I have a doorbell that is not working. I know it is the transformer - but I can't seem to locate the transformer in the house anywhere. It is not by the electrical panel either. How do I go about finding it?
Thanks, carol

Could be in attic space, basement, closet, garage... they put them everywhere and anywhere.

Are you sure that it is not a battery powered wireless door bell?

I have found chime transformers INSIDE circuit breaker panelboards, even thou they do not belong there.

If you can trace the low voltage cable from the chime and/or doorbell button, it should lead you to the transformer.

Is it in the box behind the chime?
