What Causes A Water Heater Pilot To Go Out - Electronic or direct spark pilot lights rely on an electrical current or a strike against conductive metal to come to life. A primary cause is a faulty thermocouple, which is a safety device that detects whether the pilot light is lit. The thermocouple within your water heater senses when your pilot light is burning. The pilot light going out on a water heater is typically caused by a faulty thermocouple or insufficient air supply.
