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

January 18, 2016
If your home has the Nest Thermostat you have probably read about the recent outages and may be living in fear of being left without heat in the dead of winter.

But fear no more!

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.” Obvious, much?

For complete instructions, see Nest Support page. For a quick 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 have been having some issues, including becoming unresponsive, not efficiently charging the battery, or turning off completely. Nest recommends recharging and restarting your thermostat to rectify the glitch and get it up and working again.

Signs of this issue include the following:
  • the thermostat being offline in the Nest application and disconnected from the Wi-Fi
  • the thermostat alerts 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 notification that says, “Please remove the thermostat from its base, then reattach it;”
  • the thermostat’s display is dark and unresponsive (you may also have 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 running 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 a USB charger plugged into the wall or a computer.

ATTENTION: Do not try to power on or off your thermostat while it’s still connected to a computer for charging. (They didn’t explain why, but if they say don’t do it, DO NOT DO IT.)

After approximately 10 minutes of charging, disconnect the Nest Thermostat from the USB charger. If the unit has turned on while plugged in, turn 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, disconnect the Nest Thermostat and reconnect it to its base.

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