Before we dive into the installation, let’s talk about why this upgrade matters. Ring Video Doorbell 2 is a smart device that needs consistent power to stream video, send alerts, and stay connected to Wi-Fi. Unlike traditional doorbells that just ring a chime, Ring 2 uses power continuously. Most older doorbell systems use transformers that output 8 to 16 volts AC (alternating current). But Ring 2 requires **16 to 24 volts AC** to function properly. If your current transformer is underpowered, your Ring 2 may not charge fully, lose connection, or fail to record events.
Upgrading to a compatible transformer ensures your doorbell gets the juice it needs. It’s a simple fix that can solve a lot of frustrating issues. Plus, it future-proofs your setup if you ever add more smart devices to your doorbell system.
Tools and Materials You’ll Need
Before you start, gather these tools and materials. Having everything ready will make the process smoother and safer.
- New doorbell transformer (16-24V AC, 20-30VA recommended)
- Voltage tester or multimeter
- Wire strippers
- Screwdrivers (flathead and Phillips)
- Electrical tape
- Wire nuts (usually included with the transformer)
- Electrical junction box (if not already installed)
- Drill and bits (if mounting a new box)
- Safety gloves and goggles
You can find compatible transformers at most hardware stores or online. Look for brands like Nutone, Heath Zenith, or Ring’s own transformer. A 16V 30VA transformer is a popular choice for Ring 2.
Step 1: Turn Off the Power
Safety first! Working with electricity can be dangerous, so always turn off the power before touching any wires.
Locate Your Circuit Breaker
Go to your home’s main electrical panel (breaker box). Look for the breaker labeled “doorbell,” “chime,” or “front door.” If you can’t find it, turn off the main breaker to cut power to the entire house. This is the safest option.
Test the Power
Use a voltage tester or multimeter to confirm the power is off. Touch the tester to the doorbell wires at the chime or transformer location. If the tester doesn’t light up or beep, the power is off. If it does, double-check your breaker and try again.
Never skip this step. Even low-voltage systems can cause shocks or damage your Ring device.
Step 2: Locate Your Current Transformer
The transformer is usually hidden in one of three places:
- Inside the doorbell chime unit (most common)
- In an electrical junction box near the chime
- Inside the wall near the doorbell button
To find it, remove the cover of your doorbell chime. You’ll see two or more wires connected to terminals. One pair leads to the doorbell button, and another pair connects to the transformer. The transformer itself looks like a small metal box with wires coming out.
If you can’t find it, check near your furnace, in the basement, or in a utility closet. Some older homes have transformers tucked away in hard-to-reach spots.
Step 3: Check Your Current Transformer’s Voltage
Now, let’s see if your current transformer is up to the task.
Use a Multimeter
Set your multimeter to AC voltage (usually marked as “V~”). Touch the red probe to the transformer’s output terminal and the black probe to the other. The reading should be between 8 and 16 volts for most old transformers.
If it’s below 16V, your Ring 2 isn’t getting enough power. Time to upgrade.
Look for Labels
Check the transformer for a label that says “16V” or “24V.” If it says “8V” or “12V,” it’s underpowered. Even if it says “16V,” it might not deliver enough current (measured in VA). Ring recommends at least 20VA, but 30VA is better for consistent performance.
Step 4: Choose the Right Replacement Transformer
Not all transformers are created equal. Here’s what to look for:
- Voltage: 16V or 24V AC
- Current: 20-30VA (volt-amperes)
- Compatibility: Works with mechanical or digital chimes
- Mounting: Fits in your existing junction box or chime housing
A 16V 30VA transformer is ideal for most Ring 2 installations. It provides enough power without overloading the system. Avoid transformers labeled “electronic” or “digital-only” unless your chime is digital.
You can buy a transformer online or at a hardware store. Ring sells a compatible transformer on their website, but third-party options work just as well.
Step 5: Remove the Old Transformer
Now it’s time to swap out the old transformer.
Disconnect the Wires
Carefully unscrew the wires connected to the transformer. There are usually two wires: one from the doorbell button and one from the chime. Take a photo or label them so you know where they go later.
Unscrew the Transformer
Most transformers are held in place by screws or clips. Remove them and gently pull the transformer out of the junction box or chime housing.
Be careful not to damage the wires or surrounding components.
Step 6: Install the New Transformer
With the old transformer out, it’s time to install the new one.
Mount the Transformer
Place the new transformer in the same location. If it doesn’t fit, you may need to install a new junction box. Use screws to secure it in place.
Connect the Wires
Attach the wires to the new transformer’s terminals. Most transformers have two terminals labeled “Front” and “Trans” or “Line” and “Load.” Connect the wire from the doorbell button to one terminal and the wire from the chime to the other. Tighten the screws securely.
If your transformer has wire leads instead of terminals, use wire nuts to connect the wires. Strip about 1/2 inch of insulation from each wire, twist them together, and cover with a wire nut. Wrap with electrical tape for extra security.
Secure the Wires
Tuck the wires neatly into the junction box or chime housing. Avoid pinching or bending them sharply.
Step 7: Restore Power and Test
Now for the moment of truth.
Turn the Power Back On
Go back to your breaker box and turn the power back on. If you turned off the main breaker, turn it on first, then the doorbell breaker.
Test the Voltage
Use your multimeter to check the voltage at the transformer output. You should see 16-24V AC. If it’s within range, great! If not, double-check your connections.
Test the Doorbell
Press your doorbell button. The chime should ring. If it doesn’t, check the wiring again.
Set Up Your Ring 2
Open the Ring app and follow the setup instructions. The app will detect the doorbell and guide you through connecting to Wi-Fi. If everything is working, you should see a live view and receive motion alerts.
Troubleshooting Common Issues
Even with careful installation, problems can happen. Here’s how to fix the most common ones.
Doorbell Doesn’t Ring
- Check that the power is on.
- Verify the wires are connected correctly.
- Test the transformer voltage.
- Make sure the chime is set to the right mode (mechanical vs. digital).
Ring 2 Shows “Low Battery”
- Ensure the transformer is outputting at least 16V.
