8 Methods to Fix Nest Doorbell No Power Right Away
Below are eight solutions to fix your Nest doorbell problem. Follow them carefully.
#1: Ensure Your Doorbell is Connected to a Power Source
The first thing you should do is check if your Nest doorbell is connected to a power source. Depending on the model of your device, there are different ways to do this.
Wired Nest Doorbell
A wired Nest doorbell should be connected to your home’s doorbell system and transformer.
To ensure your connection is working, follow these steps:
- Check your chime box for compatibility labeling.
- Install the included chime connector if you don’t find the label.
- Check the wiring for any damage, corrosion, or loose connections.
Battery-powered Nest Doorbell
A battery-powered Nest doorbell should have an internal rechargeable battery that lasts several months on a single charge.
To check if the battery is working, follow these steps:
- Press the button on the front of your Nest doorbell.
- If the device rings or lights up, your battery has some charge left.
- Open the Google Home app on your phone and tap on your doorbell.
- If the battery icon is low or empty, your doorbell needs charging.
- Remove your doorbell from its base plate using a release tool, paperclip, or thumbtack.
Nest Doorbell with Alternative Power Source
Alternative power sources include solar panels and power adapters.
- Plug the power adapter into an outdoor outlet and securely connect it to your doorbell.
- A green light on the adapter indicates it’s powering the doorbell.
#2: Charge or Replace the Batteries on Your Doorbell
If your Nest doorbell is connected to a power source but still shows no power, charge or replace the batteries. Here’s how to do this:
Battery-powered Nest Doorbell
If you have a battery-powered Nest doorbell, you must regularly charge its internal battery.
To do this, follow these steps:
- Remove your Nest doorbell from its base plate.
- Plug your doorbell into a power outlet using a USB-C cable.
- You should see a pulsating white light, which means your doorbell is charging.
- Wait until the light turns solid white, indicating the battery is fully charged.

- Press the button and see if it works.
Tip: A wired Nest doorbell has no replaceable batteries but an internal backup battery designed to last the doorbell’s lifetime.
#3: Inspect the Wiring for Damage or Loose Connections
Check the wiring for any damage or loose connections if your Nest doorbell is connected to a power source with enough battery but still shows no power.
To do this, follow these steps:
- Turn off the power to your doorbell at the breaker box for safety reasons.
- Remove your doorbell from its base plate.
- Check the wires behind your doorbell for damage, corrosion, or loose connections.
- Ensure they are securely attached to the terminals on your doorbell.
- Check the wires inside your chime box and ensure they’re secure.
- Repair or replace any damaged or loose wires.
Note: Verify that your existing wiring meets Nest doorbell compatibility requirements, including voltage and transformer compatibility.
#4: Power Cycle Your Doorbell via the Breaker
If you encounter a Nest doorbell with no power after a power outage, power cycle it via the breaker.
It will reset your device and clear any glitches that prevent it from working properly.
- Turn off the power to your Nest doorbell at the breaker box for safety reasons.
- Wait for about 10 seconds.
- Turn the power back on.
- Press the button and look at the light in front to see if your doorbell has power.
If your doorbell still has no power, move on to the next solution.
#5: Use an Alternate Power Source (Power Adapter or Solar Panels)
If none of the above troubleshooting methods work, you must use an alternative power source like a power adapter or solar panels.
These will help provide your doorbell with more reliable power.
Wired Nest Doorbell
- Buy a power adapter with a voltage rating of 18V AC and at least 0.5A current rating.
- Plug the power adapter into an indoor power outlet.
- Run the cable to your doorbell location.
- Cut off the wires connecting your doorbell to your system and transformer.
- Strip about half an inch of insulation from the ends of the wires.
- Twist together the matching wires from the power adapter and the doorbell.
- Secure the wires with wire nuts or electrical tape.
Battery-powered Nest Doorbell
- Buy solar panels with a voltage rating of 5V DC and at least 1A current rating.
- Install the solar panels in a sunny location near your doorbell.
- Run the cable from the solar panels to your doorbell location.
- Plug the cable into the USB-C port on the back of your doorbell.
- Look for a blue light on the solar panels, indicating they’re charging your doorbell.
Note: Once done, attach your doorbell to its base plate. Then, press the button on your doorbell and see if it works.
#6: Bypass the Chime
Bypassing the chime helps eliminate any interference or compatibility issues caused by it. Here are the steps to do this:
Wired Nest Doorbell
- Switch off the power at the breaker box.
- Open your chime box.
- Disconnect the wires labeled front, rear, or trans.
- Connect them to the corresponding terminals on your chime connector.

- Close your chime box and restore power to your doorbell.
If you have a battery-powered Nest doorbell, you don’t have to bypass the chime because it doesn’t have one.
Note: To hear your battery-powered Nest doorbell ring inside your home, get a compatible Google Nest speaker or display and pair it with your doorbell.

Here’s what you must do:
