Installation Steps:
- Disconnect Power: Before starting, turn off the power to your doorbell system at the circuit breaker to prevent electrical shock.
- Remove Old Chime: Carefully remove the cover of your existing doorbell chime. Disconnect the wires from the old chime mechanism, noting which wire was connected to each terminal (e.g., Front, Rear, Transformer). It is recommended to label the wires if unsure.
- Mount New Chime: Position the new Broan-NuTone chime mechanism in the desired location. Secure it using appropriate screws (not included) through the mounting holes.
- Connect Wiring: Refer to the wiring diagram on the chime mechanism and the image below. Connect the wires from your doorbell system to the corresponding terminals on the new chime:
- TRANS: Connect the wire from your doorbell transformer to this terminal.
- FRONT: Connect the wire from your front doorbell push button to this terminal.
- REAR: Connect the wire from your rear or side doorbell push button to this terminal (if applicable).
Warning: Ensure all connections are secure and wires are not frayed or exposed.
- Restore Power: Once all connections are secure, replace the chime cover (if applicable) and restore power to the doorbell system at the circuit breaker.
- Test Operation: Press your doorbell buttons to verify proper operation.

Operating Instructions
The Broan-NuTone Doorbell Chime Mechanism provides distinct sounds for different entry points:
- Front Door: When the front doorbell button is pressed, the chime will produce a classic two-note "Ding Dong" sound.
- Rear or Side Door: If a rear or side doorbell button is connected to the "REAR" terminal, pressing it will produce a single "Dong" sound.
Ensure your doorbell buttons are functioning correctly for optimal chime operation.
Maintenance
Regular maintenance is minimal for this doorbell chime mechanism. If the plungers appear to be sticking or the chime sound is inconsistent, follow these steps:
- To Clean Sticking Plungers: Place a few drops of non-flammable cleaning fluid onto the plungers. Gently activate the plungers repeatedly until they move freely.
- Do Not Oil Plungers: It is crucial not to use oil on the plungers, as this can attract dust and debris, leading to further sticking and malfunction.
For general cleaning, wipe the exterior of the chime mechanism with a dry, soft cloth. Do not use abrasive cleaners or solvents.
