Gas Stove Burner Flames Too High?

Troubleshooting and Solutions

If the flames on your gas stove burner are too high, it can be dangerous and cause uneven cooking. Here are some common reasons for this issue and steps to troubleshoot and fix it:

Common Causes:

  1. Incorrect Air-Gas Mixture:

    • The air shutter might be adjusted incorrectly, affecting the air-gas mixture and resulting in high flames.
  2. High Gas Pressure:

    • The gas pressure might be set too high, causing excessive flames.
  3. Faulty Pressure Regulator:

    • The pressure regulator, which controls the flow of gas to the burners, might be faulty.
  4. Improper Burner Orifice:

    • The burner orifice might be the wrong size, allowing too much gas to flow through.
  5. Clogged Burner Ports:

    • Clogged burner ports can cause the gas to flow unevenly, resulting in high flames.

Troubleshooting Steps:

  1. Adjust the Air Shutter:

    • Locate the air shutter on the burner tube, which is typically near the burner valve.
    • Adjust the air shutter to increase or decrease the amount of air mixed with the gas. Properly adjusted flames should be blue and steady.
    • Test the burner after each adjustment to see if the flames are properly regulated.
  2. Check the Gas Pressure:

    • If you suspect the gas pressure is too high, contact your gas provider or a professional technician to check and adjust the gas pressure to the correct level.
    • Do not attempt to adjust the gas pressure yourself if you are not experienced, as it can be dangerous.
  3. Inspect the Pressure Regulator:

    • The pressure regulator controls the flow of gas to the stove.
    • Locate the pressure regulator (usually near the gas line connection) and ensure it is functioning properly.
    • If you suspect the pressure regulator is faulty, consider replacing it. Consult the stove's manual for the correct part and replacement procedure.
  4. Verify the Burner Orifice Size:

    • Check the burner orifice size to ensure it matches the specifications for your stove model.
    • If the orifice is too large, it will allow too much gas to flow through, resulting in high flames.
    • Replace the orifice with the correct size if necessary.
  5. Clean the Burner Ports:

    • Turn off the stove and let it cool completely.
    • Remove the burner caps and grates to access the burner ports.
    • Use a small brush or a pin to clean any debris or clogs from the burner ports.
    • Ensure all ports are clear and free of obstructions.
