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

January 18, 2016
If you have a Nest Thermostat you probably read about the recent outages 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 no more!

Nest Support has published an instructional 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 their Nest Support page. For a more basic summary, keep on reading:
Nest Thermostats that were updated recently to software version 5.1.3 or later may have some problems, including becoming unresponsive, not correctly charging the battery, or turning off completely. Nest suggests recharging and restarting your thermostat to resolve the glitch and get it up and going again.

Signs of this glitch 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 turn off
  • the thermostat’s animations are slower than usual
  • the thermostat shows an alert 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 observe a blinking red or green light above the display)
  • the thermostat can’t control the corresponding heating and cooling system(s)

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

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

After roughly 10 minutes of charging, detach the Nest Thermostat from the USB charger. If the component has turned on while charging, power it off and then turn it back on again, manually restarting the thermostat. Once it has completed the restart, plug it back in to complete charging. After about 60 minutes of charging, disconnect the Nest Thermostat and reattach it to its base.

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