I installed our garage door almost three years ago and it's worked
fine until recently. In recent months, it's been acting like the
panels are getting out of alignment and it binds up and reverses
direction. I need to find the manual to see if there's a sensitivity
adjustment. We're about 18'' behind in rainfall this year and we did
put piers on the back of the house when we first moved it so it's
possibly the house has shifted.

Sound reasonable???
