Before jumping into the installation, it’s important to understand why the diode is necessary.
The Ring Video Doorbell 2 is designed to work with both battery and hardwired power sources. When hardwired, it draws power from your home’s existing doorbell transformer. However, older mechanical chimes (the kind with physical clappers and bells) can create a small electrical feedback loop when the doorbell button is pressed.
This feedback—called “back-voltage”—can confuse the Ring Doorbell 2, causing it to think the button is being pressed repeatedly. The result? Your chime might ring randomly, or your Ring app might show false alerts. Worse, over time, this can strain the doorbell’s internal components and shorten its lifespan.
That’s where the diode comes in.
A diode is a small electronic component that allows electricity to flow in only one direction. By installing it across the chime terminals, it blocks the reverse current that causes the feedback loop. This protects your Ring Doorbell 2 and ensures your chime only rings when you actually press the button.
Note: If you have a digital or electronic chime (like those found in newer homes or smart chimes), you likely don’t need a diode. These chimes are designed to handle the low-voltage signals from smart doorbells without issues. But if you have a traditional mechanical chime—especially one with a physical bell or hammer—then installing the diode is strongly recommended.
Tools and Materials You’ll Need
Before you begin, gather the following tools and materials:
- Ring Video Doorbell 2 (with included diode)
- Screwdriver (typically a Phillips #2)
- Wire strippers (if your wires need trimming)
- Electrical tape or wire nuts (optional, for securing connections)
- Voltage tester (optional, but recommended for safety)
- Ladder (if your doorbell is mounted high)
Most of these items come with your Ring Doorbell 2 kit, but it’s good to double-check. The diode is usually included in the box—it’s a small, cylindrical component with a stripe on one end. If you can’t find it, you can purchase a compatible 1N4007 diode from any electronics store or online retailer.
Step 1: Turn Off the Power
Safety first! Before touching any wires, you must turn off the power to your doorbell.
Locate Your Circuit Breaker
Head to your home’s main electrical panel (usually in the basement, garage, or utility closet). Look for the breaker labeled “Doorbell,” “Front Door,” or something similar. If there’s no label, you may need to test breakers one by one.
Turn Off the Breaker
Switch the breaker to the “OFF” position. To be extra safe, use a non-contact voltage tester to confirm that power is off at the doorbell wires. Simply touch the tester to the wires—if it doesn’t beep or light up, you’re good to go.
Pro Tip: Place a piece of tape over the breaker switch with a note like “DO NOT TURN ON – WORKING ON DOORBELL.” This prevents someone else from accidentally restoring power while you’re working.
Step 2: Remove Your Existing Doorbell
Now that the power is off, it’s time to remove your old doorbell.
Unscrew the Faceplate
Use your screwdriver to remove the screws holding the existing doorbell button in place. Gently pull the button away from the wall to expose the wires underneath.
Disconnect the Wires
You’ll see two wires connected to the back of the button—usually labeled “Front” and “Trans.” Loosen the screws or release the clips holding these wires, and carefully pull them free.
Secure the Wires
To prevent them from slipping back into the wall, twist the exposed ends together or tape them to the wall with electrical tape. This keeps them accessible for the next steps.
Step 3: Install the Diode Across the Chime Terminals
This is the most critical part of the process. The diode must be installed at the chime unit inside your home, not at the doorbell button.
Locate Your Doorbell Chime
Your chime is usually mounted on a wall near the front door, often in a hallway or entryway. It’s a small box with wires coming out of the back. Open the cover to reveal the internal terminals.
Identify the “Front” and “Trans” Terminals
Inside the chime, you’ll see several terminals. Look for the ones labeled “Front” and “Trans” (short for “Transformer”). These are the two terminals that connect to your doorbell button.
Connect the Diode
Take the diode from your Ring kit. Notice the stripe on one end—this indicates the cathode (negative) side.
– Connect the striped end of the diode to the “Front” terminal.
– Connect the non-striped end to the “Trans” terminal.
You can twist the diode’s leads around the terminal screws or use wire nuts if needed. Make sure the connections are tight and secure.
Important: The diode must be installed in the correct direction. If you reverse it, it won’t block the back-voltage and your chime may still ring randomly.
Secure the Connections
Once the diode is in place, double-check that both ends are firmly attached. Use electrical tape to cover any exposed wire if necessary. Close the chime cover when done.
Step 4: Prepare the Doorbell Wires
Now that the diode is installed, it’s time to prepare the wires at the doorbell location.
Strip the Wire Ends (If Needed)
If the exposed ends of your doorbell wires are too short or frayed, use wire strippers to remove about 1/4 inch of insulation. This ensures a clean connection to the Ring Doorbell 2.
Twist the Wires
Gently twist the bare copper strands to keep them neat and prevent stray wires.
Step 5: Mount the Ring Video Doorbell 2
With the diode in place and wires ready, you can now install your Ring Doorbell 2.
Attach the Mounting Bracket
Use the included screws to secure the mounting bracket to the wall. Make sure it’s level and positioned at the recommended height (about 48 inches from the ground).
Connect the Wires
Thread the doorbell wires through the back of the Ring Doorbell 2. Connect them to the two terminals on the back of the device—it doesn’t matter which wire goes where, as the diode handles polarity.
Secure the Doorbell
Slide the Ring Doorbell 2 onto the mounting bracket until it clicks into place. Tighten the security screw at the bottom to prevent tampering.
Step 6: Restore Power and Test the System
You’re almost done! Now it’s time to test everything.
Turn the Power Back On
Return to your circuit breaker and switch the doorbell breaker back to the “ON” position.
Wait for the Doorbell to Power Up
The Ring Doorbell 2 will take a few seconds to boot up. You’ll see the light ring flash blue, then settle into a steady color.
Test the Doorbell
Press the button on your Ring Doorbell 2. You should hear your chime ring clearly—and only once per press.
Check the Ring App
Open the Ring app on your phone. You should receive a notification that someone rang the doorbell. The live view should activate, and you should be able to speak through the doorbell if needed.
If everything works as expected, congratulations—you’ve successfully installed your Ring Video Doorbell 2 with the diode!
Troubleshooting Common Issues
Even with careful installation, you might run into a few hiccups. Here’s how to fix the most common problems:
Chime Rings Randomly
If your chime still rings without anyone pressing the button, double-check the diode installation. Make sure it’s connected to the correct terminals and oriented properly (stripe to “Front”). Also, ensure the wires aren’t loose or touching each other.
Doorbell Won’t Power On
If the Ring Doorbell 2 doesn’t light up or respond, verify that the power is on at the breaker. Use a voltage tester to check if the transformer is delivering 8–24 volts AC. If not, the transformer may be faulty and need replacement.
Weak or Intermittent Signal
Poor Wi-Fi signal can cause lag or disconnections. Make sure your doorbell is within range of your router. Consider using a Wi-Fi extender if needed.
False Alerts in the App
If you’re getting motion alerts when no one is there, adjust the motion zones in the Ring app. You can also reduce sensitivity or enable “People Only” mode to filter out animals or moving shadows.
Maintenance Tips for Long-Term Performance
To keep your Ring Video Doorbell 2 running smoothly:
- Clean the lens monthly: Use a soft, dry cloth to wipe away dust and debris.
- Check battery level: If using battery mode, recharge or replace the battery every 6–12 months.
- Update firmware: The Ring app will notify you when updates are available—install them promptly.
- Inspect wiring annually: Ensure connections at the chime and doorbell remain tight and corrosion-free.
