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

January 18, 2016
If you purchased the Nest Thermostat you probably 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.” Could you crack that code?

For more detailed information, see Nest Support page. For a quick overview, keep on reading:
Nest Thermostats that were recently updated to software version 5.1.3 or later may be having problems, including becoming unresponsive, not effectively charging the battery, or going down completely. Nest recommends recharging and restarting your thermostat to fix the issue and get it up and going again.

Symptoms of this glitch include the following:
  • the thermostat being down on the Nest application and disconnected from the Wi-Fi
  • the thermostat alerts you that the battery is low and it needs to turn off
  • 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 dark and unresponsive (you may also have 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 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 a USB charger plugged into the wall or a computer.

IMPORTANT: 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, DO NOT DO IT.)

After roughly 10 minutes of charging, detach the Nest Thermostat from the USB cable. If the component has turned on during this time, power it off 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, unplug the Nest Thermostat and restore it to its base.

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