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

January 18, 2016
If you have a 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.

We are here to calm your fears!

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 complete instructions, see Nest Support page. For a quick overview, keep on reading:
Nest Thermostats that were updated recently 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 fix the problem and get it up and working again.

Signs of this issue include the following:
  • the thermostat being offline in 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 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 won’t light up and unresponsive (you may also observe a blinking red or green light above the display)
  • the thermostat can’t control the corresponding HVAC unit(s)

If your Nest Thermostat will turn on but you can’t control it or it’s running 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.

ATTENTION: Do not try to power on or off 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, LISTEN TO THEM.)

After approximately 10 minutes of charging, detach the Nest Thermostat from the USB cord. If the component has turned on while charging, turn it off and then turn it back on again, manually restarting the thermostat. Once it has fully restarted, plug it back in to fully charge. After another hour of charging, detach the Nest Thermostat and restore it to its base.

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