    My garage door "Sears craftsman 139.53927" also doesn't open well when it gets 20 degrees and below.

    It opens about 4" and then I close it and then it opens about 2" and then I close it and it may open to 4" or may not the next time. I sneak under the door and try the inside button... - same thing. There is no ice built up unless it was just moisture from the car coming in.

    The colder it gets the worse it acts like this. I have tried spraying 1040 on the floor, the door, rollers and eventually it goes up.

    VERY FRUSTATING when it's cold outside.

    In telling my brother and a neighbor I found out that my brother's daughter/son-in-law have the same problem and so does my neighbor. How wide spread is this problem??

    No problem opening/closing it manually - I have had to do that a couple of times as then the door wouldn't close either after having the opening problems (above).

    Same problem....opens fine...but have to hold the wired remote to get it to close....even then it may take a couple of tries to get it all the way down. AND NO it's not binding, in fact does the same thing if I disconnect to door.

Interesting, Have you pulled the string and tried to open it manually? If so is it hard to open, If so something could be freezing int there, such as the grease (Although Highly Unlikely) If its easy to open, its something with the opener its self, I would call the manufacturer, have them look at it.

When the temperature gets near or below zero, my door comes part way down and then reverses. It works perfectly at higher temps. do you have a solution?

I re-categoried this question, hope it was garage door related. There is an adjustment on the motor unit that sets the reverse threshold if the door hits something. When it gets cold, lubricants can get thicker and the door senses the resistance and opens when trying to close. You can change lubricants or set the adjustment to a higher setting

During and after the cold snap here near Ft. Worth Texas the remotes do not open the garage door. I replaced the battery in one with no change. In warmer temps it works fine. The house button always...

If none of your remotes work and they all failed at the same time it is most likely the receiver that has quit. It is part of the logic board. The wall control is hard wired and doesn't use the receiver.

Our automatic garage door opener does not fucntion well in very cold temperatures (below 32 F). It will not close all of the way and will stop or will stop about half way down and return to the up position...

There is no adjustment for temperature. Make sure the tracks have not been greased. This sometimes causes a problem when it congeals from cold weather. There is no reason to ever lubricate the rails. You can try increasing the down force. It is a control on the rear of the motor unit near where all those white wires go. Increase it a 1/4 turn and try.

Remote will not open or close door when temperature is cold.

if this is an outside remote the best you could do is maybe put someting to insulate the remote if it is in your car don't leave it on the visor put it in the glove box or maybe the center console it is obvious that expansion/contraction physics are playing a part

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
