does nothing for the door. It has been working for the last month (we just bought the house), but didn't work today. The LED is flashing a series of about 5 flashes. I've looked in the manual and there is no mention of this in the troubleshooting section.
Anyone have any ideas on what the problem might be or how to fix it?
