ot/garage doors

When I got up this morning both of my garage doors were open. What will make them go up without the switch being used? Thanks in advance Amo

If you are at all as careless as I am, one door was open, and you punched the button to close it, and went into the house, never realizing you hit the wrong button and the noise you heard was the second door OPENING!

It happens. We have one that will do that once or twice a year. And it is out in the country. Years ago an aircraft flying over would do it once in awhile. I have also started one down and walked off and something broke the red light and it went back up. I have also heard that BAD PEOPLE drive around with remotes seeing if they can open one.

Could be a few reasons. Someone else is on the same radio frequency if you have remote control capabilities but the two doors are probably on different frequencies and there are a zillion combinations so that's probably not the answer. Another thing could be something tripping the photo eyes if you have them, making the doors go back up but on both doors? A cobweb can trigger them. Third reason could be the doors coming down on something and going back up, but again, both doors? Seems most likely someone opened them up.

Back in the very early sixties my granddad who was a contractor and lived in Blair Ne. had an electric door opener with remotes, something new in those days. The door kept going up and down on it's own an somehow he found out the radio signals from the planes coming and going out of the Omaha airport were triggering the door.

We had a garage with three openers. During thunder storms it was not unusual for one or more of them to come open. Did it from the time they were new.

Our car has built in door opener switches that are located overhead but you can't see them in the dark and I can't feel one from another because they are flush with each other. But if my fingers were sensitive, I could tell them apart because they have brail dots on them for blind people. Does that make sense?

Wind. Wind rattles the doors and that moves the safety eye and the doors go up. Now before someone says it can t happen I can show you the foot prints where the door is being opened from a small mule kick every day. (not my door)

If you have an older opener (twenty years old or more) without "rolling code" remotes, it's possible for another remote to open your door. But both doors? I doubt it. I suppose an earthquake could trip the down pressure sensor.

Got any teenagers in the house? You know by now that wherever a teenager goes, unexplained phenomena follow.

Do the rest of cars controls have brail on them LOL.

my saftey eyes are mounted on the door jam, not
the track or the door. Don't see how this could
happen. Why would you mount the eyes on something
that vibrates?

I have punched the wrong button, then corrected myself twice and left both open. I really doubt anything other than someone pushing buttons could do it.

While we're at it does anyone know why my garage door goes up about a foot and then stops in colder weather?(below 20f) Its spiral gear drive and I have greased it and the door moves easily by hand. I'm thinking may be the start/stop relays cause they are mounted on the rail with the gear and it moves a little. It's not the safety beam.

Try assisting it, that will tell if it is a torque issue.

Chris Jones · Mar 1, 2015

Are you 100% positive it was fully closed and had stopped moving when you last closed it? Just me but when I see it's headed down I go about my business confident it will close. I've had times when...
I know it will shut with an air hose under it, but turns out not if the air hose is in the very center of the door--it reversed.
Once it reversed when a chunk of ice happened to be under it.

I'm sure too that if the tracks are tight and it starts to bind even due anything including wet and frozen wheels it might encounter resistance and reverse.

Chris Jones · Mar 1, 2015

The cold might be causing the rollers to not move freely or door sections to freeze to each other thus not opening up when the door starts turning at the top.

When the opener encounters more than a certain resistance while opening it stops. I'd open the door manually when cold and hot and try to determine if it's harder to open cold. I'd resist the urge to just increasing the force it will use until you learn what's going on.

Also be aware it could be the opener itself--the motor, chain, gears might not operate as freely cold for some reason this requiring more effort.

Leroy · Mar 1, 2015

Auctioneer friend was having problems with finding his door open every once in a while. One day he happened to be setting in front of his pictur window looking out at the road, saw a car go past and at that instance the door started up, happened several times and determined when the radio in car was changing stations.
