If you find that your furnace’s pilot light won’t stay lit, don’t worry. As mentioned earlier, we’ll tell you how to relight a pilot light on an old furnace. Relighting a pilot light is a simple process that you can easily accomplish by following these step-by-step instructions:

1. Turn off the gas

Before you begin, make sure that the gas valve to your furnace is turned off to prevent any gas from escaping. This valve is usually located near the gas meter or gas pipe that enters your home.

2. Locate the pilot light

When your furnace is operating properly, the pilot light should be a small, blue flame that burns continuously. It is typically located near the bottom of the furnace, behind a small metal panel or door. If you’re having trouble finding it, consult your furnace’s user manual.

3. Remove the access panel

Once you’ve located the pilot light, remove the metal panel or door that covers it. This may require a screwdriver or other tool, but typically the panel can be removed by hand.

4. Wait a few minutes

After the panel is removed, wait a few minutes to allow any gas that may have built up to dissipate before proceeding. This will ensure that you don’t accidentally ignite any gas that has accumulated while the furnace was off.

5. Locate the pilot valve

The pilot valve is the control that regulates the gas flow to the pilot light. It is usually located next to or just above the pilot light itself.

6. Turn the pilot valve to “off”

You have to switch the pilot valve to the “off” position and wait for a few seconds. This will allow any remaining gas to clear out of the system.

7. Turn the pilot valve to “pilot”

Now turn the pilot valve to the “pilot” position and hold a lighted match or lighter to the pilot light opening.

8. Light the pilot

While you’re holding the match or lighter near the pilot light opening, press the button on the pilot valve to release gas. When the pilot light ignites, continue holding the button for a few moments to allow the flame to stabilize.

9. Turn the pilot valve to “on”

After the pilot light has been lit and is stable, turn the pilot valve to the “on” position. This will allow gas to flow to the furnace burners, which should ignite automatically.

10. Replace the access panel

Finally, replace the metal panel or door that covers the pilot light and turn the gas valve to the “on” position. Your furnace should now be running normally.

Maintaining the Pilot Light and Furnace

After successfully relighting the pilot light on your furnace, it is essential to understand the importance of regular maintenance to ensure its optimal performance and longevity. Here are some tips for maintaining the pilot light and furnace:

Regular cleaning ─ Over time, dust and debris can accumulate around the pilot light and other furnace components. It is crucial to clean these areas periodically to prevent blockages or obstructions. Use a soft brush or cloth to gently remove any dirt or buildup.
Inspect gas lines ─ As part of routine maintenance, inspect the gas lines connected to the furnace for any signs of damage or leaks. If you notice a gas odor or suspect a leak, immediately turn off the gas supply and contact a professional technician for assistance.
Check pilot light flame ─ Regularly check the pilot light flame to ensure it remains steady and consistent. A strong and steady flame indicates proper combustion. If the flame is weak, flickering, or keeps going out, it may be a sign of an underlying issue that requires attention from a professional.
Replace damaged components ─ If you notice any damaged or worn-out components during your maintenance inspection, such as a cracked thermocouple or a faulty pilot light assembly, it is crucial to replace them promptly. Faulty components can affect the performance of the pilot light and the overall functioning of the furnace.
Schedule professional maintenance ─ While you can perform basic maintenance tasks, it is highly recommended to schedule regular professional maintenance for your furnace. A qualified technician can thoroughly inspect, clean, and tune up your furnace, ensuring it operates efficiently and safely.

Safety Reminders

Lastly, here are some safety reminders to keep in mind when dealing with your furnace:

Always follow the manufacturer’s instructions and guidelines provided for your specific furnace model.
If you encounter any complex issues or feel unsure about performing maintenance tasks, it is best to seek professional help.
Before attempting any maintenance or repairs, turn off the gas supply and wait for any residual gas to dissipate.
Keep the area around the furnace clean and free from flammable materials.
Install carbon monoxide detectors near your furnace and throughout your home to ensure early detection of any gas leaks or combustion issues.
