Most every morning when I leave for work, the garage door only opens about half way after I hit the remote button on the control panel. I have to continually push the remote button over and over again before the door finally opens all the way.
The rest of the day it works just fine, but in the morning when it is cold (50 to 60 degrees F) it only goes down about half way and stops. I then fully close the door and try open it again only to have it stop about half way up.
The brand is Liftmaster and it is about three years old.
I would appreciate any ideas what the problem might be.
