garage door opener with sagging chain, but only in warm weather

bsmy84

I have a Sears garage door opener that works fine, but its chain sags during the warm time of the year, and doesn't sag during the cold weather.

As I say, it works fine, but that sagging chain for about half the year bothers me.

Is it OK as is? ... or should I spend some big bucks to have some guy come out and turn a screw?

Metal expands in the heat. chains get longer. If its working don't fix it. You could make it be too tight in the winter.,
