Gather the Tools and Materials

To replace a water heater sensor, you will need the following tools and materials: Pliers, a new sensor, and flathead or Phillips head screwdrivers.

You can purchase these tools and materials from hardware stores. Once you have gathered all the necessary supplies, you are ready to start replacing the temperature sensor.

Shut off the Water Supply and Turn off the Power Supply

To replace a water heater’s thermal sensor, begin by shutting off the water supply. This is to prevent water from entering the heater and potentially causing a flood.

After turning off the water, you should then turn off the power supply to the heater. This can be done by flipping the circuit breaker or removing the fuse from the fuse box.

Remove the Old Temperature Sensor

Now it’s time to remove the old temperature sensor. The sensor is located near the top of the tank on the inside, so you may need a flashlight to see it.

Once you locate it, use the screwdrivers or pliers to loosen and remove the nut that holds it in place. Then, pull out the old sensor and discard it.

Install the New Temperature Sensor

Once the old sensor is out, you’ll need to put the new one in its place and screw it in tightly. Make sure that you don’t overtighten it, as this can damage the new sensor. Be sure all the wiring harnesses are connected before turning the power back on to the water heater.

Test the New Temperature Sensor

To test the new sensor, put your thermometer in the water heater and compare it to the temperature gauge on the sensor. Adjust the temperature gauge on the sensor until it is accurately displaying the current water temperature in the water heater.

Once the temperature gauge is calibrated, you’re ready to use your water heater. You can also check this rheem water heater temperature control to learn how to do more calibration.
