Why Is My Nest Thermostat Blinking Red? [ANSWERED]

You pass your Google Nest Thermostat on a daily basis and aren’t usually aware of anything unusual happening around it.

It simply sits there, day in and day out, carrying out its duties.

But then, one day, as you pass by, you notice a flashing red light on the street.

Is this a problem? If so, is it possible that the unit is experiencing some sort of random issue. What does that small red light that is blinking mean?

What Is the Purpose of My Nest Thermostat Blinking Red? [ANSWERED]

If your Google Nest Thermostat begins to blink red, it means that its battery is running low. This, of course, means that you will need to replace the battery before the current one has completely depleted its charge capacity.

Lastly, yes, the red light signifies the same thing regardless of which Google Nest Thermostat model you are currently using in your residence.

First and foremost, don’t get too worked up. It isn’t necessarily a negative development.

Depending on its requirements, the Nest Thermostat will blink different coloured LEDs.

It will occasionally flash red when it is turned on. At other times, it may flash a green light.

Additionally, it could begin to blink orange or white at some point in the future.

Each of these colours represents a different emotion.

They are essentially the thermostat’s way of informing you of what it requires of you in order to function properly.

You might be a little perplexed if you notice the thermostat’s red light blinking.

Given its position as one of the most widely used smart thermostats on the market right now, you would expect the Google Nest Thermostat to operate with relative ease.

And it will, for the most part, succeed. When your thermostat starts blinking red at you without giving you any apparent warning, it can be extremely frustrating.

What exactly does it mean? When do you think you should deal with this problem?

When something like this happened to me and my thermostat, I had these thoughts running through my head.

It wasn’t until I went online and did a little bit of research that I discovered that my panicked thoughts could be quickly and easily calmed.

Allow me to share what I’ve learned about what a red blinking light on the Nest Thermostat means in more detail.

What does it mean when the Google Nest Thermostat’s lights start blinking?

If you notice any blinking lights on your Google Nest Thermostat, you should know that each one has a different colour.

Because it can blink in several different colours, we will go over each of them, including the red blinking light that is currently plaguing your existence.

When the red blinking light on the Nest Thermostat appears, what does it mean?

What do the lights on the Nest signify? First and foremost, it is important to note that the colour codes are consistent across all Nest models and generations.

What is the significance of the red light on my Google Nest? This one is simple: it simply indicates that the thermostat’s battery is nearing the end of its life.

It hasn’t died yet, but it will be dead in a short period of time.

Other possibilities include a blank screen or the home symbol appearing on the screen.

Upon completion of the battery charge, the red blinking light will cease to function.

It may take anywhere from 10 minutes to an hour for the thermostat to restart itself after it has finished charging.

If your Nest battery is not charging, you will need to locate the device’s USB port and connect a USB cable directly into the thermostat to ensure that it is charging properly.

What happens if the Nest Thermostat begins to blink green?

The presence of a blinking green light on your Nest Thermostat simply indicates that it is in the process of updating its firmware.

Google releases updates on a regular basis, and when this occurs, the light blinks green to indicate that an update is being installed or that the computer is restarting after an update.

Hopefully, this will only take a few minutes, and then the light will stop blinking altogether.

If the thermostat displays a steady green light, this indicates that it has become stuck during a software update.

If this occurs, you will need to remove the thermostat screen from the base and secure it in place, which is indicated by a click on the thermostat screen.

If this method does not work to restart the thermostat, you will need to press down on the display for 10 seconds before releasing the button. This should resolve the situation.

Was there a reason for the orange light to be on?

A blinking orange light can be a little perplexing at first.

You should remove the thermostat’s screen from its base and connect a USB cord to the thermostat’s port, allowing the thermostat to charge while you are doing so.

After that, you should receive a message instructing you to reconnect the screen to the base.

To do so, carefully press down on the display until you hear a click as it locks into place.

What does it mean if there is a white light that is blinking?

If you’ve had to perform a manual reset, you’ll see a white blinking light appear. In addition, this can occur when the thermostat is reconnecting to the WIFI router or after an update is performed.

If you see this and it doesn’t stop, check to see that the display is properly mounted to the base and that the internal wires and connectors are properly connected together on the motherboard.

You can also try restarting your thermostat if that doesn’t fix the problem.

A blank screen on the Nest Thermostat indicates what is happening.

When the screen goes blank, it means that the battery has been completely depleted.

It could also indicate that a connection is loose somewhere, that wiring is damaged, or that a fuse is blown.

To check for any of these issues, press the ON button on the thermostat to ensure that it has not been accidentally turned off.

You will then need to inspect the wiring and fuses for any potential damage and, if you discover any, you will need to contact a professional to assist you with the repairs.

Lastly, some final thoughts

A blinking red light on your Google Nest Thermostat is nothing to be concerned about, but it does indicate that you will need to recharge the battery before it completely drains and leaves you with a blank screen on your Google Home device.

This is normal behaviour for the thermostat in this environment.

However, if the issue is extremely persistent, you may be dealing with a more serious problem, such as a faulty battery, which will need to be addressed in order for your Google Nest Thermostat to function as intended.
