Agreed, which is why I replaced the switch, then disconnected it for a
period of time. Unfortunately, the symptoms continued during/after both of
these tests. Hmmmm...

@g49g2000cwa.googlegroups.com:

Most switches operate with a metal spring beam that makes contact when
you press the button. If the metal ribbon fatigues over time it will
rest against the contact intermittenly and may make the garage door
open and close. I had this exact problem with my remote. I would
suspect the hard wired wall switch.
