Restart your thermostat following a power issue or malfunction
Resetting your White Rodgers thermostat is a smart move after a power outage or if the screen and temperature controls stop responding.

No matter the reason, this guide covers how to reset various White Rodgers models including the 70 and 80 Series, Sensi Touch Smart, and others.

- Sensi Smart Thermostat: Simultaneously press the up, down, and Fan buttons.
- Sensi Touch Smart Thermostat: Navigate to the Menu and select Factory Reset.
- Sensi Lite Smart Thermostat: Hold down the up, down, and Menu buttons at the same time.

Reset Instructions for a Blue Series Thermostat
Reset steps vary depending on the Blue Series model you own. Some models, like the 12" and 6", reset when you press the up, down, and SYSTEM buttons together.

If Your Thermostat Still Won’t Reset
Try replacing the batteries. A failed reset could simply mean the batteries are drained. Detach the thermostat faceplate and insert a fresh set of batteries. If low power was the issue, your device should power back on instantly—then you can adjust it to your preferred temperature.
Consider replacing the thermostat. If fresh batteries and the correct reset procedure haven’t resolved the issue and your unit still won’t function, it’s likely time for a replacement. You can install a new thermostat by ordering directly from Copeland, the parent company of White Rodgers, or find one available on Amazon.
