I have a Genie garage door opener. ONLY DURING COLD WEATHER does it act up. When I close the garage door it goes to the completely closed position and retracts. I have adjusted the limit switch and it does not help. When the weather warms above about 40 degrees, it seems to work fine.

So it seems the Main garage door unit on the ceiling is ok. The problem is with hand held unit. Usually the circuitry is ok. Try changing the battery. It has helped me. Also make sure the sensor on ceiling unit is not blocked ad is free of cobwebs.

UNPLUG RHE UNIT WAIT ABOUT 5 MIN. AND PLUG IT BACK IN.

THIS RESETS THE SEQUENCER.

SOMETIMES IT WILL SOLVE THE PROBLEM.

HOPE THIS HELPS

GET A COPY OF THE ADJUSTMENT INSTUCTIONS FROM THE GENIE WEB SITE - IT IS A SMALL AND SIMPLE ADJUSTMENT - BUT, IF YOU MESS IT UP THE DOOR WOULD BE UNSAFE.

Most photo electric eyes have sensitivity settings. A small dial or screw that can be adjusted.
If there is none, then another trick would be to recess back further from the actual opening, and put is on the wall as far as possible.
Finally, you could add a tube to act as a sunshield. They probably have one that can be special ordered for it.
And it even that does not work, consider taping a sheet of polarized film over it, like a single sunglass lense.

well the there are lots of possabilities but the most likly one is that there are shadows or pieces of debris that are on a laser detector or the chain that pulls the garage door is being heated while it is frozen which could change the signal on the closer. or you need a theremal cover on ur opperator system for the opening and closing on the door.... google always helps

I'd guess that the lights that sensse that something is in the way are dirty or not aligned properly and the cold makes it worse. Also make sure to get some WD40 on the door track and wheels and then the chain on the opener if it's a chain type.

We just had the same problem this morning (cold weather can mess these things up). Not sure what you mean by "not working". Ours would open part-way and then stop (or close part-way and then stop), but could open/close all the way if we held the button on the wall down the entire time it was lifting. After much research online, we ended up checking the sensors at the bottom of the garage door tracks to make sure that the green light was solid (not flashing). Ours flashed a bit, so we cleaned the "eye" and tightened it in place. Once the green was solid, we thought we were done, but still had the problem.

Then we began adjusting the screws on the unit itself that show pictures of the door opening and closing. We thought we were adjusting the torque in the unit (because we read online that cold weather can make it more difficult for the motor to work), but in reality we were adjusting the opening and closing "distance". Apparently cold weather can also do something to the tracks, which can require adjustments to be made. Something to do with ground swelling...

Anyway, we also discovered that when we had closed the door manually (red pull-cord) the night before for lack of a better solution, it never properly locked back into position, which was adding to the problem.

So, first, try cleaning the sensors. You need a solid green light for them to function properly. Second, if you have used the manual cord, make sure the arm that it attaches to is locked back into position. You can accomplish this by pulling the manual cord, manually closing the garage, and then pushing the button on the wall. The door arm should lock into place. Third, try using a screwdriver to adjust the open/close distance. Start with a 1/4 turn for each position, and play with it until you find the right setting.

If these suggestions don't address your problem, this link worked for us...http://forum.doityourself.com/doors-windows/368278-garage-door-wont-go-down-cold-weather.html

You need a general inspection of all related parts. Make sure none of the track mounting bolts have loosened leaving a misalignment of track segments. CAREFULLY with power off use fingers. turn EACH roller. Something as simple as a bad roller bearing can cause this, even a flat spot on a worn roller. Rollers can be bought at a home supply store. These are 2 most causes.

Sounds like a skinned wire on your front or rear limit switches is touching metal. Go over your low voltage wiring and test again.

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
