Ao Smith Water Heater Pilot Will Not Light

If the pilot cannot be cleaned replace it.

Ao smith water heater pilot will not light. Smith water heaters including the conservationist model use a modern built in piezoelectric igniter system that allows you to light the pilot by pushing the ignition button. Occasionally the pilot light on your a o. If the pilot is restricted try removing it and clearing it with a stiff brush and or compressed air. Obstruction in the thermocouple thermocouple problems can be fairly common and this component is often the culprit when the water heater pilot keeps going out.
