Your Nest thermostat blinking green and you don’t know how to fix it? Today we are going to provide you with transparency and your inquiry with our ultimate fixing guide.
You will learn how other people managed to get the same issue resolved and how you can too!
If the green light on top of your Nest thermostat is continuously blinking, it means that your device is having an update.
It could also indicate system startup, shut down, and restart on some occasions. After a power outage, for instance, the light will blink for a few seconds until your Nest is working again.
These were the most common reasons for your Nest light blinking, and next, we will take a look at possibilities in which blinking could mean something bad.
In most cases, a green light blinking for around 1 minute will indicate system action. We’ve mentioned above that system actions could be restart and start-up or shut down.
But a crucial part is that sometimes there could be a hardware malfunction which could also make the light blink green.
To illustrate all of the occasions better, we’ve made a list of possibilities at your disposal:
- System update – Your Nest device is currently updating its firmware.
- System startup/shut down – Your device is either turning on or off.
- System failure – Your device can’t turn on so the light will keep blinking in green.
- Power failure – The light on your Nest will blink in green for several minutes after a power outage.
- Software Issue – Severe glitch or bug preventing your Nest from working properly.
- Hardware Issue – Something went wrong with the Nest hardware.
Keep in mind that if the light is blinking in green for around a minute and then your device starts up, there is nothing to worry about.
Continuous blinking is the thing you should be aware of because this will indicate some kind of failure in your Nest device.
Now when you have a basic idea of where the issue could be coming from, it is time to proceed with our solutions.
Again, it is important to remember that our solutions are designed to resolve issues when the green light is continuously blinking.
In case you’ve noticed the issue a moment ago, wait for at least 5 minutes to ensure that the light won’t stop blinking.
The most common approach that anyone would recommend to you right off the bat is to perform simple maintenance. By maintenance, we mean restart, power reset, and a new flow of electricity for your device.
For more details on how to perform a power cycle, follow the steps we have provided you with down below.
- Turn off your Nest thermostat device and wait for several minutes.
- Unplug all of its cables including the one supplying your device with power.
- Wait for another 15 minutes of your Nest being unplugged.
- Plug all cables back in by connecting the power one first.
- You are all done!
Important: Interacting with your Nest thermostat while it is free of electricity is of importance.
Unplugging cables and disassembling parts of the device might represent a threat if there is an active power flow within your Nest.
We would also recommend you plug your Nest into a wall outlet if you are using a divider or strip. This way you will determine whether there is a malfunction with your strip/divider or not.
If your Nest has been blinking for more than 15 minutes now, reconnecting the display of your device might help your situation.
The steps down below will get you more familiar with how to reconnect your display safely:
- Turn off your Nest to avoid possible injury or short circuit.
- Wait for at least 15 minutes for your device to cool off.
- Pull the display straight off the base.
- Ensure that the pin connector is perfectly lined up and push it back onto the base.
- An audible click should identify successful display placement.
This is how to reconnect your Nest thermostat display without exposing yourself to any kind of injury.
Turning your device off is of great importance, so make sure to always keep it off while interacting with it.
If display reconnecting didn’t work, a restart of your Nest thermostat might be able to fix the green light blinking.
You can check the steps down below to ensure a proper thermostat restart:
- Make sure that your Thermostat is working.
- Press down the display of your Nest thermostat.
- Hold this position for up to 10 seconds.
- Release the display and let your device restart.
Important: If the green light hasn’t been blinking by now, it will immediately start flashing because your device is performing a restart.
Don’t get discouraged, because this is how it works.
As we’ve briefly mentioned above, Nest blinking green light could also indicate a firmware update.
If that update is bigger than other ones you’ve already applied to your device, the green light might blink for more than half an hour or so.
Make sure to check the Nest app on your phone to see how your device is doing and whether there are updates or not.
Tip: You can install the Nest app from Google Play or App Store depending on your OS. To pair the app with your Nest, you would simply have to scan its signal via Bluetooth.
The last possible problem that we’re left with that might keep the green light on your Nest on, is a hardware failure of your device.
Even if the green light is not meant to indicate a hardware failure, if something happens with your device and it cannot turn on/off, the green light will blink.
Before taking any actions on your own, we highly recommend reaching out to Nest customer service to speak with a skilled technician that might have the solution for you.
In the worst-case scenario, you will be having a faulty hardware piece where you would need to spend some money on a repair.
If your warranty is still intact, you can deliver the device for repair at your manufacturer’s headquarters.
Now that you know why is Nest thermostat blinking green, you can perform the troubleshooting more efficiently than before.
Applying the methods with care is of great importance, so make sure that you don’t skip any step.
