Title: Electric garage door randomly opens
Post by: Baylor3217 on July 24, 2013, 12:34:11 AM
Paid to "fix" it and its back.

Come home and sometimes it's open.

Thoughts?

Not safe

Get the company or individual who "fixed" it to come back to evaluate it.

I've heard of four main ways this happen. First, someone in your neighborhood has the same GDO set with the same code. (Unusual, but possible.) Second, something is actually blocking the door from fully closing, or something is damaged or degraded that the unit seems to think something is blocking the door from fully closing, and therefore as you're driving away the door opens back up. (That's easy to check... wait for the door to go all the way down, and sits there for a second or two.)

Third, someone is deliberately going through neighborhoods with a GDO, playing with various codes, looking for garages to open to see if there is anything worth stealing. And finally, the motherboard or CPU of the GDO is damaged, causing the inconsistent behavior. That would require a complete replacement.

Five: there is a mischievous child either upstairs in the house or hiding in the bushes, pushing the button on an opener and trying not to giggle too loudly as you try to figure out the problem.

along the lines of what bUU already said: I knew a guy that built a box that cycled through codes "just to mess with people".  Some folks do the same for more criminal purposes.
