How to Relight Pilot Light on Old Furnace
Relighting a pilot light on an old furnace can be a challenging task, but it’s a crucial step to ensure your home stays warm and cozy during the cold winter months. In this article, we’ll guide you through the process of relighting the pilot light on your old furnace.
Why Is the Pilot Light Important?
The pilot light is a small flame that ignites the gas burner in your furnace. It’s responsible for keeping the system running smoothly and efficiently. Without a working pilot light, your furnace won’t be able to produce heat, and you’ll be left without a reliable source of warmth during the cold winter.
Before You Start
Before you begin the process of relighting the pilot light, make sure you:
- Turn off the gas supply to the furnace. This can usually be done by finding the shut-off valve near the furnace and turning it clockwise.
- Ensure that the furnace is cool to the touch. This will prevent any accidental burns or injuries.
- Have a flashlight or lamp nearby to illuminate the area.
Step-by-Step Instructions
Relighting the pilot light on your old furnace involves several steps. Here’s a step-by-step guide to help you through the process:

Step 1: Access the Pilot Light Assembly
- Locate the pilot light assembly. It’s usually located on the side of the furnace or near the bottom. You may need to remove a panel or cover to access it.
- Look for the pilot light pilot orifice. This is the small opening where the pilot light flame emerges.
- Use a screwdriver or Allen wrench to loosen any screws or clips holding the pilot light assembly in place.
Step 2: Turn the Pilot Light Knob
- Locate the pilot light knob. It’s usually located near the pilot light assembly and is labeled "pilot" or "spark".
- Turn the pilot light knob counterclockwise to turn off the pilot light. This will allow you to relight it.
- Hold the knob in place with your finger or a small tool to prevent it from spinning back up.
Step 3: Light the Pilot Light
- Hold a lit match or lighter near the pilot light pilot orifice.
- Slowly turn the pilot light knob clockwise while holding the flame near the orifice. This will allow the pilot light to ignite.
- Keep the flame in place until the pilot light is burning steadily.
Step 4: Check the Pilot Light
- Once the pilot light is lit, check to ensure it’s burning steadily. If it’s not, you may need to adjust the pilot light knob or clean the pilot light pilot orifice.
- Verify that the pilot light is producing a stable, steady flame.
Troubleshooting Tips
If you’re having trouble relighting the pilot light, try the following troubleshooting tips:
- Make sure the gas supply is turned on: If the gas supply is turned off, the pilot light won’t be able to ignite.
- Check for blockages: Blockages in the pilot light pilot orifice can prevent the pilot light from igniting. Try cleaning the orifice with a small brush or toothpick.
- Check the pilot light knob: Make sure the pilot light knob is not stuck or damaged. Try cleaning or replacing it if necessary.
