How to restart or reset a Nest thermostat

When you restart your thermostat, it can resolve some issues, like a slow or frozen display, or help it get reconnected to the internet. If you need to clear out some or all of the learning about your home, schedule, or personal settings, you can reset your Google Nest thermostat.

Differences between restart and reset

Restart your Nest thermostat

  • Maintains all your settings, similar to when you restart a computer, phone, or tablet.
  • Is a useful troubleshooting step if your thermostat is stuck or frozen, has trouble connecting to the internet, or is not working normally.

Reset your Nest thermostat

  • Erases some or all of your thermostat’s information depending on the option you choose.
  • Is useful if you’re moving out and need to install your thermostat in a new location, or want to leave your thermostat behind and you want to remove all your personal information.
How to reset or restart your Nest thermostat

Important: Before you reset your thermostat, write down the settings so you can easily restore them if needed. Go to Settings Nest settings icon and then Equipment on your thermostat and record your system wires, your heating type, and your Safety Temperature settings.

  1. Press your thermostat ring to open the Quick View menu.
  2. Choose Settings Nest settings icon.
  3. Turn the ring to Reset and press to select.
  4. Choose your option from below.
Restart Your Nest thermostat will not lose any of your information or settings if you restart it, similar to a computer, phone or tablet. Your thermostat will boot back up, and you can continue to use it.

If you choose this option, it will clear out your entire temperature schedule. Do this if you want your thermostat to start learning a new schedule.

Any set points that your thermostat has learned, or that you’ve created, will be erased. You’ll need to create a brand new schedule from scratch, or wait while your thermostat learns your new schedule.

Note: If you’re using a Nest Thermostat E and you have Auto-Schedule disabled you’ll find the option to reset to a blank schedule as above or choose Basic Schedule. A Basic Schedule is a pre-filled schedule based on a national average that balances energy-savings and comfort.


Your thermostat learns how often you walk by to help your connected devices automatically switch as you come and go. If you reset Away on your thermostat, everything it has learned about when you're home or away will be reset.

Use this reset option if you move your thermostat to a new location in your home, or if you've had your home remodeled. Your thermostat will learn about its new location in a few days.

Tip: You can improve Home/Away Assist by using your phone location.

Account connection

This option may not appear depending on your thermostat’s software version.

If you’re moving and leaving your thermostat behind

You should remove your account connection without resetting other settings. You may also want to reset your schedule before moving. This will let the new owners control the system from day one while the thermostat learns a schedule for them.

After you reset the account connection 

You’ll still find your thermostat in the app, but it will be listed as “offline” and can no longer be controlled with the app. To remove it from your account and the app, go to the thermostat’s settings in the app and select Remove thermostat.

WWN Connection

This option may not appear depending on your thermostat’s software version.

If you have Works with Nest (WWN) devices that are connected to your thermostat, they may have stopped working. 

  • If you haven’t migrated to a Google Account, you can restore the WWN functionality:
    1. Remove the thermostat from your account.
    2. Reset the WWN connection with this option.
    3. Add your thermostat to your account again.
  • If you’ve already migrated to a Google Account, use the Google Home app to connect your device via Works with Google Assistant:
    1. On the Home app's main screen, tap Add .
    2. Tap Set up device.
    3. Browse the Works with Google list for your WWN device and select it. Then follow the app’s instructions.

This option may not appear depending on your thermostat’s software version.

If you reset the network, it will remove all of the network information from your thermostat. Your thermostat will no longer be connected to the internet and it will forget your Wi-Fi password.

To connect your thermostat back to the internet, you’ll need to select your Wi-Fi network from the Settings Nest settings icon and then Network menu.

All Settings

If you reset your Nest thermostat to defaults, it will reset any learning and remove all your personal settings.

Important: You should remove your thermostat from your account before using this option to reset to defaults.

Your thermostat will need time to learn about you and your home before creating your schedule and activating its energy saving features.

How Nest thermostats learn

You'll also need to add your thermostat to the Nest app again if you’d like to be able to use it remotely and receive alerts.

Note: If you have any Nest Temperature Sensors, resetting your thermostat does not remove them from your account.

How to manually restart if your Nest thermostat is frozen 

This method is only recommended if your thermostat is stuck or frozen, and you can’t reach the menu to restart your thermostat as described in the section above.

Important: Manually restarting your thermostat is similar to turning off a computer instead of shutting it down, so your thermostat could lose some unsaved information.

To manually restart your Nest thermostat:

Nest Thermostat E and 3rd gen Nest Learning Thermostat

  1. Press the ring on your Nest Thermostat E or Nest Learning Thermostat (3rd gen) and hold it down until the screen turns off (about 10 seconds). Then, let go of the ring. The Google or Nest logo will appear when it begins to start up. The screen will turn on as it finishes.

2nd gen Nest Learning Thermostat

  1. Press the ring on your Nest Learning Thermostat (2nd gen) and hold it down until the screen turns off (about 10 seconds). Then, let go of the ring.
  2. Press and release the ring to turn it back on and complete the restart process. The Nest logo will appear when it begins to start up. The screen will turn on as it finishes.
