Garage door openers do not have reset buttons so the only way to reset them is to unplug and let set for at least 30 minutes - plug unit back in and walk to the wall button(not a remote device) - activate unit. If it acts just fine then all it needed was a reset.

I've been dealing with the same problem and believe that resetting the remotes at the panel control board is the answer to the "Phantom" opening problem. (See your opener manual for remote reset instructions) I did it 3 days ago and haven't had a "Phantom" opening since. I will continue to reset in the future if it happens again.
I do have one issue with using a surge suppressor: I used one that I had to protect some computer equipment and after doing so , I found that my outside remotes would not open the door. It would not open unless within 3 feet of the opener.
Afterwards I learned that LED lights throw out radio interference waves which can cause problems with other electronic devices. I then noticed that the surge suppressor had two tiny LED lights. (One red, One green). I removed the suppressor and plugged opener into AC receptacle and the problem was eliminated.
Also note that some people use LED light bulbs in their opener. (Not a good idea!)
I took it one step further:
I opened the suppressor and found the wire leads which were connected to the
tiny LED lights and then snipped and removed them. After closing the suppressor, I re plugged the opener and suppressor and it was double proof that LEDs most definitely interfere with remotes. It eliminated the problem
I am not saying that "ALL" suppressors with LED lights will cause this problem, as others may somehow be shielded from emitting the interference. I don't know how you will be able to determine this when purchasing a suppressor, but it will save bucks by asking the sales person if he can guarantee that it is shielded.
Good Luck!
