Home Repair Parts Replacement Bradford Red Water Heater Temperature Thermal Reset Safety Switch

If your water heater has stopped heating, a tripped thermal switch may be to blame. In water heaters and many other types of home appliances, thermal switches disrupt power to the appliance's heating mechanisms when the appliance starts to overheat. Most thermal switches are triggered when the temperature of the water in the tank rises above 170 degrees Fahrenheit. While resetting the thermal switch on your water heater will allow it to operate again, the thermal switch may continue to trip if the underlying problem is not solved.
