Automatic Garage Door problems
When I pushed the button to open the garage door (one day) it was "dead". It did nothing. How do I troubleshoot to see what the problem might be? I had unattached and reattached the wires on the back of the unit on the ceiling thinking there may be corrosion but it turned out to be a problem with the "clicker". But now the door won't open at all with the good clicker or with the button on the wall. There was a spark from the sqrew driver on the sqrew on the ceiling unit before I figured out I had to unplug it first to undo the wires. So maybe a fuse blew?
