Spent hours this weekend fighting with garage door. The screws that held the bracket retaining the bar that connects to the torsion springs came out of the wall, and worked its way off the rod. The door suddenly "clunked" when going up, and then wouldn't come down because it torqued sideways. Took a ridiculous amount of time to get the door down so I could work on it, and when we finally got it moving it was so crooked that the top panel had the wheels fall out and it clunked me on the head. Drove me straight down into a fortunately placed chair. I'm glad I have a thick skull because that sucker is heavy. Once the door was down and the fog cleared I had to take the tension out of the torsion springs (for safety as much as anything), disconnect the cables from the door, get the offending bracket back in place and attached to the wall CORRECTLY THIS TIME, get all the wheels back on the door, reconnect the wires and re-tension the springs. It actually wasn't that smooth of a list of activities as access/clearance/patience was a challenge at varying stages, so things progressed in a 2-step forward 1-step back manner. Was also working this around a little dude swim meet, which was mercifully only a mile away, but a lot of back and forth to the pool to watch an event, then run home to mess with door, before running back for next event.
In the end it is working again, and the only lingering effects are a slight bend on the bottom of one side (older son got a little overzealous when prying the door up at one point), a diminished respect for the unknown person who hung the door originally MISSING ALL THE STUDS and a serious goose egg on my head. Really it was a miracle it hadn't slipped free before now, they literally missed every stud with the upper part of the door bracket. We've lived here for over 15 years.
I did manage to make a bunch of pull pin switch kits of all three types during the swim meet...long stretches of sitting around at those things are conducive to busy work activities. People sure do look at me weird when I break out my plastic box of switch making materials and go to work.
