How Do I Replace My Water Heater Thermostat?

Replacing your water heater thermostat is as simple as removing the old thermostat from the brackets and putting in the new one! Once you’ve got a new thermostat to replace the old one, start by locating the water heater breaker in the electric panel and turn it off. If there is a disconnect, pull it. Use a volt meter or voltage detector to make sure the power is turned off before doing any repairs. Now you can by remove the safety cover. The brackets that hold the old thermostat need to be moved so the old thermostat can be changed. This is a simple process, as long as you have the right tools.

Say Bye to the Brackets

Your water heater thermostat is held in place by brackets: when you remove the safety cover, you’ll see your thermostat and what’s keeping it in place. Carefully remove the old thermostat from the brackets by pushing out the brackets and gently pulling the thermostat up and out of the holders.

After removing the old thermostat, gently slide the new thermostat into place. Make sure the new thermostat is locked into the holding brackets, put the wiring back according to the picture you took, replace the safety cover, and turn back on the power so you can test your new thermostat.
