Gas furnaces rely on a pilot light to ignite the main burner, providing heat for your home. If your furnace isn’t producing warmth, a faulty pilot light could be the culprit. Newton Heating and Plumbing offers expert advice on how to identify and fix pilot light issues safely and effectively.

Signs of a Faulty Pilot Light

Before attempting any repair, recognize the signs indicating a problem with your pilot light:

  • The pilot light is out or keeps going out.
  • The furnace isn’t producing heat when turned on.
  • The pilot flame is weak, flickering, or yellow instead of blue.
  • You notice a gas smell near the furnace.

Safety Precautions

Working with gas appliances can be dangerous. Always prioritize safety:

  • Turn off the gas supply before inspecting or repairing.
  • Ensure proper ventilation in the area.
  • If you smell gas, evacuate immediately and contact professionals.
  • Consider hiring a licensed technician if you’re unsure about any step.

How to Relight Your Pilot Light

If your pilot light is out and it’s safe to proceed, follow these steps:

  • Locate the pilot light assembly, usually near the bottom of the furnace.
  • Turn the gas control knob to the “Off” position and wait 5 minutes to clear any accumulated gas.
  • Set the control knob to “Pilot.”
  • Use a long lighter or match to ignite the pilot while holding down the pilot button.
  • Continue holding the button for about 30 seconds after the pilot lights.
  • Release the button and ensure the pilot remains lit.
  • Turn the gas control knob to “On” and restore power if needed.
