There’s nothing more frustrating than your heating controls suddenly not working on a cold, wintry day! Don’t worry … we’re here to help. We’ve provided step by step instructions on how you can reset your White Rodgers thermostat to get your heating back up and running.

What’s your Model?

Reset instructions differ per thermostat model so ideally, you should know the specific model to get the most accurate instructions.

If you do not know your model number, we have included imagery of each thermostat below to help guide you.

Typically the model number is printed on the back of the thermostat cover plate, which requires you to remove the cover to see it. Simply grasp the front cover and pull away from the wall plate to read it. Be careful as wiring may be exposed with the cover plate removed.
