Wire-free installations
Use these instructions if your doorbell runs only on battery power and isn't connected to wires or a plug-in power adaptor.
1. Check the battery charge
The app sends multiple notifications to let you know that your doorbell's battery charge is low and that you should charge it. If you didn't have a chance to charge it before the battery got too low, simply take it off the back plate and charge it with the included USB-C cable.
2. Check chime settings in the app
Your current settings may prevent the chime from ringing. For example, someone who shares access to your Nest home may have turned the chime off or changed the chime duration in the app.
Home app
- Open the Google Home app.
- Tap and hold your device's tile.
- Tap More
Quiet time, then tap Cancel if it's active.
3. Check the Wi-Fi connection
Check that your doorbell isn't listed as offline in the app. If it is, use the articles linked below to troubleshoot.
- Get Nest Doorbell visitor announcements on a speaker or display
- Troubleshoot Wi-Fi and connection issues
Wireless doorbell installations typically use a Google or a compatible speaker or display to sound the chime. Make sure that the device that you use for the chime is connected to Wi-Fi and correctly set up in the app.
4. Extremely hot weather
If it's extremely hot outside, or if your doorbell is installed in direct sunlight, the chime (and video or Wi-Fi) may turn off automatically to help protect its internal circuitry. The chime automatically turns on again when your doorbell's internal temperature returns to its normal operating range.
As long as your doorbell isn't disconnected from Wi-Fi and offline in the app, you can still get a notification on your phone when someone rings the doorbell.
Wired installations
1. Check the circuit breaker or power socket
- Make sure that the fuse or circuit breaker switch that supplies power to your doorbell is on.
- If you have the Indoor Power Adapter (available in the US only), check that the socket receives power by plugging in another electronic device like a lamp.
- Plug the power adaptor into another socket that you know is working. If the adaptor doesn't work, you'll need to replace it.
- If the socket is controlled by a switch, make sure that it's set to on as well.
2. Check chime settings in the app
Your current settings may prevent the chime from ringing. For example:
- Someone who shares access to your Nest home with the app may have turned the chime off, or changed the chime duration.
- If you have a mechanical chime (moving parts that make the sound), the chime duration option should be turned off. This setting is for electronic or digital chimes only.
Home app
- Open the Google Home app.
- Tap and hold your device's tile.
- Tap More
Nest app
- Open the Nest app.
- Select your doorbell.
- Tap Settings
- If quiet time is on, tap it to reveal the switch. Tap the switch to turn it off.
- Next, check the chime duration. Tap Chime duration in the settings menu.
- If you have a mechanical chime with moving parts that ring the bell, this option should be set to Off.
- If you have a digital chime (with internal speaker and no moving parts), and the chime duration is set too short, the chime may not make any sound or only make part of the chime sound. Try to set it to a longer duration.
3. Check the chime wires
Mechanical chimes
If you have a mechanical chime that has moving parts to make the 'ding dong' sound, the connector may interfere with the movement of the striker or the sounding bar that the striker hits.
First, test with the chime cover off:
- Remove your chime's cover.
- To ring the chime, press your doorbell's button.
If the chime sounds good with the cover off, the cover may be pressing on some wires or the connector and interfering with the moving parts.
- Bend the wires or use some tape to hold them out of the way.
- Re-test with the cover on.
- If it still sounds bad, mount the connector outside your chime box with some double-sided tape.
- Re-test with the cover on.
If the chime sounds bad or doesn't sound with the cover off:
- Get someone else to press the doorbell button while you look at the chime. You might notice something that interferes with the movement.
- Bend the wires or use some tape to hold them out of the way if needed. You can also mount the connector outside your chime box with some double-sided tape.
- Re-test with the cover off.
- If the cover-off test sounded good, retest with the cover on to make sure that nothing moved when you put the chime cover back on.
- Double-check that the wires are fully inserted into the chime connector and have a solid connection to your chime. Retighten any screws that hold wires with a screwdriver.
- Corrosion and grime can affect the wire contact. Check each wire end to make sure that they're all clean and aren't corroded. If not, trim off the corroded end and strip the casing to expose fresh wire.
- Make sure that any exposed wires, where the bare metal shows, don't touch each other.
- Make sure that you've installed the wires correctly according to the app instructions.
Electronic or digital chimes
If you have an electronic or digital chime that doesn't have moving parts.
Make sure that the connector is properly installed:
- Double-check that the wires are fully inserted into the chime connector and have a solid connection to your chime. Retighten any screws that hold wires with a screwdriver.
- Make sure that any exposed wires, where the bare metal shows, don't touch each other.
- Make sure that you've installed the wires correctly according to the app instructions.
- If your chime has more than three wires, you should contact a Nest Pro for installation help.
4. Check the doorbell wires
It's possible that a wire came loose when you put your doorbell on the back plate, or that the wires aren't tight enough. Make sure that the wires are securely connected.
- Remove your doorbell from the back plate.
- Retighten the screws that hold the wires with a screwdriver.
- Make sure that the ends of the wires don't touch each other or the base plate. Trim the wire ends and bend them if needed.
- To test the chime, press the doorbell's button.
5. Check the battery charge on Nest Doorbell (battery)
Nest Doorbell (battery) always runs off battery power, even if you've connected it to another power source. The power source uses low voltage to gradually charge the battery.
- The battery won't charge at temperatures below 0°C (32°F). In cold weather, bring the battery indoors and charge it with the included charging cable.
- The doorbell's settings can affect battery life. Change the settings to help save the battery.
6. Check transformer compatibility
Your transformer needs to meet specific power requirements to be compatible. If you're not sure about your transformer's power rating, you can contact a Nest Pro installer or an electrician or follow the instructions in the following article:
How to check your transformer's voltage
Important: Some doorbell systems may not be able to deliver enough power to the chime after Nest Doorbell installation, even if the transformer is rated between 8 to 24 V AC and 10 VA in North America or 8 to 24 V AC and 10 VA in Europe. If you have completed the other troubleshooting steps in this article, your transformer may need to be upgraded or replaced. You can have a local Nest Pro do it for you.
7. Extremely hot weather
If it's extremely hot outside, or if your doorbell is installed in direct sunlight, the chime (and video or Wi-Fi) may turn off automatically to help protect the doorbell's internal circuitry from excessive heat. The chime automatically turns on again when your doorbell's internal temperature returns to normal operating range.
As long as the doorbell isn't disconnected from Wi-Fi and offline in the app, you can still get a notification on your phone when someone rings the doorbell.
