Default Garage door jerks when opening
wrote:
Hi, I have a 10 year old garage door opener. When the garage door
opens, sometimes it jerks the door at the start, but the door opens
fine.
There are also few times when we close the door, the door will bounce
off the floor and reopens by itself.

Does it sound like a bad tension in the spring, or something else?

Thanks

Slack in the chain? Skipping sprockets?
