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

January 18, 2016
If you purchased the Nest Thermostat you have probably heard about the recent problems and may be living in fear of being left without heat in the dead of winter.

But fear not!

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.” Yes, that’s really the title.

For complete instructions, see 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 have been having some problems, including becoming unresponsive, not correctly charging the battery, or turning off completely. Nest recommends recharging and restarting your thermostat to rectify the problem and get it up and running again.

Signs of this issue 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 turn off
  • the thermostat’s animated properties 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 observe a blinking red or green light above the display)
  • the thermostat can’t control the corresponding HVAC unit(s)

If your Nest Thermostat is turned on but you can’t control it or it’s acting sluggish, 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 NOTE: Do not try to manually restart 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, LISTEN TO THEM.)

After around 10 minutes of charging, unplug the Nest Thermostat from the USB cord. If the thermostat has turned on while charging, shut it down and then turn it back on again, manually restarting the system. Once it has restarted completely, plug it back in to fully charge. After another hour of charging, unhook 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, see Nest Support.
