Hello,
I am restoring an old house and am trying to get the original doorbell/door chime to work. I replaced some old wires and tested the transformer with a multitester. It outputs 10+ volts as rated, and I get 10+ volts at the chime terminals when the doorbell is pushed. It just doesn't ring, which leads me to assume the chime is the problem. Does anyone know where I could get replacement parts for the chime. Any suggestions for the most likely malfunctioning part? Here's a pic of the chime.

Actually I would call this more of a "doorbell/buzzer" than a "chime". It's very similar to the one that was in my Grandparents house. Are you getting 10+/- volts at the two screws that are above the two coils in the picture? If you are, a problem with the coils are the most likely culprit at this point. Can you move the clapper arm manually? If you can watch to see if the two plungers within the coils are moving also, they should be. You might try to spray something like WD-40 on the plungers as you move the clapper arm back/forth to free them. There is also a good chance a coil or both coils have gone bad. Not much you can do there. You can still buy this type "bell/buzzer" at most big box stores, I put one similar to that one in my shop, although I'm thinking it was 12vDC. Good Luck, David
