This is the second time I've had the garage door folks out to look at my door. The issue is that, somewhat randomly, the door will get hung up at the top, and the operator's force sensor, in trying to get it around the curve of the tracks, binds a little and will make the operator think it's hitting something, and back the door into the open position. This is a frustrating thing to happen just as you're leaving for work

I had somebody out last week. Their solution was to turn down the force sensor. While maybe not the best solution, it appeared to have solved it for a few days.

This Tuesday, it happened again, forcing me to shove the garage door down its tracks.

Having the more senior guy out today, he adjusted the tracks slightly, giving the wheels a little more breathing room around the corner. The real problem, however, wasn't the rails.

As he was packing up, the guy apologetically said, "Who was it that did this original work? Tall, skinny guy? Yeah. I sorta mourn this guy's work... take a look at that wiring."

He showed me a series of wires that connected the operator to the laser sensor. "See those? I put on those wire caps. Previously, those were bare wire, and when the rail would vibrate slightly, it would sometimes make contact, making the operator think the laser sensor had been tripped."

I laughed, signed the paper he handed me, and wished him good day. Hope it's fixed.
