    Color me stumped...Garage door issues.

    Hi! I haven't posted here in a while, but I have been looking in periodically. Got an issue with our garage door. This is a normal roll up door of wood construction. It is 18' wide. About 3 weeks ago, we started getting a gap at the left side. I have tried increasing the tension on the right side spring, didn't change. This morning I decreased the tension on the left side...still no change. I can stand on the door with it disconnected from the opener and it will go down, but won't stay there with weight off of it. In fact I have to bounce on the door to get that side to touch the floor. The gap is 2 1/2" at the far left side of the door, slightly out of the picture. Click image for larger version.

ID:	79033 I could easily add to the bottom of the door to get a seal, but that isn't fixing the problem. Any ideas? I can't see any cracks in the slab or the brick that would indicate a drop on that side of the house. Even so, I'd think the door and track would follow it down. I don't see anything binding in the track. The door moves evenly open to close, just not level with the floor. I'm stumped. Jim.

    First thing I would do is to check the height of the opening on each side to make sure they are equal. Then I would get as long of a straight edge as possible and check the floor for level. One of those self leveling lasers would be perfect for this.

    I would check to see if the guides for the rollers are still vertical and have not moved out of position over time.

    Alan, the opening height on the left side, the side with the gap, is 6' 8 5/16". The right side where the door touches the floor is 6' 8 11/16". This would make sense if the gap was on the right side. It is just more confusing since the gap is on the other side. The floor does drop 1/2" on that side of the garage. No cracks in the concrete that are perpendicular to the door opening that would suggest that that side dropped. Even added together, it doesn't add up to the 2 1/2" gap that has appeared. I do think that there has been a little gap all along on that side, but just enough to see a little daylight under it. I'm sure the thin gasket on the bottom of the door hid some of the gap.

    Bill, rollers and mounts are all still in perfect position on the door, both sides. Door rolls and opens smoothly with the lift and by hand. Nothing binding.

    I even checked to see if the door had warped. My longest straight edge is only 5', but I don't detect anything in the door top or bottom moving 2' at a time the length of the door. Does any of this raise any ideas? Thanks guys! Jim.

    When the door is down are the tracks parallel to the sides of the door and are they plumb? I would also pull a tape measure from the top of the door to the header on each side with the door all the way up just to make sure they are equal or pretty close to equal.

    Had asimilar problem due to one thingie's that hold the cable to the shaft for the spring shaft had slipped. I had to detension spring then adjust the position of the things and then re-tension the shaft. A very scary thing that I finally called out a guy to do since the spring could kill ya.

    Yes, parallel and plumb as well as I can tell. With the door in the up position, left measurement from the door's top to the header is 86", right side is 85".

    Both mounts are secure. Guess I need to check the right side tension on the springs. If it slipped on that side I guess it might allow the door to drop more there with less tension and create the change I see in the door to floor mating. Hmmmm.....Jim.

    Nope, right side has more tension than the left side by one stripe. Not sure if that is more than one turn or not. Jim.

    With the door down fully release all tension from the springs and see what happens.
