Nest Doorbell Green Light on But Not Working: Causes and Solutions

Here are the most potential reasons why this kind of trouble may appear with your Nest doorbell and their possible solutions:

1. Wi-Fi Connection or Offline Issue:

If there’s an issue with the Wi-Fi connection or router, it can also lead your Doorbell to become frozen while the connectivity status may still indicate it’s in operating mode.

It could be due to the unstable internet, distance, interference (physical or Wireless) in between the devices, or incompatible bandwidth configuration.

You may also experience a situation where your Doorbell is offline when it blinks a green light, but after about 10 seconds the light goes off and comes right back. Besides connection issues, this can indicate a problem with the power source too.

Fix:

• Check your Wi-Fi connection. Make sure that your Wi-Fi network is working properly, and you can even use another device to the same Wi-Fi modem or router to verify that your router has no issue.
• Ensure that the Nest doorbell is within range of the wireless router and your router has a 2.4 GHz bandwidth configuration instead of 5 GHz.
• Confirm there are no physical or Wireless obstructions to cause poor signal between your Doorbell and router.
• Don’t let too many devices use the same internet connection and turn the devices off which are not needed at the moment.
• Restart or reboot your router to refresh and boost the connection.
• Check for any software updates Google Home app and ensure that your Nest doorbell is running the latest software version.
• Perform a factory reset on your Nest doorbell. Note that this reset will erase all the settings and data on the device.

If these steps do not resolve the issue, contact Nest support for further assistance.

2. The Transformer Isn’t Compatible with Your Doorbell and It’s Not Getting Enough Power:

If you do not have the correct type of transformer, your Doorbell won’t get enough power, and this may lead you to encounter similar trouble.

If you have an incompatible transformer that doesn’t meet the power and voltage requirements recommended by Google Nest, your doorbell will fail to function properly or may turn unresponsive too.

This kind of issue arises especially when customers upgrade to the Gen 2 Nest devices from Gen 1.

The power issue may also arise when there’s a power outage in your area which causes your devices to restart abruptly. This may cause your Nest to have a reconnecting failure with the Wi-Fi source device and Google Home.

Fix:

In that case, test the voltage range of the current transformer, visit the How to Check the Nest Doorbell’s Transformer Power and Voltage requirements, and follow the step-by-step instructions. If the current want doesn’t meet the standard, replace the transformer.

However, keep in mind that this troubleshooting work will need a certain amount of skill. So, if you’re not confident enough, consult and hire a local Nest Pro.

3. Your Doorbell Needs to Be Factory Reset:

In some cases, Nest (Wired) Doorbells may suddenly stop functioning or go offline even though the Greenlight keeps blinking

• when there’s any kind of change in the setup or connection, such as if you have readjusted, changed the password, or reformatted the router.

You may notice that after you turn the Wi-Fi router back on like normal, your doorbell hasn’t turned On and you can’t reconnect it or add it as a new one.

These are the signs that your Nest doorbell needs a factory reset and you need to reconnect the doorbell to your Google Home as new afterward.

Fix:

You should follow the earlier explained steps to perform the factory reset, but if that does not work, try the following:

• Check that the wires are firmly linked to the doorbell.
• Disconnect the doorbell’s wires. Then, use the provided USB cord to connect your camera to your computer/laptop’s USB port.
• When you see the status light pulsing blue, wait a few minutes before reconnecting it to the Wi-Fi. It means that your doorbell is operating
• Attach the doorbell to the wall plate and ensure the wires are securely in place.

4. Doorbell Wasn’t Installed Correctly or Has Improper Wiring:

This sudden commotion can be a result of one of the following:

• Maybe there was a system error (Wi-Fi connection or power outage issue during the process),
• You have mistakenly messed up during your doorbell setup process which must be causing the issue.
• Maybe you could not install the Wired doorbell correctly and didn’t tighten the screws enough to keep the wires in place.
• Wires may also wear out or come loose over time and cause trouble.

Fix:

Make sure you have installed the Doorbell correctly.

Verify that there’s no Wiring issue by checking these:

5. Doorbell May Be Still Connected to Its Previous Owner’s Device:

If you purchased a pre-installed (or used) Nest doorbell or if the doorbell was already set up in your home where you just moved in, most probably the doorbell is still connected with the previous owner’s Google Home or Nest device, and s/he didn’t remove the doorbell from the “Device List” yet.

Fix:

Until the previous owner removes the doorbell, you cannot pair your account or devices with the doorbell. So, the only solution is to contact the previous owner and ask them to disconnect it.

If that’s not possible for you, immediately consult with Google Nest Help Centre for further assistance.

6. Technical or Software Upgrade Related Issue:

Most customers get this issue solved after either Factory Resetting the Doorbell, re-adjusting the Wiring, or changing the Transformer.

But in rare situations, this problem can arise because of technical issues caused due to a software upgrade from the Google end.

Fix:

In that case, the only solution for you is to contact Nest Pro for professional help.
