- User manual: Always refer to the specific manual for your model—download it from nutone.com if you don’t have it.
- Ladder (if needed): For reaching high-mounted chime boxes.
Having these tools ready will save you time and frustration. And remember: safety first. Always turn off the power at the breaker before handling any electrical components.
Step 1: Identify Your Nutone Doorbell Model
Not all Nutone doorbells are programmed the same way. The first step is to figure out which model you have. Common models include:
- IS453: A basic wired chime with two notes (ding-dong).
- IS455: A dual-tone chime with multiple melody options.
- IS460: A wireless doorbell system with programmable tones.
- IS480: A video doorbell with chime integration.
To find your model number, look on the back or side of the chime unit inside your home. It’s usually printed on a label. If you can’t find it, check the original packaging or receipt.
Why does the model matter? Because programming methods vary. For example, the IS455 uses dip switches to select tones, while the IS460 uses a programming button. Knowing your model ensures you follow the correct steps.
Step 2: Turn Off the Power
This step is non-negotiable. Always turn off the power at the circuit breaker before working on your doorbell system. Even though doorbell voltage is low (usually 16V), it’s still electricity—and safety should always come first.
Here’s how to do it safely:
Locate the Correct Breaker
Doorbell circuits are often labeled “Doorbell,” “Chime,” or “Transformer” in your electrical panel. If you’re unsure, turn off the main breaker to be safe.
Test the Power
Use a non-contact voltage tester to check the wires at the chime unit. Touch the tester to the terminals—if it beeps or lights up, power is still on. Wait until it shows no voltage.
Label the Breaker (Optional but Helpful)
If your breaker isn’t labeled, use a piece of tape to mark it. This makes future maintenance easier.
Once the power is off, you’re ready to begin.
Step 3: Remove the Old Chime (If Applicable)
If you’re replacing an old doorbell, you’ll need to remove it first. Here’s how:
Unscrew the Cover
Most Nutone chimes have a front cover held by one or two screws. Remove them and gently pull the cover off.
Disconnect the Wires
You’ll see two or three wires connected to terminals labeled “Front,” “Trans,” and sometimes “Rear.” Loosen the screws and carefully pull the wires free. Take a photo or label them so you remember where they go.
Remove the Old Unit
Unscrew the mounting bracket and take the old chime out of the wall box.
Now you’re ready to install the new Nutone doorbell.
Step 4: Install the New Nutone Doorbell Chime
Installing the chime unit is straightforward. Follow these steps:
Mount the Bracket
Hold the new chime’s mounting bracket against the wall. Use a level to make sure it’s straight, then mark the screw holes. Drill pilot holes if needed and secure the bracket with screws.
Connect the Wires
Reconnect the wires to the correct terminals:
- Front: Connects to the front door push button.
- Trans: Connects to the transformer (usually located near your furnace or breaker panel).
- Rear (if present): For a second doorbell button (e.g., back door).
Twist the wire ends to prevent fraying, then insert them under the terminal screws and tighten securely. Don’t over-tighten—just enough to hold the wire firmly.
Attach the Chime Unit
Slide the chime onto the mounting bracket until it clicks into place. Replace the front cover and secure it with screws.
Step 5: Install or Check the Transformer
The transformer steps down your home’s 120V power to the 16V needed for the doorbell. Most Nutone systems require a 16V, 10VA or 15VA transformer.
Locate the Transformer
It’s usually found in your basement, garage, or near the furnace. It looks like a small black box with wires coming out.
Check the Voltage
Use a multimeter to test the output. Set it to AC voltage and touch the probes to the transformer terminals. You should see around 16V. If it’s too low (under 14V), the chime may not work properly. If it’s too high (over 20V), it could damage the chime.
Replace if Necessary
If your transformer is old or underpowered, replace it with a compatible 16V model. Turn off the power, disconnect the old one, and install the new one following the same wiring.
Step 6: Install the Doorbell Button
Now it’s time to install the push button at your front (and rear, if applicable) door.
Choose the Right Location
Mount the button about 48 inches above the ground, within easy reach. Avoid direct sunlight or areas prone to moisture.
Connect the Wires
Run two low-voltage wires from the chime to the button location. Strip about 1/4 inch of insulation from each end. Connect one wire to each terminal on the button (polarity doesn’t matter). Secure with screws.
Mount the Button
Use the included screws to attach the button to the wall. Make sure it’s flush and secure.
Step 7: Program the Chime Tone
This is where the magic happens—choosing your favorite doorbell sound. The method depends on your model.
For Models with Dip Switches (e.g., IS455)
Open the chime cover and look for a small set of dip switches (tiny sliders) inside. These control the melody.
- Switch 1: On = Melody A, Off = Melody B
- Switch 2: On = High volume, Off = Low volume
- Switch 3: On = Dual-tone, Off = Single-tone
Refer to your manual for the exact switch settings. For example, to get a classic “ding-dong” with medium volume, you might set Switch 1 to Off, Switch 2 to Off, and Switch 3 to On.
For Wireless Models (e.g., IS460)
Wireless Nutone doorbells use a programming button instead of dip switches.
- Press and hold the “Program” button on the chime unit for 3 seconds.
- The chime will beep, indicating it’s in programming mode.
- Press the doorbell button. The chime will play a tone.
- Press the button again to cycle through available tones.
- When you hear the tone you like, press and hold the button for 3 seconds to save it.
Some models allow you to assign different tones to different buttons (e.g., front door = melody, back door = single chime).
For Smart Doorbells (e.g., IS480)
If you have a video doorbell, programming may involve a mobile app. Download the Nutone app, connect the doorbell to Wi-Fi, and follow the on-screen prompts to select chime tones and notifications.
Step 8: Restore Power and Test the System
Once everything is connected and programmed, it’s time to test.
Turn the Power Back On
Go to your breaker panel and flip the doorbell circuit back on.
Ring the Doorbell
Press the button and listen. You should hear a clear, consistent chime. If it’s weak or silent, check the wiring and transformer voltage.
Test All Buttons
If you have multiple buttons (front and rear), test each one to ensure they trigger the correct tone.
Adjust Volume (If Needed)
Some models have a volume control dial inside the chime unit. Turn it to increase or decrease the sound level.
Troubleshooting Common Issues
Even with careful installation, problems can happen. Here’s how to fix the most common ones.
Doorbell Doesn’t Ring
- Check the power: Confirm the breaker is on and the transformer is outputting 16V.
- Inspect wires: Loose or corroded connections can break the circuit. Re-tighten all terminals.
- Test the button: Use a multimeter to check continuity. If the button is faulty, replace it.
Chime Sounds Weak or Intermittent
- Low voltage: The transformer may be underpowered or failing. Replace it with a 16V, 15VA model.
- Long wire runs: If wires are very long, voltage drop can occur. Use thicker gauge wire (18 AWG or lower).
Wrong Tone Plays
- Reset dip switches: Double-check the switch positions against the manual.
- Reprogram wireless units: Enter programming mode again and select the correct tone.
Chime Rings Randomly
- Loose wiring: A frayed or loose wire can cause false triggers. Inspect and secure all connections.
- Faulty button: A worn-out button may short circuit. Replace it.
No Sound at All
- Blown fuse: Some chime units have an internal fuse. Check the manual and replace if needed.
- Defective chime: If all else fails, the chime itself may be faulty. Contact Nutone support or replace the unit.
