I'm having the exact same problem, with the same garage door opener. It will open as usual with a touch of the button, but to get the door to close, you have to hold the button down until the door is all the way down. If you try to close the door with a touch of the button (as you normally would) the door moves about an inch, stops, retracts, then begins flashing the lights on the opener.

Control board has thermal issue. Bad solder joint that contracts when cold could be the culprit. Take out board and carefully resolder every ****** connection on board.

Batteries are affected by cold temperature.
Just like a car battery won't have enough power to turn engine when battery gets weak and it's cold outside.
I'm guess your remote is stored outside in cold garage.
See if remote battery can be replaced with fresh one.

The bottom door is not closing right. I can slide


Normal 0 MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman";} The lower hinge on each door may have a door closing cam. It raises the door up ¼ inch when opening and this assist in closing the door. If it’s wore out and doesn’t work the door may not seal and the gasket can be damaged. Watch the operation of the door to see if it rises up when opened.

Leave the door shut and let the magnetic gasket hold the door in place. Put something between the bottom of the door and the floor to hold it in case it slips.
Remove the bracket holding the pin and hinge assembly taking note of order of removal of parts. Slide new cams on. You probably need two.
COLD GARAGE
Not all refrigerators are insulated the same and not all condensers are in the same place. Your cold control is monitoring the temperature of the refrigerator section and is designed to turn off the compressor to keep things from freezing in that section. If it stays cold long enough outside in your garage the cold control thinks its cold enough and won't turn the compressor on. A makeshift closet to hold a little heat the unit generates will probably help.

Try increasing the 'down force'. You will find the control on the rear of the motor unit near where all those white wires go. Increase it about 1/4 turn and try.

Only when it's very cold outside my garage door


It sounds like the cold is affecting the door sensors. They each have a small light that should be lit and not flickering and they must be pointed at one another for the lights to work. It could be the cold is warping whatever they are attached to or it could be a case that they just fail when it is cold. Some sleuthing may be called for.

Garage door won't close by remote in cold weather


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

Garage door wont close in cold weather


find force adjustment on logic board and turn clockwise A LITTLE to increase down force. Try to stop door. You do not want TOO MUCH FORCE as that is a SAFETY HAZARD.

Automatic Garage door reverses and automatically opens after closing


I can't believe it! My opener works fine a 10 degrees and above but below 10 degrees it would go down a little ways stop and go back with the light flashing. I checked the electric eye and found it would go out of alignment when the temp drop. Who knew!
I made the adjustment and it now works fine.
