Thank you for contacting us! If the water level dropped and exposed the heater, this may have caused an issue. Make sure the tank is covered appropriately, at all times, as well. And last, check the temperature with a second thermometer as the first one may not be working properly. Assuming that it is working correctly, did the house get cooler due to a cold front, weather wise? If you are unable to resolve this issue, please call us at 1-800-322-1266 so we may assist you.
