Nest Doorbell Blinking Yellow? – (06 Easy Solutions)

Nest doorbell blinking yellow can be confusing to deal with.

When your device blinks in yellow, you won’t be able to use it at all until the issue is solved.

The yellow blinking is usually a code for issues related to the power, but in some cases, it can also be caused by a software issue. 

Whenever your Nest doorbell blinks yellow, check your power requirements and electrical wiring. Next, reset your doorbell and check your WiFi connection. Afterward, review the chime connector and test another device.

Why is My Nest Doorbell Blinking Yellow?

Nest Doorbell devices use blinking lights to signal different error codes or issues.

Depending on your device generation and model, you may see a pulsing circle or a small solid yellow dot blinking.

Yellow blinking is a code for irregular or too-weak power. 

Here is a list of the most typical causes for Nest doorbell yellow blinking:

• Power Adapter issues.
• Incorrect wiring .
• Transformer voltage problems.
• AC/Power source too weak.
• Software issues.

Now that we understand the underlying issues, we will attempt to troubleshoot!

How to Fix Nest Doorbell Blinking Yellow?

Tip: Complete all the steps below without skipping to get the best outcome.

1. Check Power Requirements

Google Nest doorbell blinking yellow can result from a mismatch in power requirements with the doorbell and your home grid.

Device compatibility also plays a significant role in proper operation.

For example, if the Nest system does not support your chime, your Nest doorbell might give a power issue or warning.

Here are some ways to ensure your power requirements are met:

• If your Nest Doorbell is plugged into a power socket, ensure you constantly use it with its provided power adapter. 
• Read up on your chime power requirements before integrating it with your Nest doorbell system. Ensure your setup has enough voltage to power all components.
• Ensure that your chime is wired adequately to your Nest Doorbell. If your chime does not have labeling on its wires, consider contacting a professional installer to help you.

Note: Some Nest Doorbells might require installing a transformer to integrate other devices, such as a chime.

2. Examine the Wiring

Bad wires that are either damaged or not conducting electricity properly can result in yellow blinking alerts from your Nest doorbell.

Your device can also suffer damage and malfunction when there is an issue with the wiring or they are misaligned and not connected correctly.

All your wires must be in good condition and adequately secured to ensure safe operation.

Here are some ways to ensure your wiring is working as intended:

• Stop the power to your home by turning it off from the circuit breaker. 
• Remove your Nest doorbell from its plastic holder.
• Take off the back plate to reveal the wiring.
• Inspect the slots where the cables come into contact with your doorbell.
• Ensure that any screws securing the wires are tight.
• If the copper on the wires is not exposed enough to conduct electricity, trim the plastic from the wire and install it again.

If your chime is on outside your home, ensure any exposed wires are insulated to prevent corrosion and short-circuiting from moisture or water buildup.

Note: If your Nest Doorbell is connected to a power adapter, try switching up the sockets to ensure it's not an issue with the power outlet.

3. Check the Voltage With a Multimeter

If you still have issues with a yellow blinking light, you must examine whether your wires provide enough power.

Depending on your current setup, you may or may not have additional devices, such as a power transformer for your doorbell system.

When you have a power transformer, checking if its connectors are in working order is an excellent idea.

To check your Nest doorbell and chime, you will need a multimeter to measure the voltage:

• Set your multimeter to measure AC or DC voltage from its settings (this can often be done by rotating a wheel to switch between modes).
• Connect the end of the probe to the endpoint of the exposed wires going to your Nest doorbell.
• Check for any signal – if you get no response on both cables, the wires must be replaced. 
• If live power goes through, ensure the voltage value is between the expected norms of 120 volts. 
• USA and Canada voltage standards state the current should be within +- 6% of the standard 120V target.

If your voltage is irregular, your setup might require the services of a professional electrician.

If the values you receive are not within norms, then this might cause damage to your devices, such as shorting their circuits.

Note: Always wear protective gear when handling live wires with the ongoing current.

4. Reset the Doorbell

Resetting your device can be an unexpected fix, as disconnecting a device from its power and waiting will clear any static electricity.

Having built-up electricity can trip up the sensors and cause a false power-related yellow blinking light.

Resetting the doorbell can also clear up software issues that might cause a false yellow blinking light alert.

Here is how to reset your Nest Doorbell if using a cableless setup:

• Remove the back panel and any batteries if you use a wireless Nest device. Then, wait for a minute and plug them back in. 
• Ensure that your batteries are not out of power, as this can cause issues with your device. Always use the original charger that came with your Nest to recharge batteries.

Here is how to reset your Nest doorbell if it’s connected to a power adapter:

• Unplug your doorbell from any power source or electrical socket.
• Wait for about 20 seconds, and then reconnect the Nest to the adapter and plug it back into a working socket.
• Wait for your doorbell to restart and see if the issue persists. 

Note: Keep a note of your device settings in case they get lost during this procedure.

5. Check the Chime Connector

The chime connector is a small device that connects to your chime and integrates it into your Nest doorbell system.

As there are many chime manufacturers, how they are configured might affect your Nest doorbell.

Here are some ways to ensure your chime connector is not at fault:

• Open your chime panel and see if the connector is not in contact with moving parts inside your chime.
• Using a chime connector from an older generation than your Nest doorbell won’t work as both are incompatible. 
• Second-generation devices only have two cables for power, while the old one has four. 
• If your chime connector is not compatible, consider upgrading it. 
• Check that the wiring from your chime connector to your chime is correctly installed. 

When in doubt about third-party chime manufacturers, it’s best to consult with their manual and look for installation guidelines.

Note: Scorching temperatures outside your house can cause your Nest doorbell system or chime to power off to prevent overheating. 

6. Hard Reset the Nest Doorbell

A hard reset will delete any user settings or configurations on your Nest doorbell, which can clear runtime software issues causing a yellow blinking light.

After resetting your device, it might appear offline in your Google Home app, so remove and re-add it.

Here is how to hard reset the Nest Doorbell:

1. Remove your doorbell from its plastic mount cover.
2. Take off your Nest doorbell back plate using a screwdriver if needed.
3. Look for a small pinhole, usually on the backside. Using a thin object such as a paperclip, press and hold the reset button.
4. Continue pressing the button until your Nest doorbell lights start flashing.

If the procedure has been successful, you will be prompted to pair your Nest doorbell again via the Google Home app.

Furthermore, after the reset, you must pair it to your home’s WiFi network.

Note: Hard resetting your Nest doorbell will eliminate any profile or user settings and delete stored data. Ensure to have all your info secured somewhere.

Quick Recap

To resolve the Nest doorbell blinking yellow, check all your wiring within your Nest doorbell configuration and ensure you meet all the power requirements.

Afterward, reset your doorbell and ensure your chime connector is installed correctly.

When in doubt about the electrical needs or setup, getting help from a licensed electrician is best.
