Replacing a Water Heater Thermostat in 8 Steps

Remember, this is for electric water heaters:

1.Safety first, cut the power off at the breaker.

2.Remove the access panel(s) and insulation so you can access the thermostat(s). You may have one or two access panels. Most water heaters have two elements/thermostats.

3.Use the voltage meter to make sure the power is completely off.

4.Take a picture of the wiring within each panel so you can reference it later when you're putting everything back together.

5.Remove the wiring from the thermostat.

6.You need to remove the entire bracket that holds the thermostat in place. Pry out each side one at a time using a twisting motion, but be gentle. Don't force it, or you can break it. You don't want to have to replace that part too, so take your time with this step and get it right.

7. Deslice el nuevo termostato en el soporte, vuelva a colocar el soporte en su lugar y vuelva a colocar el cableado.

8. Vuelva a encender y deje tiempo para que su tanque se caliente.
