Nest six wire model

[Dollyhall00]

My older nest thermostat is completely blank. I can’t get it to restart.

Hey Dollyhall00,

I’m sorry to hear you’re having trouble with this. No worries, we'll check this out. What type of Nest thermostat do you have? You can charge your Nest thermostat with a USB cable. Follow the steps below and let us know how it goes.

1. Pull off the thermostat display and use the USB port on the back to charge it with a USB cable and wall charger. Depending on the model that you have, it'll be either a mini or micro USB.
   Note: Do not use a computer USB port or other unpowered USB port for charging.
2. The display should eventually light up with a message asking you to connect it to the base. Reconnect the display to the thermostat base. Press firmly until you hear it click into place.
3. You can continue to install or use your Nest thermostat, but if you haven't fixed the underlying problem then your thermostat will lose power again. Continue with the steps below if that happens.

Thanks,

Archie
