Richmond Water Heater Thermostat Replacement [7 Easy Steps]
Tools or Equipment You Need:
- A new thermostat. Ensure the new thermostat is the same type of thermostat you are going to replace. Remember that the upper thermostat is not the same as the lower thermostat.
- A #2 Phillips screwdriver
- Flat blade screwdriver
- A voltmeter
Once you get these pieces of equipment at your fingertips, walk through these steps to have the thermostat replaced like a pro:
1. Turn off the electric power to your water heater at the circuit breaker before servicing the water heater. Failure to do so may result in electric shock, personal injury, or loss of life.
2. Remove either the upper or the lower access panel depending on the thermostat you are going to replace. If you want to replace the lower thermostat, use a screwdriver to unscrew the lower cover panel. Then, remove the insulation and the plastic protective cover to expose the thermostat.
3. Detach the thermostat wires. Tag the wires before pulling them out from the screw terminals to correct the thermostat wiring later. You can also take a snapshot of the thermostat wiring so that you can eliminate incorrect wiring of the thermostat.
4. Remove the thermostat by lifting it out of the retaining bracket. Be careful not to pull out the retaining bracket too hard. Breaking the retaining bracket will require you to replace the entire water heater.
5. Install the new thermostat. Verify that the back of the thermostat is pressing tightly against the tank because that affects the accuracy of the temperature reading.
6. Rewire the tagged leads to the proper screw terminals. Double check the wire connections and ensure they are correct, firm, and tight. Replace the plastic protective cover.
7. Finally, adjust the new thermostat so the water temperature doesn’t exceed 120 degrees Fahrenheit. I already published an article on Richmond Water Heater Temperature Adjustment. Read that article to learn how to adjust the temperature on Richmond Water Heater. Complete the replacement workflow by replacing the cover access panel. Then, restore the power to the water heater at the circuit breaker.

- Insufficient hot water: Again, it indicates that the culprit is the upper thermostat.
- Too hot water: If you calibrate or set the upper thermostat incorrectly, you will get excessive hot water from your water heater.
- It takes a while to get hot water: If you turn on a hot water faucet but get hot water after a long time, I bet the lower thermostat is at fault.
