If the jack doesn’t work by itself or with the “all” buttons I’d say the issue is in the controller board and not with the keypad. The coiled phone cord sends codes down to the controller so very unlikely to just fail one jack. Also if the other 3 run when pressing the all up/down buttons that means the controller keypad is working and the issue is local to the controller board for that one jack output.
If it were mine, I’d open the control box and see if it’s something cheap like the $8 relay on my fridge’s control board.
Thanks wnjj. all function except left rear leg down with the all button. anyone any help how to test the board relays? i can hear relays click for other functions. Going to try to test some later today. happi Jac no longer makes parts for this vintage. $500 to convert to wireless which is only option they have. i tried and tried to get tech support on how to test the board to see if a single component could be replaced. they do not provide that info.
Sorry, somehow I missed this reply all this time ago. I'm not surprised that nobody would provide support for the board itself as some much these days is "not user serviceable."
If you are still interested in a non-workaround fix, a picture of the inside of the box would help. I suspect there are a bank of relays on that board and the one for that one jack, one direction is bad. You would just need to find someone who can solder to replace it.
