Electrical Question

Buzzing doorbell...

Noticed a loud humming/buzzing coming from my doorbell. I have
a front and rear door bell. I just figured out today that if the front
door wire and transformer wire are hooked to the chime, the front
doorbell works fine and there is no buzz. When the rear door wire
touches the rear door screw on the chime the buzzing is back. When
I removed the rear button the rear/transformer hookup still buzzes.
Help! Thank you for your time and knowledge!

From what you describe it sounds aif if the transformer for the doorbell has either been short circuited or is overloaded due to the circuit impedance of two bells?
