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 problems and may be living in fear of losing your home’s heating abilities 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, go to their Nest Support page. For a quick summary, keep on reading:
Nest Thermostats that were recently updated to software version 5.1.3 or later have been having some problems, including becoming unresponsive, not effectively charging the battery, or shutting down completely. Nest says to try recharging and restarting your thermostat to rectify the issue and get it up and going again.

Symptoms of this problem include the following:
  • the thermostat being down on the Nest’s mobile app and disconnected from the Wi-Fi
  • the thermostat notifies you that the battery is low and it needs to shut itself down
  • the thermostat’s animated features 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 dark and unresponsive (you may also observe a blinking red or green light above the display)
  • the thermostat can’t control the corresponding HVAC system(s)

If your Nest Thermostat is on but you can’t control it or it’s 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 cable 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 explain why, but if they say don’t do it, DO NOT DO IT.)

After about 10 minutes of charging, unplug the Nest Thermostat from the USB cord. If the unit has turned on while charging, shut it down and then turn it back on again, manually restarting the Nest. Once it has completely restarted, plug it back in to finish charging. After an hour of charging, disconnect the Nest Thermostat and reconnect it to its base.

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