How to Fix Your Nest Thermostat When it Won't Respond

January 18, 2016
If your home is running on the Nest Thermostat you probably heard about the recent outages and may be living in fear of being left without heat in the dead of winter.

But fear no more!

Nest Support has published an informative page with the very convenient title “What to do if your Nest Thermostat has become slow, unresponsive, or won’t turn on.” Yes, that’s really the title.

For more detailed instructions, please visit their Nest Support page. For a quick overview, keep on reading:
Nest Thermostats that were updated at the end of 2015 or beginning of 2016 to software version 5.1.3 or later may have some issues, including becoming unresponsive, not effectively charging the battery, or shutting down completely. Nest says to try recharging and restarting your thermostat to rectify the glitch and get it up and working again.

Signs of this glitch include the following:
  • the thermostat not working in the Nest application and disconnected from the Wi-Fi
  • the thermostat notifies you that the battery is low and it needs to turn itself off
  • the thermostat’s animated properties are slower than usual
  • the thermostat shows a notification that says, “Please remove the thermostat from its base, then reattach it;”
  • the thermostat’s display won’t light up and unresponsive (you may also see a blinking red or green light above the display)
  • the thermostat can’t control the corresponding heating and cooling unit(s)

If your Nest Thermostat will turn on but you can’t control it or it’s running slow, try manually restarting it beginning with turning the thermostat off and then back on again. If your Nest Thermostat is off and won’t turn on, take the thermostat off the base and charge it using a USB cable plugged into a wall charger or a computer.

CAUTION: Do not try to restart your thermostat while it’s still connected to a computer for charging. (They didn’t elaborate why, but if Nest Support says don’t do it, DON’T.)

After around 10 minutes of charging, detach the Nest Thermostat from the USB cord. If the thermostat has turned on while charging, turn it off and then turn it back on again, manually restarting the system. Once it has restarted completely, plug it back in to reach full charge. After another 60 minutes of charging, detach the Nest Thermostat and reattach it to its base.

You should be ready to rock and this point, but again, for more detailed instructions and information, please go to Nest Support.
