    I pinched the connector and it will not pull out

    I’m my case, the white backplate cannot be pulled until it is turned about 1cm counterclockwise to disengage the brackets that hold to the internal plate. To do this, yo need to hold the front of the Nest with the metal frame (so the it doesn’t turn), while turning the backplate.

    And in my case, there are only 2 screws (in the 9 and 3 o’clock positions) and not 4 as shown in the photo.

    Where do you buy the battery?

    Robert - Antwoord

    At least say the tipe of battery that's needed.

    Pedro Sanchez - Antwoord

    I just ordered the battery model specified. When it arrived, I realized it doesn’t have the same specs as the battery that comes with the thermostat.

    The part listed (TL284443) is 3.7 VDC, but it is only is 380mAh (1.41 Wh) (if you zoom in on the image when you click “Buy”, you can see)

    You can clearly see in the tear-down that the battery that comes with the thermostat is 2.1 Wh.

    It might work as a replacement, but doesn’t have the same capacity.

    Double check your own equip online or in the manual people.

    There are different generations of thermostats. How would this guy know which battery you need.

    Thanks for the directions.

    Helps a lot.

    LisaKK - Antwoord

    To be fair, most people don’t know that there are different generations of the Nest Thermostat and clearly they didn’t read that this was for the 2nd generation Nest Thermostat. Probably should have been pointed out in the instructions more clearly for those folks. Then they wouldn’t have been so confused about the battery voltage differences.

    I am a 64 year old woman, I had the Nest next generation installed last year. So far it keeps telling me that the connection to my wi-Fi is not working and now it’s saying the battery is dead. I’ve gone through all the steps to re-connect to wi-fi to no avail. Could this be because the battery needs replacing?

    It’s 68 degrees in my house now and that’s thanks to my fireplace not this horrible device. I am going back to the regular thermostat, what a waste of hard earned money.

    I can’t see how the LCD ribbon is reattached. Is it sliding just under the part that is pivoting up or is it beneath the wires below that?

Please could you say the type of LCD screen? Or present detailed photo of rear side?

vladvys - Antwoord

Yes, this is a guide for replacing the LCD. I'd like to know what LCD to order. Thanks.

kylegoetz - Antwoord

Thank you for providing this tutorial. My dog, not making this up, knocked my nest off the wall. Where can I purchase the replacement green itself and the plastic opening tools you used throughout the repair? This will be my first time on something like this, but with your guide I should have a decent shot at not screwing it up.

Skip step 12. There is no reason to remove the EMI shield.
