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.

Tempted to chg myQ email to a different email as a test, next wil be husband checking on the circuits as other person indicated.
They finally replaced it a week ago but they did not replace the panel on the wall. My garage door opened again several times. I've told them this is unsafe and that if something happens to me they're gonna be held accountable for my safety and security. The company is making it like I did something to programming and their guy programmed my remotes and my vehicle.
Then tonight the night before Thanksgiving, My doors open twice during the day. Yesterday I came home and my garage had been open all day so I set up the Wi-Fi to to be notified.
Tonight I was 20 miles away and had been gone for the house for 2 hours when I get an alert that my garage door opened. Someone needs to investigate and maybe news agency needs to get wind of it if they're not concerned about customer safety. I called Banko and they told me maybe when I set up my wifi I programmed to someone else. WTF that doesn't even make sense. Why would programming to someone else open MY home. And I did it because it opened repeatedly and I wanted a warning. Every excuse except the truth.
Apparently I'm just a dumb female who doesn't know how to work my garage door. Oh and apparently I can be a half hour away from home and hit a sensor. Very upset.
We're removed wall control, too rule out it being the issue. Garage continued to open randomly. To be clear our door was only opening, not closing on its own.
I called Chamberlain and they said it was the control board. They sent it out and arrived a couple days later, hubby installed it and wall mount, reprogrammed all remotes and it has been fine ever since. Our garage opener is about 4 years old. My suggestion is to make sure you use the app and set alerts so you are notified at least if you are away so you can close it. The day i called the company i esrd running errands all around town from 930 until 330. My garage opened 7 times during this time and i closed it with the app each time. It opened again as I was on hold for a rep to track my call. Good luck everyone, it was certainly scaring and frustrating and im surprised no one had been hurt or a class action suit going yet.
Did a little research to find that this is far too common a problem. WTF, LIFTMASTER/CHAMBERLAIN?! You got a SERIOUS issue here that requires real action, not just chalking it up to “Phantom openings due to cross signals with neighbors”. The odds that we are all experiencing cross signaling from neighbors as often as is being reported on this forum alone with units that roll codes is astronomical.
You guys need to take ownership of this defect and you need to take ownership of it months, no, YEARS ago.
I’ll be informing my insurance company of this issue to ensure LiftMaster/Chamberlain are held liable should I lose any belongings in the future

This is seriously some BS and it’s funny how Chamberlain says “few” reported issues. I don’t think they’re addressing this properly, if not for liability than simply customer satisfaction. This is obviously a major defect and there’s enough of us on here seems it would be a great class action if anyone knows a good lawyer. Get us all on this post!
