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

January 18, 2016
If your home has the Nest Thermostat you probably heard about the recent issues and may be living in fear of being left without 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.” Could you crack that code?

For complete instructions, see their Nest Support page. For a quick summary, keep on reading:
Nest Thermostats that were updated recently to software version 5.1.3 or later may be having problems, including becoming unresponsive, not effectively charging the battery, or shutting down completely. Nest suggests recharging and restarting your thermostat to resolve the glitch and get it up and going again.

Symptoms of this glitch include the following:
  • the thermostat not working in the Nest App and disconnected from Wi-Fi
  • the thermostat tells you the battery is low and it needs to shut down
  • the thermostat’s animated features 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 black and unresponsive (you may also observe 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 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 cord plugged into a wall charger or a computer.

IMPORTANT: 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 Support says don’t do it, DO NOT DO IT.)

After about 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 thermostat. Once it has completed the restart, plug it back in to finish charging. After an hour of charging, disconnect the Nest Thermostat and restore it to its base.

You should be good to go and this point, but again, for more detailed instructions and information, please see Nest Support.

Also, do not let this issue concern you about your Nest’s reliability. By owning and properly operating Nest, your thermostat is actually saving money for you all hours of the day. When set it up correctly, Nest intelligently learns your lifestyle, then alters your heating and cooling use to optimize energy savings every day, which typically results in payback within the first year. And, Nest is still one of the only thermostats under $300 on the market that does this. So don’t let one complication get you down. You were smart to invest in a Nest, because a smart thermostat is still one of the leading investments in your home that you can make.
