Craftsman 1/2 HP Screwdrive Garage Door Opener
I have a 6 year old Craftsman 1/2 HP Screwdrive Garage Door Opener that does not open when the temperature gets below about 40 degrees. It comes up about 6 inches and stops. I can "assist" it by pulling up on the door handle and it works fine in warm weather. Thus I believe it is not the door itself. The door is wooden, but is only a single car garage door, so I think the 1/2 hp opener should work. Any thoughts?
