I was in a home improvement mood today when I went to Lowes. I purchased, among other things, a new doorbell button. My previous doorbell button had actually fallen out, but you could still push the springs and the thing would ring.
Well, when I unscrewed the old button unit, I carefully took note that there were four wires, red, black, green, and yellow, however, only the black and red wires were hooked to the old unit. One on each side.
So, when I installed the new unit, of course it doesn't work.
Now I am wondering what I did wrong. Any ideas?
