The torsion springs are harder to determine if something is wrong with pictures, because of their design.
Do the springs unwind when you raise the door by hand?
You stated it was heavy, so it sounds like one is broken possibly, the wind up and down with the door.
But first. I am not quite sure of the problem as I see different information on its movement, so lets clear that up.
If the door is open all the way. it will move 2 feet towards closed and then reopen, is that correct?
And if the door is closed, it will not move at all, is that correct?
Just need to know the exact issues of both open and closing.
If it will not open the door when closed, how do you get it closed to test?
Did you disconnect the door trolley and then it will open and close normally?
If it doesnt open the door at all, what happens? Does it site groaning forever until the motor overheats?
