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

January 18, 2016
If you purchased the Nest Thermostat you may have read about the recent problems and may be living in fear of the dreaded technology glitch that is causing many Nest users to lose heat in the dead of winter.

But fear not!

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.” Obvious, much?

For more detailed instructions, please visit their Nest Support page. For a more basic 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 have been having some problems, including becoming unresponsive, not correctly charging the battery, or shutting down completely. Nest says to try recharging and restarting your thermostat to resolve the glitch and get it up and going again.

Signs of this problem include the following:
  • the thermostat being down on the Nest’s mobile app and disconnected from the Wi-Fi
  • the thermostat tells you the battery is low and it needs to shut itself down
  • the thermostat’s animated properties are slower than usual
  • the thermostat shows a message saying, “Please remove the thermostat from its base, then reattach it;”
  • the thermostat’s display is black and unresponsive (you may also see a blinking red or green light above the display)
  • the thermostat can’t control the corresponding HVAC unit(s)

If your Nest Thermostat is turned on but you can’t control it or it’s performing slow, try manually restarting it and turn 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 cord plugged into a wall charger or a computer.

CAUTION: Do not try to manually 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, disconnect the Nest Thermostat from the USB cable. If the thermostat has turned on while charging, shut it down and then turn it back on again, manually restarting the thermostat. Once it has fully restarted, plug it back in to complete charging. After about 60 minutes of charging, unhook the Nest Thermostat and reattach it to its base.

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