My bedroom sits directly above my garage; so, with a chain driven LiftMaster opener, I know every time the garage door is opened because my bedroom floor shakes.
I was awakened 2 times tonight by the sound of my garage door opening. In 10 years, I've never had a problem with the opener until the night I installed this product.
Here's the weird part. After opening itself the 2nd time tonight, I unplugged it from the power outlet. A few minutes later, the door opened again! I then got the ladder back out and took it and the door sensor down and deleted the device from the app. Knock on wood...it hasn't happened again since.
Anyone else have similar issues? Why would it open again even after cutting the power to the device? This happened late at night, when none of my neighbors would have been using their openers, so I doubt it's any interference from them.
Later that day, one of the garage doors opened on its own, closed, and opened again.
We hadn't lost power, we didn't have anyone doing work on the garage doors or anything electrical, we weren't doing a seance, and the moon was not full. Are there any lame excuses that I failed to address?
None of the excuses matter anyway. I told my wife that there's no coming back from this. I don't care what went wrong to make this happen; it is absolutely unacceptable and I'll never use it again. I have no idea how anyone could ever trust these products after such an event. I'm not troubleshooting; I'm not contacting support, I'm not replacing anything. (Though I have reinstalled the old school wall controls.)
I mean, think about it: Without our intervention, two years after installation, a garage door opened unexpectedly, closed (and could have hurt someone or something), then opened again.
You can bet the farm my next openers won't be Chamberlain.
To all consumers with phantom opening problems with their liftmaster garage door openers. I personally own 3 from the 8500 series and have been dealing with this phantom opening problem for years. Phantom opening is when your garage door opens and closes all by itself. Like many of you, I have come home and or woken up in the morning to find out that my garage door opened all by itself, VERY scary and unsafe for many obvious reasons. I have spent many HOURS of grief on the phone with their technical people and have tried many different attempts at fixing this including but not limited to changing remotes, rewiring, reprogramming, changing circuit boards etc. This morning, I was able to ‘catch’ the door going up and down dozens of times by itself which I captured on video.
The myQ wall control is the culprit people. I am an electronic technician by trade and decided to do a little troubleshooting myself. The copy and paste solutions the company keeps posting is a joke and they obviously have no respect for people’s time and safety. Call them and have them send you a new myQ programmable wall switch. I disconnected mine and the door stopped going up and down by itself. After dis-assembling I quickly noticed that capacitor C1 and C18 are leaking causing a short in the circuitry which is making the door go up and down. This is a common problem on electronic circuit boards nowadays and is most likely due to the cheap inferior capacitors being used. I would like to admonish the company for not figuring this out on their own and caring so little about the safety of their customers.
They won't accept any liability, not even a replacement for the controller. Pathetic service.
They said that they new controller has the issue corrected and that it shouldn't fail in the open position. Considering the simplicity of controller, I am finding it hard to believe if they are using shoddy capacitors that it wouldn't short in the open position again.
Can anyone confirm the new controllers don't have the same issue?
Ron, excellent work in finding the leaking capacitors! I encountered a ton of similar issues with other electronics manufactured in the 2000-2008 timeframe. Supposedly the bulk of "capacitor plague" has been resolved, but many companies (Chamberlain likely included) are still using up old stock in making new products.
That being said, my phantom opening issue is not caused by a wall-mounted control (because I don't have one hooked up to the device in question). I have a slide gate opener that is controlled only by two wireless remotes, and a MyQ internet gateway. Our problems with the gate opening by itself started shortly after I connected the internet gateway. It's even more frustrating because everything seems to work fine for months on end, and then with no warning the gate will start off on a series of random open/close cycles (many times being interrupted with the gate only making it halfway open or closed during the phantom cycles).
I believe there may be multiple issues here. There are obviously defects with the construction and integrity of wall-mounted controls, as you've highlighted. There also appears to be defects with the embedded control boards within the openers themselves, or a messaging issue related to the back-end infrastructure that runs the internet-connected portion of the MyQ system (Chamberlain's servers and related software).
I have submitted a complaint to the Consumer Product Safety Commission on this, but have not received any follow-up. This is disappointing to say the least, as it appears that we now have a company that doesn't care about this issue, and a regulatory agency presented with clear evidence of a safety issue that is apparently doing nothing. It's bad enough thinking of people's property that's being put at risk because of this, but even worse that a child may end up getting severely injured or killed as a result. I would encourage everyone to contact any regulatory agencies they can think of and continue to provide reports. Also, it's probably a good idea to start maintaining a backup copy of the complete text of this thread. This is still a site controlled by Chamberlain, and it would be all too convenient for all of these reports to go "poof" if litigation ramps up.
Same deal just happened to me last night. I have 4 openers. I checked my app this AM and noticed one of my doors had been open for 12 hours. I checked my cameras and confirmed I did close it. What I find odd in my case is that it shows the door opened by itself but did not auto close as it always does. It should close on it's own after 15 minutes as that is how i have it configured. The next log shows it being closed at 8:58 which is when I manually closed it w/ the app. So not only did mine open on it's own an hour after I left the property, it appears it also did not auto close as it should after 15 minutes. I don't know if it's the GDO or the door opener button panel causing this. I set my app up to alert me via push message when it opens just so I can monitor it for now, god only knows how many other times this has occurred.
I contacted MyQ and they are sending me 4 new 888LMs to replace mine in the hopes it fixes it. I'm going to check for leaky caps in door2.
Do you guys have yours set to auto close as well? If so, did it auto close or just close on it's own at some random interval?
We wanted to follow-up on this thread. A garage door opening by itself should not be happening, if you are having that happen please email us at firstname.lastname@example.org with the subject line "myQ Community. Random Door Openings- "Your name on the Community" and we will have agent look into this right away.
I emailed Chamberlain the other day and got the usual response on what to do to have it relearn etc.. I did that yesterday and it seemed good but just now it did the open and close on its own again.
As a female living alone I find this scary. Luckily I'm in a relatively quiet neighborhood. But I'm not tech savvy enough to take anything apart other than the remotes. It's too cold in the garage right now to mess with the relearning task again.
Is there any way to just take it offline and use the remotes only without the wifi and be sure that it won't open and close on its own again? I'm fine with that. Lived that way for 40 years lol.
