Step 1: Turn Off the Power
Before you begin, make sure you turn off the power to the water heater. You can do this by turning off the circuit breaker or removing the fuse that powers the water heater.
Step 2: Drain the Tank
Next, you’ll need to drain the tank. This will prevent water from spilling out when you remove the thermostat. Attach a garden hose to the drain valve at the bottom of the tank and run it to a floor drain or outside.
Step 3: Remove the Thermostat
Locate the thermostat on the side of the tank and remove the cover. You may need to use a screwdriver or pliers to do this. Once the cover is off, disconnect the wires from the thermostat and remove it from the tank.
Step 4: Install the New Thermostat
Take the new thermostat and attach the wires to the same terminals as the old thermostat. Then, place the thermostat back into the tank and secure it with the cover.
Step 5: Refill the Tank
Once the new thermostat is installed, close the drain valve and turn on the cold water supply to refill the tank. Make sure to open a hot water faucet to allow air to escape while the tank is filling.
Step 6: Turn On the Power
Finally, turn the power back on to the water heater by flipping the circuit breaker or replacing the fuse. Wait for the water to heat up and test the temperature to ensure it’s working correctly.
