Garage Door Opener in Cold Weather

Since the weather has gotten colder here in Ohio, our garage door will only open 1/2 to 2/3 of the way. We have to get out of the car with the remote and help push it all the way open. I checked the sensors and one is green and one is yellow. Can you tell me if that is normal? Also, there are 2 tension adjustments on the side of the garage door opener itself and 2 on the back. Do I need to adjust these? It is a 1/2 HP Craftsman GDO. Thanks.

Be careful adjusting the up and down pressures. The reverse settings should be at a point where little or no damage would be caused if a car was in the path of the door when the door is closing.
Screw drive units tend to be affected by cold more than chain drive.
Spray lithium grease is not normally cold temperature grease. It gets thicker as the temp drops causing the trolley to bind on the rail. Lubriplate makes a cold temp grease that is rated for use at 40 degrees below zero. Spreading this grease with a small brush on the lower and upper parts of the rail where the trolley rides. Spread the grease the entire length of the rail in a thin coating. My 16ft. door opened this morning in a temp of 4 below.

On down door reverses in cold weather


A garage door guy says that in colder weather the weather stripping can become stiffer, less pliable, causing more drag or friction on the door. You may need to increase the down pressure a bit. If it's set in the normal range, try increasing it a little bit at a time, but don't max it out.

My garage door will only open half way. It appears to be getting stuck when it is opening.


If you haven't gotten your issue fixed yet... I had the same problem (stopped opening half way when using the remote, went down fine, could lift/close manually fine as well) and this happened on our first cold weather day of the year which was very telling. Anyhow, there are two gauges/dials on your garage door opener unit itself (above, where the light is) which controls how much torque/strength your door uses to open or shut through resistance. I turned mine up some and it now works fine; what likely happened was that the metal tracks or the wood frame condensed in the cold and was providing just enough resistance to stop it when opening - as they have a security device built in to stop if they meet any resistance. Hopefully this helps!

Have a Chamberlain liftmaster professional 1/2 horsepower garage door opener that is only opening 6-12 inches and then stops. Just started in cold weather. If I keep retrying it, the door will eventually...


if you can open door Manually- find the FORCE adjustments-Not Travel. These might be "blue" in color. Increase the UP slightly. this adjustment in the cold weather is due to door hardware dry, lube rollers/hinges with wd-40 while door is down, lube every 30 days, keeps it moving quietly...

My garage door opener fails to send the door down when the weather is cold. It works when it is warm. Any suggestions?


I live in Florida, my spring broke when it got cold. The repairman said that the coil spring has to be lubricated frequently, especially when cold. Try spraying it down with silicone or wd 40 and see if it helps. You could also save the spring from breaking.

Cold weather. Opener lifts door ~8


If there is any grease in the tracks clean it all out. On the rear of your motor unit you will find the 'up force' control. Turn this about 1/4 turn and try. You also should take a good look at your door springs and make sure one isn't broken. Release the door from the opener and open it manually. Shouldn't be heavy and should stay when released about 1/2 way up.

Garage door opener will not close in cold weather


The are two knobs on the back of the opener. They are force settings. One is the upforce and the other is downforce. Turn both knobs to "5" and try. This should take care of the problem. They come from the factory at 1 or 2 and when it gets cold it takes a little more force to cloce the door.

Garage door opener


You can turn up the up and down force on the motor head to give the unit more power. During colder weather the unit needs more power. Afterward do a 2x4 safety reversal test. thanks, BB
