It seems that my garage door has broken! Which was not a surprise, really. A couple of months ago, my neighbor across the street was experiencing problems with his garage door. It would act like the pressure sensor was broken and change directions occasionally. Soon after that the spring broke. Given that our houses were built at the same time, it was no surprise when that happened to me. And it looks like the garage door opener almost ripped out the bar off the door from the now extremely heavy door.
