OK...doorbell went out. Changed the doorbell button...no luck. Changed the chime...no luck. Transformer is dead but I can't find it! It's not in the garage and I have a finished basement so I can't see up in the ceiling. I'm afraid the previous owner maybe closed it in when they finished the basement. I also looked in the attic but there's about 10 inches of blown in insulation and you can't see anything. I fished around and followed all the wires I could find but no luck.
Any ideas of where this thing might be hidden? I thought they were typically located in the basement.

Should I be worried about a dead transformer sitting somewhere? The 16V secondary side is dead but it would still have 120V going to it. Of course whatever circuit it's on would have a breaker behind it.

I guess I'll have to get a wireless one if I want a doorbell.

It might be helpful to remove the chime from the wall and look to see if the wires go up or down inside the wall. That will give you a clue where to go next.

Thanks for the reply.

I was able to find some wires that matched those coming out of the wall at the chime stuffed up in the ceiling in my furnace closet in the basement. As it turns out, the transformer was attatched to the switch box on my OLD furnace which I had replaced about a month ago. The furnace guys must not have known what it was for and just cut the wires and threw the transformer away with the old furnace.

My house was built in 1995. The doorbell quit working 8-10 years ago. I initially couldn't find the transformer and decided for the time being, it was okay for people to just knock on the door. Fast forward, it's 2015 and I finally decided to get the doorbell working. I have two outdoor buttons, neither were lit. I looked in the attic, crawlspace, closets--everywhere, no transformer. After going online and seeing what others have said about possible locations, I located it underneath the main service panel cover--not inside where you access the breakers; I had to take the whole service panel cover off the wall. One wire had become disconnected from the transformer. Hooked it up--both doorbell buttons lit up and they both work now.

Inside the panel are labels that indicate which breaker goes with what circuit for various rooms of the house. The one for the doorbell was not labeled--so I labeled it. I also took a black Sharpie and wrote the location of the transformer on the inside of the bell cover--seems like that would have been a logical thing for the installer to have done in the first place.

Wow, I’ve lived in my house for 10+ years and gave up along time ago on finding my old transformer. I’m pretty mad at the builder for making me look so hard, but I found it thanks to your blog. It was behind the electrical panel after all, but attached to the outside of the box, behind the drywall. Jeesh, I’m pretty handy sometimes but I could live without the hide and seek. Guess the black and green wire leaving the inside top of my box should have been a clue. Thanks Bob Vila.

try a circuit testing: at the bell both wires go to the transformer thru the switch, close the circuit try a tone generator

I have same problem with Mike. I cannot locate the transformer. The old home owner didn't label anything for door bell either on main circuit. I would like to replace but unsure where to look

We have been looking for our doorbell transformer for a long time in our home built in 1999. We just found it in the crawlspace attached to the furnace.
