Chris, you are a real sharer! Thanks for the altruistic support and DIY. 👍👍👍

HI PK: Thanks - Chris

Great video. Been looking everywhere for how to connect a Rittenhouse C8538.

Hi kenneth: Glad the Video helped you with your Chime - Chris

I see what you did there "Dead Ringer". 😄

Hi Michael: To funny - Thanks - Chris

Great video but I just a Rittenhouse door chime from the 90s I cannot find a way to wire it in I got Terminal A and Terminal B what wires do I use on them and what wire do I use for the doorbell

[@northsideservicecompany3567]

Hi James: Without a Model Number of some more detailed information about your Rittenhouse Chime - I can only give you some "basic" help. The "A" and "B" Terminals are typically where the wires from the Transformer are connected (16 Volts AC @ 15-30 Watts (VA)). The wires from the Pushbuttons are usually connected - 1 wire to the "A" Terminal and the 2nd Wire to either "Front" - "Rear" or "Side". This wiring configuration for Rittenhouse 3 & 4 Tube - 8-Note Door Chimes (both Long and Short Tube models) - YMMV - Chris

Great Video. Very Helpful. I happen to have they exact same model but the transfo in the wall only gives me 10 VAC on the voltmeter. Trying to use it with batteries, but I cannot figure out the wiring of the door button (embarrassing, I know). My door button only has a 155 Ohms resistance, which drops to 0.5 Ohms when the button is pressed. I connected it all ways I could imagine but the chimes work constantly, no matter the configuration. Did you try it with 9V batteries?

[@northsideservicecompany3567]

Hi Rebecca: Your Transformer needs to be 16 Volts AC rated at a minimum of 15 Watts (30 watts is much better). The pushbutton wires are connected as follows - 1 of the 2 pushbutton wires is always connected to the "A" Terminal (regardless of if you're using s transformer or batteries) the 2nd pushbutton wire is connected to either the "Front" terminal for a Transformer - or - the "Front" terminal for Batteries . I did not try this particular Chime with batteries - I have repaired other Rittenhouse Chimes for customers who are using batteries, and they work fine. Does your Chime ring constantly without a pushbutton connected? - If it does, it needs to be repaired - Chris

@@northsideservicecompany3567 Hi Chris, I finally figured out a way to make it work, kind of. There are probably components that need servicing, including that transfo inside the wall that provides 10 VAC instead of 16. I started looking at it because the chime was working intermittently, meaning 50% of the time when there was someone at the door. The 10 VAC transfo was connected to terminals A and B and the door button to Terminal A and to the ''Front'' terminal - transfo side (right), but the unit was also powered with 2 9V batteries. (As if AC was used for the door button and 9V batteries to make the rest of the circuitry work) I found a similar interconnection diagram for a NuTone chime secure.img1-fg.wfcdn.com/docresources/971/25/250804.pdf Anyhow, I realized that when connecting the door button to the ''Front'' terminal on the 9V side (left), it would work constantly whether the door button was pressed or not - as if the voltage drop of the bulb was too low. I removed the light bulb, so now my door button is open or short (when pressed) and it works fine. Almost: there is no light at night in the door button and when pressed, all 4 chimes ring simultaneously, then the 8 tone melody plays... ...100% of the time...

[@northsideservicecompany3567]

@@ThePic1869tm i think the lack of correct voltage form the Transformer is at the heart of the problems with your Chime. Since the Chime is a solid-state device - being severely under powered will create all sorts on unusual problems - Chris

Good vidio but how did you repair the doorbell?

[@northsideservicecompany3567]

Hi Jon: I determined what was wrong with it - Replaced the bad components on the circuit board - clean the plungers and solenoids - Chris

[@bullmoose6739]

Are Emerson Rittenhouse wall radio intercoms from the 50's. I bought an older home. I just want to know the history.

[@northsideservicecompany3567]

Hi bull moose: The earliest Rittenhouse Intercom I know of is from the late 1950's - Chris

[@johnfoolen3304]

I have a fasco c8847r that looks identical. It works well but every once in a while it gives a single chime with out anything being activated.I only have the front door set up on the chime. Any thoughts on what the fix may be.

[@northsideservicecompany3567]

Hi John: Your Fasco Chime is actually a Rittenhouse Chime. Based on the information you have provided, it seems that it's time for your Chime to be rebuilt. You can contact us directly about having this done - Chris [e-mail]

Can you do a Rittenhouse 420?

[@northsideservicecompany3567]

Hi Snowie's: I don't know - I don't know anything about a Rittenhouse Model 420 - You would need to contact me directly about the Chime - Chris 925-743-8236

@@northsideservicecompany3567 well . The Rittenhouse 420 is a rare door chime I am looking for

[@davidcraig5256]

He never says HOW he fixed it. Just that it is now working. Poor. If it were not working, what made the difference. How does this help me with my problem. This is NOT a fix video.

[@northsideservicecompany3567]

Hi David: This is not labeled as a "fix it" Video - It is a Video comparing a Rittenhouse Chime to a very similar NuTone Chime. - Chris
