Understanding the Old Nutone Doorbell Wiring System

The first thing you need to do when wiring your old Nutone doorbell is to understand its wiring system. Nutone doorbells typically have two components: the doorbell button and the chime box. The doorbell button is what your visitors press when they arrive at your doorstep, and the chime box is what produces the sound that alerts you to their presence.

The wiring for your old Nutone doorbell is composed of different colored wires that connect the doorbell button to the chime box. These wires are coded with different colors to indicate their functions. It’s important to understand these color codes to ensure that you wire your doorbell correctly.

Here are the color codes for the wires in your old Nutone doorbell:

As you can see from the diagram, the red wire from the transformer connects to the white and yellow wires from the doorbell buttons, while the green wire from the chime box connects to the white and yellow wires from the buttons as well.

When the doorbell button is pressed, it sends a signal through the white or yellow wire to the chime box, which then produces a sound. If you have multiple doorbell buttons, each one is wired to its own separate set of wires.
