My garage door unit, an older Craftsman 1/2 HP spring driven 2 car unit (not sure of the exact age, but may be a '98), has taken to not working right now that it's gotten cold out. It will close almost all the way, then stop, the lights flash, and it goes back up. I can override this by pressing the button multiple times in order to stop the door, but obviously that's not a permanent solution. Also, this will exclusively happen during below freezing temperatures, if that is relevant information. Can anyone give me any advice/experience on how to fix this?
