Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

2 Answers

Garage overhead door will not go up in cold weather.

We have a Chamberlain overhead garage door opener. It works fine in the warm weather, but now with the cold weather, it will not open on it's
own. Have to help it go up. What can be the problem, or is there any adjustments that we can make, so that it will work?
Thanks for any help you can give.

The green eye receives the the signal from the Amber side. When is not on the sensors won't work. As far as the cold chamberlain did have a few issues with sensors not working or intermediate issues in cold weather. Their solution was to replace the sensors. But before you do that check everywhere the wires are stapled. Make sure that they are not pinching the wires.

Some electronic components become sensitive to thermal changes and there is no fix other than replacement.

Garage door not opening properly.


Check the springs on your garage door. If one is broken, the opener will not have enough power to raise up and it will stop like that.Or the up and down limit settings have gone off or bad.

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 will not open!


Sounds like the contactor is bad. They don't make the part for that operator any more though you could make a differant contactor work. The easiest thing to do is install a new operator. The door and the operator are seperate things. You can replace your operator now and your door later.

Leave car outside. Seriously, try a little more force to force adjustments.

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
