Neighbor called - Said my shop was open

[kc5dlo]

Got the call Sunday evening that the main door on my shop building was open as my neighbor was returning from a run to the store. He knew I was out of town and gave me a call. He looked around and nothing seemed to be missing or out of place so he hit the button on the door opener and it closed and locked. Then last evening on his way home the door was open again. He stopped his truck in the street and when he did, the door went down! Thinking someone was in the shop, he immediately called the Sheriff an they were there in a few minutes. I gave the code to my neighbor and they opened the door and looked around but no one was inside. At that point I finally was able to calm down and rationalize that something was going on with the door opener.
After the deputies left, he went to move his truck from the middle of the street and when he was heading back it closed again. I had him climb up and pull the cord on the opener after it was down and locked so it would stop till I can get back there and troubleshoot what the problem is.
The opener is a Liftmaster jackshaft type. I have a wireless keypad outside the door and a wired controller in the shop. All remotes are accounted for and not on the property. I am guessing that something flakey on the control board in the lift unit, but not sure how to troubleshoot the problem. Any ideas?

Thankful for a great neighbor.
Steve

Sounds like it may have something to do with your neighbors truck if it seems to happen as he drives by. We had a door opening and closing by itself one day and took us the better part of an hour to figure out that one of the vehicle remotes had a button that was stuck in. This was in a fire house with multiple remotes and we only figured it out when the Chiefs car left and the door stopped, he drove by and it opened by itself again.

Another possibility is moisture getting into one of the controls. That will make them do weird things.

...Any ideas?

I don't know if changing the code to something else would help... any neighbors that might have the same opener?

I know you said all remotes were accounted for. I was out of town and the wife was home alone and our remote control fan would slow down and go into reverse, then repeat in the other direction. She thought someone was outside screwing with her... the other remote was under a book.

Our Might Mule driveway alarm gives off false alarms, always just as I've gone to sleep ullinghair:

Years ago our neighbor had the same problem...turned out is was a CB radio in a vehicle that passed regularly. Wonder if the same thing is happening with OnStar or GPS? You might want to get your book out and reset your openers to a different code.

Good neighbor.

I am also betting something else is telling it to open/close and that there is nothing actually wrong with the opener.

I have the same opener too. Only complaint so far was not being able to set it up without the stupid photoeyes. It seems you cannot just jumper them out anymore:mur:

any neighbors close enough were there TV remote could be talking to your garage door. It has been years ago but this happened on the neighbors garage door where if they used the TV remote it would open and close their garage door.

Did you change the factory code for the remote controls when you installed to door to something different?

Ghosts, I tell ye, it's ghosts...garage ghosts, they're called :cloud:

Right, I also think it has to do with neighbor's truck...
