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.

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!

I have two Sears 1/2 hp garage door openers. Cold weather problem


Very strange they both have the same exact problem. I would suspect something with the brackets is changing. When you are having this problem and the light on the receiver unit is not lit, tweak them a bit and see if it comes on. The odds of the logic board in both openers having the same thermal problem is just too high.

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
