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

If your home is running on the Nest Thermostat you have probably read about the recent issues 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. 

We are here to calm your fears! 

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 more detailed information, please visit Nest Support page. For a more basic overview, keep on reading: 

Nest Thermostats that were updated at the end of 2015 or beginning of 2016 to software version 5.1.3 or later have been having some problems, including becoming unresponsive, not effectively charging the battery, or going down completely. Nest recommends 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 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 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 dark and unresponsive (you may also have 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 cable plugged into a wall charger or a computer. 

PLEASE READ: 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, LISTEN TO THEM.) 

After around 10 minutes of charging, unplug the Nest Thermostat from the USB charger. If the component has turned on while plugged in, 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 about 60 minutes of charging, disconnect the Nest Thermostat and reattach it to its base. 

You should be good to go at this point, but  you can’t get it to work and want to swap your thermostat, you can view our comparison of common thermostats.
