I have three 8500 Elite openers mounted on three garage doors side by side, wired to 888LM panels located at each. All have worked great until I recently reprogrammed each to operate from the corresponding button on the three button 893MAX remotes that came with the operners. After reprogramming was complete, all the doors worked as expected until about an hour later when I noticed the yellow LED light on one panel was not on. I tried shutting off the power to the affected door/panel for around 15 mins, but when power was returned it still did not light or operate. I tried swapping two of the 888LM panels around but the issue followed the panel. I then disconnected the panel overnight to let everything discharge, reinstalled the panel, returned power to it, but the problem is still present.
I am not sure what else I can try, I do wonder if there is a way to "reset" the 888LM panels when they act up like this...
Any suggestions would be greatly appreciated. Thanks
