Hello .. I cannot seem to find info on that number .. is this a wireless switch system .. in my opinion if it is wire\less and neither switch is working , then it would be the main that is faulty ...
I would replace both units to make sure that the technology is compatable ..
first I would remove the main and splice the two black wires that are on the switch ,, to be certain that the wiring to the light is OK ..
If these are wired switches then let me know and we can troubleshoot them together
It is a wired switch system. I have jumpered the two black wires and that is how I verified the wiring. The light goes on when when the black wires are connected. I do not believe these systems are manufactured any more. so the only think I can think of is to go on line and purchase one of each unit and see which is the one
And see which one needed to be replaced.
I have finally found two units like the pair that does not work and the second one I tried made the lights work. So using that method my problem is solved.
OK .. good work .. Thanks for using Just Answer .. Rich
I will try again in the future. I guess it was something that could not be answered.
