What can you do for garage door openers in really cold temperatures?

Answer 1

Garage door openers typically rely on a grease in the channel to keep them running free. When the temp. drops below freezing this grease will solidify and freeze up causing the operator to chatter. Pull your vehicle out of the garage, put some newspaper down under the drive mechanism and get a can of spray lube like WD40. Disconnect the operator from the door so it can spin freely and open it up about six inches so it's not on the limit to tell it to stop. Spray the WD40 directly into the drive mechanism and then stand back and run the unit in both directions for a few seconds three or four times. After you have done this wipe the old grease out with a rag and repeat. Now that the drive mechanism is clean take some white lithium grease (available at any hardware store) and apply a fine bead all the way along the drive mechanism. Now run the unit for a few seconds each direction and then reconnect to the door. The operator will sound like new and work in the cold. This should be repeated before every winter. 22 years I worked for a door company in the cold Midwest, it works everytime.

Answer 2

Make sure that the working parts are free of heavy grease - WD40 is best
