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

January 18, 2016
If your home has the Nest Thermostat you probably read about the recent problems and may be living in fear of being left without heat in the dead of winter.

But fear not!

Nest Support has published a page with step by step instructions 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 more basic 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 efficiently charging the battery, or going down completely. Nest suggests recharging and restarting your thermostat to rectify the glitch and get it up and going again.

Indications of this problem include the following:
  • the thermostat being offline in the Nest’s mobile app and disconnected from the Wi-Fi
  • the thermostat tells you the battery is low and it needs to turn itself off
  • the thermostat’s animated properties 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 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 system(s)

If your Nest Thermostat is turned on but you can’t control it or it’s performing 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 cord 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, LISTEN TO THEM.)

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

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