Why my Garage door open/close by itself ?

[Nevika]

Hello,

I have chamberlain garage door opener. My garage door open/close automatically if my neighbor open/close his garage door.


his house is just 2 houses away from my house.

What causing this problem?

Thanks

Sounds like older openers with the same DIP code.

 

[The Cobbler]

yup. is the code re settable on your closer & remotes? time to switch it

Do you mean, I have to reset the pin code, i use in pin pad to open garage door ?

I had this issue:

Liftmaster Ghosting

I have a three-car garage with three Lift Master 3800PLD openers. I have an intermittent problem with mainly one door which will open by itself every so often. It’s been doing it for the past four years and is worse in the cold weather. I have had one of the other doors do it also, but not in...

I did, too. I have two doors, but only one door was randomly opening. The installer gave me the usual lines - must be somebody else in the neighborhood (there isn't anyone else with 1/4 mile), air traffic overhead, etc. I pulled the batteries on all the remotes (3) and still had the same random openings. I started turning off the breaker (openers are on a dedicated circuit), and eventually installed a switch in the line.

Eventually it dawned on me - maybe it was the wall controller. I mean, it should just be a simple switch, and it worked fine when I pushed it, so how could it be? Well, it was. A new wall controller and all is well again. What's disappointing is neither the installer nor any of the many Google search results mentioned the wall controller itself as being a possible solution.

Great, Thank you both for sharing your experience , I'll replace control panel. Do i need to change the Garage Door Keypad( outside) as well ?

That was not the conclusion that I was drawn to.
If you think the wall switch is the issue, simply disconnect it to confirm and see if that solves it before you buy another. Obviously that could cause it, but seems a little "uncommon" to me.



The garage keypad (typically unwired) is tied to the DIP switch configuration of your garage door opener (assuming it has DIP switches).

The 888LM wall controller is a known issue. It is due to a leaking capacitor on the control board. Chamberlain will replace it for free.

With that said, the OP stated his door opens with his neighbors. That's not a control board issue. Replacing the wall controller won't fix that problem.

Yes, I should have mentioned that. Pretty simple to disconnect. Probably not all that uncommon, though, if you can buy a replacement on Amazon and it has 1300+ reviews.

No, you have to change to wireless code your opener uses to communicate with your remotes. There's a button on the motor housing to erase the recognize remotes and re-pair them with the motor. This OUGHT to change the code they use / the code the motor recognizes. Thus it will ignore your neighbor's remotes.

Well, after 10 years, the other wall controller finally failed and went nuts.

This time I knew exactly what was going on and had it fixed 48 hours later, via another replacement from Amazon. Figured I'd bump this thread up for anyone else dealing with the same problem.

I had this symptom but it turned out to be the neighbor. I cleared my codes and no more issues.

That keypad is basically another remote. Should be good.

I dont have one of these 'randomly opens' openers but after reading all of the threads about them, I bought a manual door lock and installed it on my garage door. I want there to be a zero chance of my garage door randomly opening.

Hope you don't forget to slide the latch over before hitting the button.
