Wondering how to reset an Emerson thermostat? You’re in the right place. When a thermostat gets stuck it causes problems for your HVAC (heating ventilation air condition) system. You won’t be able to change the temperature of your home and this causes discomfort in hot summer months or cold winter months. Therefore, learning how to reset your thermostat can help you solve common thermostat bugs and glitches on your own. Unfortunately, the alternative would be calling someone from the company, sitting on hold, or calling an electrician. 

The good news is that we’re here to help. We’re going to take you through everything you need to know about these Emerson thermostats and how to reset them. We’ll also be covering Sensi and White Rodgers thermostats as well. 

Emerson, Sensi, and White-Rodgers: What’s the Difference?

Emerson, Sensi, and White-Rodgers thermostats are produced by Emerson.

While Emerson produces its own line of thermostats, Sensi and White-Rodgers are also owned by Emerson.

The difference between the brands comes down to a few factors. 

First and foremost, Sensi is a brand of luxury thermostats.

These are thermostats that feature touchscreens, smart technology, WiFi capabilities, and companion apps.

On the other hand, White-Rodgers thermostats are more traditional. While there are some advanced models, White-Rodgers thrives on ease of use and simple design. Emerson thermostats are a combination of the two and Emerson is the parent company of White-Rodgers and Sensi.

Emerson owns all of the brands but each thermostat has different functionality and designs.

This means that manuals for Emerson thermostats won’t always work for White-Rodgers or Sensi products. Therefore, it’s important to know if you have a Emerson, White-Rodgers, or Sensi thermostat before attempting a reset. You can determine which brand by looking for the logo or name of the brand on the cover plate, top plate, or rear plate.

Read on to learn more about how to rest Emerson, White-Rodgers, and Sensi thermostats.

What You Need to Know Before Resetting Your Thermostat 

Before resetting your thermostat there are a few things you need to do. You want to find the model number and read the owner’s manual.

Check the Owner’s Manual 

The owner’s manual comes with every Emerson thermostat, even older models. Locating and reading the owner’s manual is crucial because it can take you through the steps to reset the thermostat.

Moreover, it can help you diagnose issues with the thermostat that might not require a reset. The good news is that if you lost the owner’s manual there is a good chance you can find a copy of one online. Simply enter your model number into Google and you’ll be able to find the manual. 

For this to work, though, you’ll need the model number.

Locate the Model Number 

The model number shows you what model of thermostat you have. Model numbers are important because every model has different technology, problems, and reset methods. While the model number is not always listed on the front of the thermostat, the model number can be found on the back or sides of most Emerson thermostats. 

With the model number, you can determine the steps necessary to reset the thermostat or access the owner’s manual online.
