I’ve been using the X-10 system for sometime and it’s always worked perfectly. I have 2 wall switches and a wall plug module setup in my den.

Recently I had to unplug a few things while I had the carpets cleaned. When I plugged everything back in I noticed that the IR unit wasn’t working. I tried plugging it into different plugs but nada. The LED doesn’t come on when I push the buttons or use the remote.

Is it possible that it just died without a whimper? Are there any components inside the unit that I could get replaced or is the life span of these receivers only a couple of years?

I believe there tagged as an IR-543??

Thanks
