    Solution

    Dirty pilot orifice

    Dust or debris blocking the flame

    Clean the pilot orifice with compressed air

    Faulty thermocouple

    Worn-out or damaged thermocouple

    Replace the thermocouple

    Gas supply issues

    Low gas pressure or closed gas valve

    How to Relight the Pilot Light

    1. Turn Off the Gas Supply
      • Locate the gas valve and turn it to the "Off" position.
    2. Wait for Gas to Dissipate
      • Wait 5–10 minutes to allow any residual gas to clear.
    3. Locate the Pilot Light Assembly
      • Remove the access panel to expose the pilot light and gas control valve.
    4. Relight the Pilot Light
      • Turn the gas valve to the "Pilot" position.
      • Press and hold the pilot button while using a long lighter to ignite the pilot light.
      • Continue holding the pilot button for 30–60 seconds to allow the thermocouple to heat up.
      • Release the button and check if the pilot light stays lit.
    5. Turn the Gas Valve to "On"
      • Once the pilot light is stable, turn the gas valve to the "On" position.
