The small piston that strikes the chime does not return back to the original position. There is a spring on the piston.

Is there supposed to be a retainer on the end of the piston to keep the spring …Purchase or Repair: Ticket Image...

It appears the hammers are sticking or a spring has broken. There are three. Can i get replacement solenoids/hammers, or an estimate to repair the whole Chime unit. Also if you think it would be best to buy new.Thank you.,John

My manual says 4-8 Note Chime Models (534, 535, 552, 577, 618, 633). I don't know which one I have. It has long chime tubes and a clock on top. The door bell works great, but the clock doesn't.

I bought a house built in 1950 with an old Rittenhouse door chime, Model #365. I have no idea if it can be repaired. I don\'t have the front door button. The inner workings are very dirty. Do you think it\'s worth sending to you? Thanks, Kathie

I moved this door chime/clock when it was working from one home to another. The electrician that hooked it up did not do it correctly and I have no schematic for how it should be wired. I know it needs three wires but not sure on which of the 7 screws they get wired to. They do not indicate Com or T…Purchase or Repair: Ticket Image...
