Pro Tip: If your existing doorbell chime is mechanical (not digital), you may also need the Ring Chime Connector. This small device ensures your indoor chime works properly with the Ring doorbell, especially if your transformer voltage is on the lower end.
Step 1: Turn Off the Power
Safety comes first. Working with electrical wiring can be dangerous if the power is still on. Even though doorbell circuits operate at low voltage, they’re still connected to your home’s electrical system and can pose a shock risk.
Locate Your Doorbell Transformer
The doorbell transformer is usually found in one of these locations:
- Near your main electrical panel or breaker box
- In the basement or crawl space
- Inside the attic
- Behind the existing doorbell chime inside your home
Transformers step down your home’s 120V AC power to a safer 8–24V AC for the doorbell. Look for a small gray or black box with two wires coming out—those are your doorbell wires.
Turn Off the Correct Circuit Breaker
Once you’ve located the transformer, find the corresponding circuit breaker in your electrical panel. It may be labeled “doorbell,” “chime,” or “low voltage.” If not, you may need to test breakers one by one.
Turn off the breaker and use a non-contact voltage tester to confirm that power is off at the doorbell location. Touch the tester near the wires—if it doesn’t beep or light up, you’re safe to proceed.
Important: Never assume the power is off. Always test it.
Step 2: Remove the Old Doorbell
Now that the power is off, it’s time to remove your existing doorbell.
Unscrew the Old Doorbell Unit
Use a screwdriver to remove the screws holding your old doorbell to the wall. Gently pull the unit away from the wall. You should see two wires connected to the back—these are your existing doorbell wires.
Disconnect the Wires
Loosen the terminal screws on the back of the old doorbell and carefully remove the wires. Don’t let them fall back into the wall. You can tape them to the wall temporarily or hold them with a clip to keep them accessible.
Take note of which wire goes to which terminal (usually labeled “Front” and “Trans”), though for most Ring installations, the polarity doesn’t matter.
Inspect the Wires
Check the condition of the wires. Are they frayed, corroded, or brittle? If so, you may need to trim them and strip fresh ends. Healthy wires should have clean, copper ends and intact insulation.
If the wires are too short or damaged, you might need to run new ones—but in most cases, existing wiring is sufficient.
Step 3: Test the Voltage
Before connecting your Ring doorbell, you must confirm that your existing doorbell system provides the correct voltage.
Set Up Your Multimeter
Set your multimeter to measure AC voltage (usually marked as “V~” or “ACV”). Insert the red probe into the “V” or “Ω” port and the black probe into the “COM” port.
Test the Wires
Touch one probe to each of the doorbell wires (it doesn’t matter which is which). The multimeter should display a voltage reading.
- Ideal range: 16–24V AC
- Minimum for Ring: 8V AC (but performance may suffer)
- Too high: Over 24V can damage the Ring doorbell
If your voltage is below 8V, your Ring doorbell may not work reliably—especially if you have a mechanical chime. In this case, you may need to upgrade your transformer or use the Ring Chime Connector.
Example: If your multimeter reads 12V, that’s acceptable but on the lower end. Consider using the Chime Connector to boost performance.
Step 4: Prepare the Wires
Proper wire preparation ensures a solid connection and prevents loose wires from causing issues later.
Strip the Wire Ends
Use wire strippers to remove about 1/4 inch (6 mm) of insulation from each wire end. This exposes fresh copper for a better connection.
Avoid cutting too much insulation—you don’t want bare wire sticking out beyond the terminal.
Twist the Strands (if stranded wire)
If your wires are stranded (multiple thin copper strands), gently twist them together with your fingers or pliers. This prevents stray strands from causing short circuits.
Straighten the Wires
Make sure the stripped ends are straight and not bent. This helps them fit securely into the Ring doorbell terminals.
Step 5: Connect the Wires to the Ring Doorbell
Now it’s time to attach your existing wires to the new Ring doorbell.
Identify the Terminals
On the back of your Ring doorbell, you’ll see two small terminal screws or slots labeled “Front” and “Trans.” These correspond to the two wires from your doorbell system.
Insert the Wires
Loosen the terminal screws slightly. Insert one wire into each terminal and tighten the screws securely. Make sure the copper is fully under the screw and not exposed.
Pro Tip: If the screws are tight, use a small flathead screwdriver to gently pry them open before inserting the wire.
Double-Check Connections
Give each wire a gentle tug to ensure it’s secure. Loose wires are a common cause of doorbell malfunctions.
Step 6: Mount the Ring Doorbell
With the wires connected, it’s time to mount the doorbell to your wall.
Choose the Right Mounting Bracket
Ring doorbells come with different mounting brackets:
- Standard bracket: For flat surfaces
- Wedge bracket: For angled mounting (improves camera view)
- Corner bracket: For corner installations
Select the one that best fits your door and wall setup.
Position the Bracket
Hold the bracket against the wall where you want to install the doorbell. Use a level to ensure it’s straight. Mark the screw holes with a pencil.
Drill Pilot Holes (if needed)
If you’re drilling into brick, stucco, or concrete, use a drill to create pilot holes. Insert wall anchors if necessary.
Secure the Bracket
Screw the bracket into place using the provided screws. Make sure it’s tight and stable.
Attach the Doorbell
Slide the Ring doorbell onto the bracket until it clicks into place. Some models have a security screw to prevent theft—install it now.
Step 7: Turn the Power Back On
Now that everything is connected and mounted, it’s time to restore power.
Flip the Breaker Back On
Go to your electrical panel and turn the doorbell circuit breaker back on.
Wait for the Doorbell to Power Up
The Ring doorbell will take a few seconds to boot up. You should see a light on the front (usually white or green) indicating it’s receiving power.
Check the Ring App
Open the Ring app on your smartphone. The app should detect the new device and guide you through setup.
Follow the on-screen instructions to connect to Wi-Fi, name your doorbell, and adjust settings like motion zones and alerts.
Step 8: Test the Doorbell
Before calling the job done, test everything to ensure it’s working properly.
Test the Video and Audio
Press the doorbell button (or simulate a press in the app). Check that:
- You receive a notification on your phone
- The video feed loads quickly
- You can hear and speak through the doorbell
Test the Chime
If you have an indoor chime, make sure it rings when the button is pressed. If it doesn’t, you may need the Ring Chime Connector.
Check Motion Detection
Walk in front of the doorbell to test motion alerts. Adjust sensitivity in the app if needed.
Troubleshooting Common Issues
Even with careful installation, problems can arise. Here’s how to fix the most common issues.
