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

January 18, 2016
If your home has the Nest Thermostat you may have heard 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 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, please visit their Nest Support page. For a quick summary, 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 correctly charging the battery, or turning off completely. Nest suggests recharging and restarting your thermostat to rectify the problem and get it up and running again.

Symptoms of this problem include the following:
  • the thermostat being offline in the Nest App and disconnected from Wi-Fi
  • the thermostat tells you the battery is low and it needs to turn 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 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 running slow, try manually restarting it beginning with 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.

CAUTION: Do not try to power on or off your thermostat while it’s still connected to a computer for charging. (They didn’t go into detail why, but if Nest says don’t do it, DON’T.)

After approximately 10 minutes of charging, disconnect the Nest Thermostat from the USB cord. If the component has turned on while charging, power it off and then turn it back on again, manually restarting the system. Once it has fully restarted, plug it back in to fully charge. After another hour of charging, detach the Nest Thermostat and reconnect it to its base.

You should be be ready to go and this point, but again, for more elaborate instructions and information, see Nest Support.
