I noticed today that the chain on my garage door seems to droop a bit on one side when the door is closed. I feel like I would have noticed if it was always like this (new unit, about 1.5 years old).

Is this okay/normal? If not, is there a process to tighten it? Seems like it's been nosier lately!

where i guess chain may be able to be tightened?


Yes, that's normal because the drive is putting some tension on the other side of the chain and that leaves a bit of slack on this side.

  • Agree, the User's Manual will probably tell you to adjust the chain tension with the door open. It should tell you how much sag is optimum when the door is open.
