Mother in law has a garage door that comes down with a jump then continues normally. Springs have been replaced but the right side of the door appears to be wobbly when I gently move it down with the door in manual operation. Does the video help in figuring out what's happening?

That first section of travel it is moving pretty quickly when it get to the directional change. Is the spring damper on the chain in good working order? Any chance you can change the travel limits slightly to have it stop on the open travel a bit shorter and still clear the car?

I am sure that Mike Hawkins will get you squared away. He is a wiz kid on these.

Thanks for the quick reply Windows. I had no idea that those springs could be adjusted. One side is definitely looser than the other. With my hand on the weak side I can easily move the door with light force. The other side has much more resistance. Perhaps this explains the jumping of the door when closing?

Also, the screw track that the door moves along is at not parallel to the floor - in fact it is canted upwards about 5 degrees or so. Does the track need to be parallel?

PS I used to live in Northern VA for many years - just outside of Middleburg near the Blue Ridge mountains. Miss that place.

Appears to me the side hardware on the door itself is catching. Dis-connect the door and try the opener alone for smoothness. The back-hang angle is standard safety feature on most doors, so it won't come down by itself if ever a problem. At least, that is the info they taught me before hanging a dozen doors and finding the travel time between jobs wasn't worth the money...lol.

Disconnect the door from the opener and open it. It should open easily. The side springs should be set so it is balanced and you don't need to lift a bunch of weight. Be careful trying to close it manually because it looks like it might try to slam down on you.
It looks to me like door is trying to slam shut and the opener is holding it back. That would mean one of the springs is broken or way out of adjustment.

I think the left spring is out of adjustment because I can move the left side easily while the right side has resistance. This must be why it's jumping on closing. How do I adjust this spring safely?

Thanks,

Nick

That's a west coast setup. Back in Ohio, we don't use that type of door hardware and springing. I've never played with that type of door. But I agree with what the other said. Disconnect the opener and move the door up and down slowly. You should be able to see what's causing the problem. That scissor hardware could have a bend or king in it that causes a bind for a second. Spring tension being uneven may cause the same problem. Have an extra set of hands and eyes around and keep an eye on the hardware on each side and watch for the glitch. Let us know what happens and what you find.

Nice part of town out in those parts, but I bet you don't miss the NOVA traffic.

Sounds like the folks gave you some good advice. Keep us posted on the door repairs and how it goes.
