Your Nest Thermostat is blinking green and orange this is due to an interior error. This could be anything from your battery needing to be charged, or not holding a charge.
It could be a bug/glitch within the Nest Thermostat software that is causing this error to appear. It could even be a faulty thermostat due to basic wear and tear.
Below I will be going over the most common reasons why you are seeing your Nest Thermostat blinking green and orange.
Why is Nest Thermostat Blinking Green and Orange?
1. Issue With Nest Thermostat Fan
Seeing your Nest Thermostat blinking green and orange is mostly due to an issue with your fan. This issue can be caused by the lack of power to your Nest Thermostat and your fan can not work properly.
You may have noticed that along with the blinking orange and green light, that your fan is acting differently. The fan could suddenly speed up, or it could suddenly turn off completely and power back on.
This is not a normal action that your Nest Thermostat fan should be doing. And since the reason behind this is the lack of power to your Nest Thermostat that is causing the fan to malfunction, there is an easy solution to solve this problem.
Fix – Charge Nest Thermostat Battery
The best thing you can do when your Nest Thermostat is blinking orange and green is to charge the battery on your Nest Thermostat.
The reason why you are seeing blinking orange and green light on your Nest Thermostat is a fan issue, and if your Nest Thermostat has low power this can cause your thermostat’s fan to malfunction.
Recharge your Nest Thermostat by pulling the display off the box, and use the correct USB cord to plug it in to charge. It is recommended that you charge it for at least two hours to make sure it is full charge.
When your Nest Thermostat is fully charged this should stop the light from blinking and should get your thermostat running properly.
2. Bug/Glitch Within Nest Thermostat Software
Another common reason why you are seeing the orange and green lights blink on your Nest Thermostat could be a bug/glitch within the software.
Like with all devices when there is a bug/glitch within the software this could cause some features on your Nest Thermostat from functioning properly.
One of these features could be the thermostat fan which is why you are seeing the blinking orange and green lights. This can be solved by checking and performing a software update on your Nest Thermostat.
Fix – Update Nest Thermostat Software
Is there a bug/glitch within the software of your Nest Thermostat that is causing your thermostat to blink orange and green? Like all devices bugs/glitches can appear from time to time and that is when updates come in handy.
Updating your software on any device can clear any bugs/glitches that may be present within the software. Having corrupt files within the software of your Nest Thermostat can cause it to not function properly.
If you do not know how to check for any updates on your Nest Thermostat then follow the steps below.
- On the home screen of your Nest Thermostat select the Settings option.
- Depending on what model of Nest Thermostat you have, the next option will either be labeled as Software or Version, select that option.
- Next you will see an Update option, select that to do an update on your Nest Thermostat.
3. Issues With Nest Thermostat Wires
One thing to also consider when seeing your Nest Thermostat blinking green and orange is that the reason behind that could be an issue with the wires. There could be a loose wire that is causing your thermostat to not be at full power.
Since the green and orange light usually means an issue with your thermostat not having enough power, causing features to not properly work.
If you have loose wire or even damaged wire this can cause loss of power to your Nest Thermostat. This can even cause more severe issues with your thermostat depending on what wire is loose or damaged.
Fix – Check if Wires Are Connected Properly
Checking the wires on your Nest Thermostat can be difficult, especially if you do not know much about the wiring system of the thermostat. You can look over some of the wires when you take off the thermostat display.
If you do notice that some wires are either damaged or loose it is advised that you do not attempt to fix this yourself. You should contact the Customer Support Team to see what they advise you to do next.
Most likely you will be advised to call a professional to repair or replace the wires on your Nest Thermostat.
4. Nest Thermostat Can Not Hold a Charge
As mentioned above the main reason behind why you are seeing blinking orange and green lights is due to an issue with the power supply.
The first fix is making sure your Nest Thermostat is fully charged, but what happens when your thermostat can not hold a full charge?
That is a possibility and if your Nest Thermostat can not hold a full charge then this can cause features on your thermostat to not work correctly.
If you have the Google Nest App downloaded on your mobile device you can check the power reading on your thermostat. This can tell you if your Nest Thermostat is having issues with holding a full charge.
Fix – Check Power Supply On Nest Thermostat/Contact Customer Support
When your Nest Thermostat is not holding a full charge this can cause features on your thermostat to not properly function. Since your thermostat is lacking the proper power supply feature like the fan will malfunction and not act normally.
If you have the Google Nest App downloaded on your phone you can go into the Settings, and under the Technical Info option, you will see Power. Select the Power option and you will see the power reading on your Nest Thermostat.
Check this while you are charging the thermostat and see if it is holding a charge. If your Nest Thermostat is not holding a charge this could be an issue with the battery or hardware.
The best thing you can do at this point is to contact the Customer Support Team and get their opinion on what should be your next course of action.
5. Faulty Nest Thermostat
When you have tried all the options above and you are still seeing the blinking orange and green light on your Nest Thermostat and certain features are not working correctly. Then this issue could be due to a faulty Thermostat.
Like all devices faulty hardware can be possible, either due to wear and tear over time, or it could even be a manufacturer problem.
Whatever the reason is if your Nest Thermostat is faulty there is not much you can do on your side. This is an issue left for the professional or just getting your Nest Thermostat replaced with a new one.
Replace Nest Thermostat Or Contact Support
If you’re still having issues with your Nest thermostat, it’s time to either replace your Nest Thermostat.
I personally use the Nest Learning Thermostat, which I picked up from Amazon.
Note: Only pick up a new Nest Thermostat if you’re convinced the one you currently have has too many issues. There’s no point in picking up a new thermostat if the problem with your current thermostat can easily be fixed.
