Common Gas Water Heater Failure Symptoms
- Pilot Light Keeps Going Out: A dirty or malfunctioning thermocouple (or thermopile on electronic ignition systems) fails to generate the millivolt signal required to hold open the safety gas valve.
- Burner Flame Yellow or Sooty: A healthy gas burner produces a crisp blue flame. Yellow or orange flames indicate incomplete combustion, dirty burner orifices, or restricted airflow, posing a carbon monoxide risk.
- Banging or Popping Sounds: Heavy mineral sediment lying over the gas burner assembly insulates water at the bottom of the tank, causing localized boiling and loud popping noises during heating cycles. Schedule an annual water heater flush to clean out sediment buildup.
- Water Leaking from Draft Hood or Flue Pipe: Condensation dripping down the draft hood suggests backdrafting combustion exhaust, requiring immediate flue pipe inspection.
