Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

We can give it a shot. Is it just 1 door that has a problem?

Customer: replied 1 year ago.
All 3 doors connected.

Do you have a volt meter?

Generally when everything goes down it's a bad transformer or a bad connection between the trans former and the master station. Can you locate the transformer?

Is there a way to send a photo of the area on the board where the door bells are connected?

Did you get the picture?
Expert:  Rick replied 1 year ago.

Yes, I don't see a transformer in the picture. This is a pretty complicated system not a simple door chime only set up. If you can't find the transformer(s) the it's probably best to leave this to an electrician (not a handy man)

That's what my husband said. Oh well I tried.
