Strange Sears 1/2HP Remote Behavior
The hard-wired wall switch works fine: up, down, stop part way, whatever I want, as many times in rapid succession as I want. The motor and mechanism sound normal. However, both the wireless handheld remote and the wireless outside keypad are doing something strange.
I can operate the opener with either the remote or the keypad, but then it (either device) becomes ineffective. However, if I wait about five minutes (I've actually timed it) then the remote works again... but only once until I wait another five minutes.
I've checked this many times over the past 24 hours, and it is absolutely repeatable. What the heck is going on here, and what's the cure?
The system is about circa 1997
