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

If you purchased the Nest Thermostat you probably heard about the recent problems and may be living in fear of losing your home’s heating abilities 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.” Could you crack that code? 

For more detailed information, go to 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 have some issues, including becoming unresponsive, not effectively charging the battery, or going down completely. Nest recommends recharging and restarting your thermostat to resolve the problem and get it up and running again. 

Signs of this problem include the following: 

  • The thermostat being down on the Nest App and disconnected from Wi-Fi 
  • The thermostat tells you the battery is low and it needs to turn itself off 
  • The thermostat’s animated features 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 see 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 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 READ: 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, DON’T.) 

After roughly 10 minutes of charging, unplug the Nest Thermostat from the USB charger. If the thermostat has turned on while charging, power it off and then turn it back on again, manually restarting the system. Once it has completely restarted, plug it back in to reach full charge. After about 60 minutes of charging, disconnect the Nest Thermostat and restore it to its base. 

You should be good to go at this point, but  if you’ve had enough and want to swap your thermostat, you can view our comparison of common thermostats.
