Thanks for all your comments.
I have power reaching my new bush button, which is seen by its light function. As seen in the picture, there seems to be some melting and discoloration to what I thought was the transformer. This is why I believe it is no longer working and the unit needs replacing.
Hi there.
So my door bell broke, and so I replaced the push button thinking that this was the issue. Turns out it wasn't.
I have purchased a new chime but the wiring doesn't quite match the old chime box. Can anyone help identify which wires are which? They are all white
Thanks
