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

If you have a Nest Thermostat you may have read 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 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, see their 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 correctly charging the battery, or turning off completely. Nest suggests recharging and restarting your thermostat to fix the problem and get it up and going again. 

Symptoms of this problem include the following: 

  • The thermostat not working in the Nest’s mobile app and disconnected from the Wi-Fi 
  • The thermostat alerts you that 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 dark 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 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 restart your thermostat while it’s still connected to a computer for charging. (They didn’t explain why, but if Nest says don’t do it, DON’T.) 

After around 10 minutes of charging, unplug the Nest Thermostat from the USB charger. If the thermostat has turned on while plugged in, power it off and then turn it back on again, manually restarting the thermostat. Once it has fully restarted, plug it back in to complete charging. After about 60 minutes of charging, unplug the Nest Thermostat and reconnect it to its base. 

You should be be ready to go at this point, but  if you’re done with Nest and want to swap your thermostat, you can see our comparison of common thermostats.
