I have myQ and yesterday my garage door opened by itself. We were not home,luckily my alarm system notified us. My neighbor found the door open, I check when I got home the door would not function and a red light was blinking fast. I disconnected the unit and the garage door worked. Any suggestions? I don't want my door opening by itself.

Thanks for the response.  I've been in touch with a rep from Chamberlain from my Facebook post and the provided a solution today.

I also have the two of the 888LM garage door panels. One of the panel started similar random opening and closing on its own about a month ago. The most frightening thing is it started acting up while we were away from home on vacation for three weeks. Also, No alert was issued and no record in in the app. My neighbor confirmed the door was open but he thought someone is home.

Yesterday, It happen again while i was home and the panel is now completely dead. I cannot open/close or turn ON/OFF light. There is no light on the panel. However, it still randomly issues open/close commands to garage door opener without my intervention and there is no record of opening/closing in my MY Q account. it randomly open/close at least 10 - 15 times within 10 minutes of observation. I ended up disengaging the garage door and locked it manually. I have removed the 888LM panel from the wall to avoid any damage to the opener.

This is extremely serious safety & security issue. I cannot trust these control panels. The date code on my 888LM is 04/13. I have contacted the customer support team. I am writing this post to help other MyQ customers.

Just happened to mine. I contacted Chamberlain as there should be a failsafe to keep the door closed. I’m waiting for a reply, but doubt anything will happen. I replaced the wall switch and hub. As others stated, I’m glad I was home and the alarm wasn’t set. This failure should be a major concern for Chamberlain. A simple feedback circuit could prevent potential liability...

Phantom operation solved. At least mine.

I was having the same problem as all those listed above but noticed that on both of my openers the yellow light would flash a lot. Only one opener was having the phantom operation. Rounded up all my remotes, 2 openers, 4 remotes each programmed alike. As I found the last one the TX light was flashing at random intervals without any buttons being pushed, and only button 2. This was the cause of my issue. Troubleshooting like I do with other electronics problems I checked for a stuck button, no luck, all buttons click fine. Button 1 works like it should with the non-issue opener. I opened up the problem remote and checked the battery voltage. 2.7VDC. Thought it could be a low voltage issue. Replaced the battery with a known good one, 3.2VDC and the random TX problem still happened. Just to cover all the bases took the 2.7V battery and put it into a good remote and it operated fine. Both remotes have the same part number on the circuit board, 014D1175 RevC and show no indication of any kind of corrosion or solder bridging. My advice is to find and check ALL your remotes for this phantom TXing.

Seems to be a thermal/heat runaway issue. On the back of the remote board there is one small IC chip that runs everything. It seems that once it reaches a certain temp it starts randomly transmitting and every time it transmits it gets warmer and warmer. Was able to stop this by cooling the chip. However, this is unpractical in the real world. Think a redesign of this chip may be in order. Just my two cents from a guy with 30+ years of electronics knowledge and has seen this type of issue before on things costing millions more than this $5 remote.

We bought and installed our Chamberlain garage door opener a little over a month ago. The issue of the garage door opening started when we had some winter storms and power outages, so we put it down to that. But recently (past week) we have gone out in the morning to find the garage door open three times and no apparent reason for it to have opened. This is very worrying as we store items in the garage, rather than our shed for the reason of security and now the garage door opener is failing us. Having read all these messages that date back several years, of people with this issue, I find this very disturbing that nothing has been done to rectify the problem by chamberlain.

As it was a time consuming to fit the system in the first place, it would be a last resort to go and buy a new system from a different company. Therefore is there a fix we can do on the current door opener to stop this issue once and for all?

Thanks,

Helen

This only happened once within the circuit board of the switch/button failed. As we have an alarm sensor on the garage door, we added a slide bolt just in case. My new switch/button has not failed with a couple of power outages. You may need a new switch/button if it is failing often.

Thank you for your reply Steve. We have a slide bolt and did use this when expected storms were coming through as back-up over the winter. But obviously this is not something we want to do every night as we should be able to rely on the door staying shut. We will however look into getting a new switch/button, if it worked for you may be that is our problem as well!

Did you try using a surge protector?  When my door opened unexpectedly, the switch/button completely failed (had it for several years and it only unexpectedly opened that one time).  If your switch/button still worked after the unexpected opening, it could be something else (still under warranty?).

It is a new switch and it does still work. We did use the wiring already installed from the old system though. I think in some other feeds related to garage door opening unexpectedly, there was mention of surges in power, so we have been investigating surge protectors as an option as well. I think the thing that gets us is, this morning it was open, but nothing untoward happened last night or this morning that we noticed in the house to have made it open...
