Model#139.53675SRT2 works fine in warm weather but not in cold

If it is not a digital unit the remotes need alignment.

It is probably the lubrication in the rollers. You should lubricate them and make a small adjustment to the torque sensor. When it gets cold the lub gets stiff. The torque sensor will detect this and open the door, a safe position.

You have a logic board that is affected by temperature. The only cure is a replacement.

Some electronic components become sensitive to temperature and the only fix is to isolate the component and replacing it. In the case of door opener remotes it is cost effective to replace them.

There are ususally two adjustments on garage door openers...
One is for the pressure and the other is for the travel. Assuming that the travel adjustment is properly adjusted...

On a cold day things are a little tighter and it "wants" a little more downwards pressure to complete its cycle. Sorta like me in the morning -- I need a little coffee to get going on a cold morning.

Adjust the down pressure/force just enough to make the unit close properly. Do not over adjust the down pressure or you will find it won't stay closed. Sometimes the manufacturer doesn't make it too clear where this adjustment is, but you should be able to find it if you look around.

I have seen units that were installed for years all of a sudden need a little tweak of this adjustment.

Good luck

iv had a few people come in with that complaint I clean inside of door and spray seal with good 100% silicone spray and spray latches with penetrating oil

Pull the opener release rope and try yto open the door if it open hard the springs need adj. or door is binding in the track. if it opens easily then adj the lifting force setting on the opener

Check the electric eyes. If they don't see each other the door thinks there's something in the way. Blinking light is a safety alert to check the travel path.

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
