How to Reset the Thermal Switch on a Whirlpool Water Heater

Whirlpool has earned a reputation for providing homeowners with safe, quality appliances at affordable prices. Whirlpool electric water heaters are equipped with a helpful safety feature called a thermal switch, which disrupts the flow of electricity to the water heater's heating elements when the water temperature exceeds 170 degrees Fahrenheit. Once the thermal switch has been activated, it must be reset before your Whirlpool water heater can begin heating again.
