I'm in the process of trying to repair my Emerson C8578 doorbell with four chimes. It has two push buttons...one side door and the other for the front door. The side door chime was working until this week. Then, it stopped with just a constant buzz. Now, there's no sound at all.
I replaced both buttons and got lighted results on both the side and front doors. Initially, I got two chime sound from the side door, then nothing from either door.
The problem does not seem to be the transformer. since the the lights are working fine on both replaced buttons. I have tried re-wiring but I'm not getting any sound at all. I'm not sure that the wiring is correct or whether the chimes are shot or the plungers are stuck.
I can't locate the manual so I'm sort of working the dark on this repair. Hopefully, your techs can steer me in the right direction to restore this system or maybe they can repair it for me.
I would appreciate a response in this matter as soon as possible.
