If you've already tried restarting the thermostat, the best thing to do is contact the Google Nest support team directly.
- Go to Contact Us - Google Nest Help
- Select an appropriate option, type a brief description of the issue, then click "Next".
- Click "Other", then click "Next step" until you see the contact options.
- Choose to get a call or call or chat with the team as available in your country.
Make sure you have the help code and your thermostat’s serial number ready to go before your call. To find your thermostat’s serial number, pull the display off the base and flip it over. The serial number is above the QR code on the back of the display. When you reach an agent, be sure to let them know you've already tried restarting your thermostat.
