Rittenhouse Service & Repair Forum
I am a property manager who manages a townhome with a broken Rittenhouse intercome system. The speakers on the exterior are installed in the brick so to remove them is a huge project. The main console in the kitchen is what I am looking to repair or replace. The model number is: (looks like) M7034. The serial number looks like 202 1-9864-9989. Please feel free to call me at 630-879-3680 as I am working on a very short time frame. Thank you for your time in this matter!M. Berrt

The small piston that strikes the chime does not return back to the original position. There is a spring on the piston. It seems like the piston should have a retainer of some sort on the end to hold the spring in place.
