He said that he changed the wire & the switch in his original post so
it sounds like a stuck button on a transmitter. When a trans button is
stuck it will sometimes disable the wall button & cause phatom
operation.

Does the problem only happen when a certain vehicle w/ a transmitter is
at the house. If so that would be the one to check. Disconnect the
battery & if the battery is still good re-connect the battery & if the
button is stuck the opener will operate without pushing the button. The
metal tab under the switches tend to flatten out & if it isn't cracked
bend the tab up away from the contact point. If its cracked, replace
the transmitter.
