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

January 18, 2016
If you have a Nest Thermostat you may have read 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 no more!

Nest Support has published an instructional 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 instructions, see Nest Support page. For a more basic overview, keep on reading:
Nest Thermostats that were updated recently to software version 5.1.3 or later have been having some issues, including becoming unresponsive, not correctly charging the battery, or shutting down completely. Nest recommends recharging and restarting your thermostat to rectify the problem and get it up and running again.

Indications of this glitch include the following:
  • the thermostat not working in the Nest’s mobile app and disconnected from the Wi-Fi
  • the thermostat tells you the battery is low and it needs to turn itself off
  • the thermostat’s animations 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 will turn 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.

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 around 10 minutes of charging, detach the Nest Thermostat from the USB cable. If the thermostat has turned on during this time, shut it down and then turn it back on again, manually restarting the system. Once it has fully restarted, plug it back in to reach full charge. After another 60 minutes of charging, detach the Nest Thermostat and reconnect it to its base.

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

Finally, do not let this matter concern you about your Nest’s reliability. By owning and properly using Nest, your thermostat is honestly saving money for you daily. When set it up properly, Nest intelligently learns your lifestyle, then adapts your heating and cooling use to optimize energy savings constantly, 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 incident get you down. You were smart to invest in a Nest, because a smart thermostat is still one of the prime investments in your home that you can make.
