How to Reset White Rodgers/Emerson Thermostat

Your thermostat is an essential component of your housing system as it regulates the ambient temperature of your home depending on the season. So, when it fails, a plethora of problems arise. You lose control over the temperature in your own home. You will feel chilly in winter and will sweat in the summer.

The buttons on the thermostat can be confusing and so can be the configurations if you are not tech-savvy. While there are many brands of thermostats available in the market, White Rodgers or Emerson thermostats are the popular ones. So, we will provide you with all the steps necessary to reset that.

The process may differ depending on the model of the thermostat. But, this post will try to cover most of the popular brands. So stay tuned in.

Check your White Rodgers or Emerson Thermostat model first!

There are different thermostat models available manufactured by Emerson. So, you need to take time and find out the exact model of the thermostat at your home. This will allow you to reset your thermostat rather quickly and swiftly without any confusion.

  • The model number of your Emerson thermostat is often written on the thermostat itself and also on the manual that came along with the device.
  • In most cases, the model number can be retrieved from the cover plate of the thermostat which is placed at the back of the device. You will have to remove the front cover to see it.
  • To do the same, hold the cover and pull it away from the wall where the thermostat is attached. You will find the model number written there.
  • If you are still unsure about it, you can check online on different websites or the official website of the manufacturer.
  • When you are sure, write it down and keep it somewhere safe so that you don’t have to go through the trouble of finding it again.

Note: When you are about to remove the front cover from the device, you need to be careful as the electrical wiring is exposed. Make sure there are no children around to avoid any electrocution and you need to be extra cautious about yourself as well.
