Garage Door Opener And Cool Weather



Question:
My garage door opener will open the door in cool weather but refuses to shut it. When the weather warms during the day, it works fine. I have taken the cover off the opener and don't see any obvious problems. When I release the door from the opener chain drive, it closes by hand with no problem. Any suggestions?

Answer:
It could be that your garage frame moves just a little bit with the weather. Try turning the down sensitivity to the more or + mark just a little. Also, if you have a screw drive operator, try greasing the screw. Use only LOW TEMP grease. Lubriplate makes a low temp grease. I'm sure you can get it at any big box store. My service technician that has been with the company for 40+ years would also use a bar of paraffin wax and wax the jambs.
