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

If your home is running on the Nest Thermostat you may have 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 informative page with the very convenient title “What to do if your Nest Thermostat has become slow, unresponsive, or won’t turn on.” Obvious, much? 

For complete instructions, see 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 may be having problems, including becoming unresponsive, not effectively charging the battery, or turning off completely. Nest recommends recharging and restarting your thermostat to rectify the glitch and get it up and running again. 

Symptoms of this problem include the following: 

  • The thermostat being down on the Nest application 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 a message saying, “Please remove the thermostat from its base, then reattach it;” 
  • The thermostat’s display is black 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 unit(s) 

If your Nest Thermostat will turn on but you can’t control it or it’s acting sluggish, 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 USB cable plugged into a wall charger or a computer. 

ATTENTION: 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 says don’t do it, LISTEN TO THEM.) 

After approximately 10 minutes of charging, disconnect the Nest Thermostat from the USB cable. If the unit has turned on during this time, shut it down and then turn it back on again, manually restarting the system. Once it has completed the restart, plug it back in to fully charge. After an hour of charging, unhook the Nest Thermostat and restore it to its base. 

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