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 76.7 degrees Celsius. 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 centre 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.
Tips and warnings
- The thermal switch is not to be confused with the energy cut-off switch, also known as the high-temperature limit switch, found in Whirlpool gas water heaters. Though a thermal switch and high-temperature limit switch perform similar functions, the high-temperature limit switch is a single-use safety switch that must be replaced by a professional once activated. Contact Whirlpool's owner centre to schedule an appointment for service.
