Doorbell issue

We have a Desa TR-0081-BX doorbell. It has a switch on two doors, the front and off the kitchen. The front- it only chimes if you hold the button down and sometimes not even then. The kitchen one doesn't seem to do anything right now. I guess the question is- "How do I fix this so it chimes?" I saw a post on Fixya that says you need some sort of diode; we do not have that.
I don't even care as much if the kitchen one works, people don't approach the house from that side.
The other question would be- can we just slap another unit in the same spot and the buttons will work with it? It's got 3-wires attached to it.

Did you change the transformer? More modern chimes require a 17 volt transformer.

I haven't changed anything, it came with the house.

Try measuring voltages with the switch depressed. Use a multimeter and measure first between common and front then common and back. Measure voltage when someone presses the button with the wires connected then with the wires disconnected. You should get ~17v AC.

Did it ever work correctly?

Maybe the switch (pushbutton ) is worn out.
Maybe there are loose connections.

Waiting for someone to come by with voltmeter. Found transformer in basement- red wire is not connected, not sure where it should go.

A picture would help us see what you're looking at. See How To Include Pictures.

The picture is not of a standard electro mechanical door chime commonly found in homes. It appears to be some sort of electronic device. Can you remove the cover so we can see inside.

What is the secondary voltage stamped into the transformer?
