How to find doorbell transformer


My house was built in 1970. I have a front and back doorbell and neither one works. I replaced the doorbell button on the front but it still does not work.
I never considered a 40 year old home that old, but the more projects I get into, the more I realize this isn't always true.
I have no idea where to begin looking for the transformer box. Can you please give me some suggestions?
My husband died several years ago and I do just about all of my own home maintenance because I cannot afford to hire out but it's extremely important to me that it be done correctly.

Thanks,

lachp

How to find doorbell transformer


Years ago you could expect those things to turn up almost anywhere and even be buried in the walls somewhere in some cases. Typically they are in or around the electric panel. I have also seen them high on the wall of a closet near the front door, have no idea why that was thought to be a good idea.

Do you know what they look like?

I usually watch videos on websites like Lowes, Home Depot, Menards, You Tube, etc., so I've seen what they show which are newer models certainly, should I expect to find something similar?

My electrical panel is a joke. I really need to have a whole new breaker box put in which is top of my list when the $$ is there.
Thanks for the quick reply.

As far as I have ever seen they are all basically the same. Some are painted black some are painted grey some are plain metal finish. They should be associated with a junction box of sorts but there again not always. They will have two wires of typical house wiring attached maybe 14 gauge maybe 12 gauge. They will also have two much smaller wires attached, normally 18 gauge.

Here's some pictures of the late model types but the older ones look a little different, just depends on how old they are.

Thought I posted a reply but don't see it so I'll try again. Thanks for quick reply but my electrical system is a mess. I need to have a new circuit breaker box installed as soon as the $$$ is available.

How to find doorbell transformer


If you don't find it fastened to or near the electrical panel, and if you have a single story home, start with the area of the attic directly over the location of the buzzer. You will probably find that the wires to the buzzer go straight up the wall, to the attic, and if you can locate the low voltage wires, they should lead you to the transformer, which probably won't be far away.

It can be inside the panel, on the panel, somewhere up in the joist bay of the basement if you have one, inside a blank on the wall. Also have seen people put them up in the attic. Also start shutting off circuit breakers one at a time. When the doorbell no longer makes a sound, you know which circuit to look on.

Poke your head inside each closet, then turn around and look above the door.

How to find doorbell transformer


its one of those things that could be anywhere. I mounted mine in a spot in my attic that i thought would be fairly obvious and easy to get to, but most people don't think of the next owners. At my old house i found it underneath a floor board in the attic


Your best bet is probably just to get a wireless setup

How to find doorbell transformer


What color & size will the wires be? I found what appears to be a transformer with very thin wires, from 4 sources. Each has a green, red, yellow and black wire. It's in my furnace room which is just about the central location of both doorbells. They are all grounded together on my hot water heater.
As I stated in my original post, I have a raised ranch. My garage is under my living room with a door into my finished basement. It's hard to tell where all the wires go exactly, but would there be use for one in my garage? I have a garage door opener (w/remote) with a light.
Can you give me your thoughts please?
Thanks again,
Pam

Don't mess with that one just yet.

What type of thermostat do you have for your heat system?

How about some pictures? Got a digital camera?
