Garage door opens on it's own
So it appears when our electricity goes out our garage door opens when it comes back on. Yesterday it happened while we were at work. This is the third time. Anyone have any idea why this would happen and how we can stop it?
Thank you.

If the power goes out pull the cord. Once it comes back on you can revert back and then just run the garage until it catches again.

You may have a defective control module in the opener itself. But, you may have a problem with a remote or in the wall mount pushbutton or its wiring.

And if all else fails, it could be a ghost.  |

Garage opener working by itself
What happens to you is pretty common - power surges affect your motor control board in your opener unit and cause it to do odd things. First thing you should do is get a single outlet surge protector and plug the opener into it. To prevent surges from affecting your board, if you need a new one it will cost approx. $60-$70. 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.

Satan has possessed your garage door opener. Call a priest and schedule an exorcism. that is your only hope. Do it now before the possession spreads to the rest of your garage.

Perhaps someone in your neighborhood has the same opener code as you do! It's been known to happen! When a neighbor comes home (or leaves) and opens their garage, your's is picking up the signal!

When this happened to us, we learned that it was from trucks going by that used the same radio frequency as our remote. Not sure if that was really true or not though. Possession seems more likely
