Similiar issue, my doorbell kept sticking. So I replaced the sticky button but now my springs inside the bell housing seem to be sprung and unable to move the plunger the full range to ring or retract.

We installed our Rittenhouse intercom system in 1978 when we built our new home. The speakers look out of date and would like a better main unit. We have 4 outside units, and 7 speakers.Can we purchase new units and still use the same wiring? Would appreciate a response ASAP. Thanks Jim MannP.S. Ple…Purchase or Repair: Ticket Image...

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.

Can you repair the solo kids on this 1950s era doorbell?It’s generally ok except that some of the parts that slide in the tubes to ring the chimes are lost. I could send it in or you could sell me the parts to fix it myself. Thanks,George Pond

The Rittenhouse door intercom answering system system was installed in 1978. It is not functioning well. Do you have a newer replacement for it that would still have the doorbell and intercom system? Does a new unit come with the exterior speaker?
