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

January 18, 2016

If you have a Nest Thermostat you probably read about the recent issues 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 an informative 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 more detailed instructions, go to their Nest Support page. For a more basic summary, keep on reading:

Nest Thermostats that were updated recently to software version 5.1.3 or later may have some problems, including becoming unresponsive, not correctly charging the battery, or turning off completely. Nest recommends recharging and restarting your thermostat to fix the issue and get it up and working 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 shut down
the thermostat’s animated properties 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 system(s)

If your Nest Thermostat will turn on but you can’t control it or it’s 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 manually restart 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, LISTEN TO THEM.)

After about 10 minutes of charging, detach the Nest Thermostat from the USB cord. If the unit has turned on during this time, turn it off and then turn it back on again, manually restarting the Nest. Once it has completed the restart, plug it back in to complete charging. After about 60 minutes of charging, unhook the Nest Thermostat and reattach it to its base.

You should be good to go at this point, but if you're done with Nest and want to switch your thermostat, you can see our comparison of common thermostats.

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.
