I have a Craftsman GDO Model 139.18060 with a wireless Keyless Entry Pad which the kids use to enter the house. It is not working. I replaced the battery and pressed the learn button to reset the code. The motor unit clicks once (which I assume accepts the code) but the keyless entry pad lights flash 6 or 7 times. We bought a new keyless entry pad and have the same problem. Could it be the logic board inside the motor unit? We had a power outage last winter and I had to unplug the motor unit overnight before I could reprogram the keyless entry. A few months later the door came down and hit the tongue of the boat trailer. Could this have done something to the motor unit? The sensors are difficult to keep in alignment but the door opens and closes by holding the wall unit down for the duration of the door operation. I have misplaced the remote control units as we don't need them. Any ideas? - my kids are frustrated because they can't get in the house!
