Gargare Door Opener Sticking

I'm having a problem with my garage door opener sticking/stopping when it gets up about 1-2 feet of the ground. The strange thing is that it only does it when its cold out side (below 30 degrees or so). Any idea's on what I need to do to correct this problem?

It's a Sears Craftsman

Me Too

My low end model of a craftsman opener is doing the same thing this a.m. according to the wife (I'm at work). She said she was able to open the garage door with the opener this morning. When she returned an hour later, the door would not open.

The opener will go up about 4 inches, go back down, and then go up again 4 inches and remain there.

It's cold outside here too...about 30 degrees at the time.

There are no obstructions according the wife and the electronic eye has been verified as functioning.

Please, any suggestions are welcome.

Dave

Have you tried to adjust the up or down force. There are two adjustment screws label up and down force. I had the same problem when my door was closing. I turned the down force screw a quarter a turn and now it works fine in the coldest weather.
Before you do any adjusting you may want to disconnect the door from the opener to be sure the door is working properly.

id check the nylon drive gear that drives the top sprocket. just use a flashlight and look inside the case for white, powdery shavings.

And what if we see white powder shavings? Is it bye bye to the garage door opener?

I believe you problem is due to the cold weather. When it gets cold many openers will not operate correctly. The same symptoms your has. Even with full tension, many will not close.
Now if you have some plastic filings, then you probably have stripped the gear. Good Luck

I don't believe the problem is the gears. If the gears go out the door will operate erratically or not at all no matter what the temperature.
If you do open the GDO up and find nylon dust you can get a gear kit from Sears. The kit has instructions but it can be a challenging job.

I 'm the wife of ledfoot. We have a Sears 1/2 horse model #139186006 . The garage door had been sticking because of the cold. Some binding in the track. Lots of wd and things seemed to be fine. Now motor runs but no movement. When released door moves freely. Gossip about a shear pin. How to know for sure. Bought old house and seems to be an old model. No schematics. Also curios about where the release is there seems to be a seperate piece should these be together ? The wife needs help! Thanks!

Yep, I have the same model you do...in fact my first opener which was also a 1/2 HP Sears Craftsman did exactly the same thing yours is doing now. I ended up replacing it with a Genie Screw Drive. I was able to fix my other craftsman problem with the help from one of the replies above by turning the force screw a quarter turn.

Thanks for the advice!

Ledfoot:

Was the motor running and nothing moved before you pulled the release or after.
If the motor was running and nothing moved before you pull the release then you may have bad gears. The only way to tell for sure is to remove the cover and check. If there is some nylon dust inside the cover the gears are bad and will need to be replaced.
If the motor is running and nothing moves after you pulled the release then the trolley may still be separated. The trolley is the little gezmo that is hooked to the chain on the rail. There is also another part of the trolley hooked to the J bracket that hooks to the door. When you pulled the release these two pieces separated. If the two pieces of the trolley are not engaged the door will not move.
I looked up the model number you gave and couldn't find it on the Sears web site. You opener may be to old to be on the site or you gave us the wrong number.

Thanks for your advice! The trolley keeps seperating on me. Nothing to do with the release it's working properly. When I put the two back together they click into place, but when I pull the release the two come undone. Lift cover off of the motor and nothing but the chain and one black metal gear. Going to give it another try tomorrow. Maybe time to get a new one. Any advice on what to look for in a new one? Thanks again! ledfoots wife.

I had the same issue, the cold weather. The quarter turn worked for me as well. Thanks for the help.
