Connecting ring doorbell 2 to existing 16vac doorbell

I cannot get my pre-existing doorbell to ring after connecting our current electrical.
We have a 16volt AC unit. I believe it’s mechanical. It hasn’t worked for so long I don’t even remember what it sounds like!!

Hey @Vnlarablack! If this worked before, and is not working now, please ensure the wiring is properly connected to the chime, the Doorbell, and the transformer. I recommend also checking our Chime Compatibility list to ensure it is compatible. Try also flipping the wires on the back of the Video Doorbell to see if this improves functionality. I hope this helps! :slight_smile:
