Gas Water Heater Burner Lights Then Goes Out

In english that means a gas valve is slowed to continue to release gas for up to 30 seconds after the pilot fails.

Gas water heater burner lights then goes out. A dirty pilot light for gas heaters can also be the culprit for a water heater not remaining on. Burner lights and heats then goes out and takes pilot with it. The gas line is what provides fuel to the burner to keep it lit. Gas valve are allowed 30seconds to fall out.

When the water heater is first lit a valve releases gas into the burner and the pilot light ignites that gas. If you can light your pilot light but it keeps going out the first item to check is the thermocouple. Enough air still gets through to keep the pilot light lit. Similar to how if there is insufficient flow of gas to the pilot it won t stay lit a pilot tip that.

The first fix to try when the water heater burner goes out is simple. One black dial off push to pilot on w hot a notch marking b c d very hot temperature. Your gas valve is what delivers natural gas directly to your water heater. A complete blockage often prevents the burner from lighting at all.

Pull aside the filter fabric insert brush clean. But when the thermostat on the tank calls for the burner to fire up it fails because it is starved for air. If so replace the entire valve. First cut off the gas supply switch off your heater and wait for the thermocouple to cool off.

Gas from this valve lights your pilot light and eventually lights the gas burners that heat your water. The thermocouple will conclude that the pilot light is off and thus close the valve and cut off the gas supply. If your burner lights for a short time but then goes out you may have a blockage in the gas valve. You ll have to manually bend or straighten the thermocouple back to position.

But if this valve or its inner elements are damaged it can t deliver enough gas to your water heater causing it to shut on and off.
