Allight, it's winter, there's snow... We have a 2 and a half car garage... Both had openers, the one on my side's had a dead motor for a few years...
I bought a garage door opener for my side of the garage. Now, the one on my moms side's refusing to work correctly (i think it's jelious

)
It had this problem a few times last year, but only when it got uber cold (20 degrees or colder) It's now 35 degrees, and hers doesnt work.
What happens is that the garage door opener goes down 7/8 of the way, binds up, and refuzes to go past that point. In order for the door to go down, you need to help it down... It goes up just fine.
When I pull the door manually, it goes down fine also...
I think the problem's in the garage door openers track, it kinda flex's as the door's going down... When it gets to a few feet off the ground, the opener's track flex's upwards alot, before it resets.
I've tried greasing the track, tightening the bolts that hold the track together (wimpy 1/4" carrage bolts), and greasing the garage door track....
any other ideas before I burn the damn thing down?
Tks alot
