White-Rodgers manufactures a full line of home thermostats. The White-Rodgers brand is one of the most common brands found in homes. One way to save on home energy costs is to update the old thermostat in your home. Replacing your current thermostat with a programmable unit allows you to set different temperatures throughout the day based on your lifestyle. Replacing the thermostat begins with removing your old one. Removing a White-Rodgers thermostat from the wall involves generally the same procedure as removing any other brand.
Turn off the power to your heating and air conditioning system. The circuit breaker is located in the electrical panel box. Switch the breaker to the "Off" position.
Remove the thermostat's faceplate cover. Depending on the White-Rodgers model you have, the cover either pops off or slides up.
Find the screws that secure the thermostat body to the mounting base. Remove the screws, using a Phillips-head screwdriver. Pull the base away from the mounting plate.
Place pieces of masking tape around each individual wire connected to the thermostat. There is a letter designation by the end of each wire on the thermostat. Write the letter designation for each wire on the tape, using a pencil. This will help guide you when you're installing the new thermostat.
Disconnect the wires from the back of the thermostat one at a time. Some White-Rodgers units use terminal screws to secure the wires, requiring a Phillips-head screwdriver. Others use a quick-connect tab to secure the wires. Press the quick-connect tab back with your thumb and pull the wire away from the thermostat.
Wrap all of the wires around a large nail or a pencil. This prevents the wires from slipping into the wall cavity. If necessary, tape the wrapped wires to the pencil or nail.
Remove the screws that secure the mounting plate, using the screwdriver. Carefully thread the pencil or nail with the wires through the mounting plate. The old thermostat is now removed from the wall, and you are ready to install a new one.
