Nest thermostat flashing, won't turn on

[KristyJaneB]

I have had issues before when turning on ''away'' and then coming back home and changing to ''home''. After a 3 week holiday I now cannot get my thermostat to turn on at all. Prior to this I was not able to access any menu options on the device. It has been continuously plugged in I have tried a full shutdown several times. I saw a previous thread that advised to plug it into a computer, I have tried on my mac and pc, when I plug it in I get a home screen, then just back to black. It's flashing mostly green but intermittently orange then red.

It is was only installed in January.

Hey KristyJaneB, 

Help is here — sorry for the delay but thanks for reaching out to the Google Nest Community. 

What type of Nest thermostat is this? How many minutes or hours had you left it plugged into a computer via USB cable? Also, was it only today that you've experienced this after it was installed last January?

Hello, Thanks for checking in.

The thermostat is faulty, it has been returned for a replacement.

Hi there, 

It's me again — have you had the chance to install the replacement thermostat? If yes, how is it?

The replacement was also faulty. I have received another one that I will try to set up today.

Hi there, 

Oh no, sorry about that. Hopefully, the 2nd replacement would work as it should.
