Over the last week or so the garage door just randomly opens. This has happened about 3 or 4 times at this point, that I know of. Today I pull in the drive to an open garage door. Good times!! I love the fact that my 69 Mustang, tools, you name it where just wipe open for all to see. Anyone have any experience with garage door openers? Is this any easy fix, can you adjust the frequencies from the openers? Any thoughts? Thanks in advance!

How old is your opener? You need to read the operators manual. If it is old enough to have fixed codes, the first thing you should try is changing the code.
If it is newer, it gets more complicated to change anything with rolling codes.

X2 If its an older model it could be anything, a plane flying over (are you in an airport pathway?), any Ham Radio's in the neighborhood ?, a cop or cb radio, anything with a radio frequency can activate it.

With an opener that new, it isn't a signal opening it. Probably needs adjusting or a switch is bad.
Make/model, learn code button color? Give us something to work with here...
Its a Chamberlain Liftmaster Professional 1/2 HP part # 41A5483-1C. The learn button is red. Hope this helps.

Modern openers use a code hopping transmitter and receiver that are synched together and are practically impossible to exploit. That said, strong RF fields and transients in the power lines have been known to unintentionally open doors. We installed a Genie code hopper on our old opener after the electric knife kept opening our Garage Door, problem solved. Need more information on brand and model of transmitter and receiver, perhaps research from the manufacturer website or email manufacturer for assistance. RF chokes on the 110V and signal lines might solve the issue but that would be a pure guess.

Thank You! I'll dig into this in the am to see what kind of damage I can do.

Check each staple on the signal wire where they are stapled to the wall and ceiling. If there is an intermittent short on the signal wire the door will open. Might get by with just tapping each staple with a screwdriver handle.
Generally red buttons don't act up... More range loss than anything else imho (Except these are the ones that can go loose remotes fuctionality for days when homeland/military run excercises)
Yeah, unplug wires for the wall station at the opener - see if it resolves. if it does - then rerun the pair to the wall station, and reconnect.

I found my wall button seemed to stick down, keeping one of the two switches engaged and randomly opening AND closing. Once I began the habit of pulling the switch button out every time I used it, no more random openings.
