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.

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.

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.
