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.
Locate the control circuit on the side of your Whirlpool water heater. The control circuit is a rectangular panel where the safety controls for your water heater are located.
Look for a large red button at the center of the control circuit panel on your Whirlpool water heater.
Reset the thermal switch on your Whirlpool water heater by pressing and holding the large red button for at least three seconds.
