In his own words, straight from his Facebook status, "Bartee is now painfully aware of his handyman limitations." This realization came when he tried to install a new sprinkler head in the front yard back in September. It only took 2 days, but he did manage to get the thing to spray water in the coverage area that he selected.

Weeks having passed, and the frustration of that day having dwindled, he attempted yet another homeowner repair. Time to quiet the vibrations in the garage door. He lubricated the chain, tightened some bolts on the hinges and cleaned the sensors. He gloated when it was done, closing the garage door and then asking me if I could hear it. I have to admit, it was barely audible. Success!
Well, not really. The next day when I tried to close the door, it got stuck at the first hinge. By holding the door opener button down, we managed to get the door shut. "Probably I tightened the bolts a little too much", he says. So, some adjustments were made and again the door seems to work. A day or two later, same thing, the door won't close. Since then, I think he loosened the suspicious bolts about 4 different times and still we are having problems shutting the thing.
The new conclusion is that it must have something to do with the sensors. So, today it was time to break out the manual to find out how to adjust the sensitivity. Some more time spent in the garage. Now we've got a garage door that closes 100% of the time on one push of the button,
even if something's in it's path. Not exactly the fix we were looking for. He'll be working on that later this week. :)
I gotta give it to him though. He has the utmost patience with this kind of thing. Although there may be glitches and it will likely take him longer than the average person, he always manages to solve the problem.
