How to Check the Furnace Pilot Light: 1 Minute to Safety: A Quick Guide to Furnace Maintenance

The furnace pilot light is a small, continuously burning flame that ignites your furnace’s burners when heat is called for. If your furnace stops producing heat or won’t turn on, a faulty or extinguished pilot light is often the culprit. Knowing how to check the furnace pilot light is an essential skill, especially during the colder months.

Step-by-Step Guide to Checking a Furnace Pilot Light

1. Turn Off the Furnace
2. Always start by turning off your furnace at the thermostat, and for additional safety, switch off its power source.
3. Locate the Pilot Light
4. Most pilot lights are near the bottom of the furnace behind a removable access panel. Look for a small tube and a burner assembly.
5. Inspect the Area Around the Pilot Light
6. Check for the smell of gas. If you detect a strong odor, leave immediately and contact your gas company.
7. Check the Pilot Light
8. A healthy pilot light burns blue with a small yellow tip. If it’s out, follow the manufacturer’s instructions to relight it, often found on a sticker inside the furnace panel.
9. Relight if Necessary
10. To relight:
11. Turn the gas control knob to “off” and wait 5 minutes for gas to dissipate.
12. Turn the knob to “pilot” and press it down while lighting the pilot with a match or igniter.
13. Continue holding the knob for 30 seconds, then release.
14. If the light stays on, turn the knob to “on” and restore power.
15. Observe the Flame
16. If the pilot light won’t stay on, there may be an issue with the thermocouple or gas supply. For safety, call a professional if the issue persists.

As an interior designer, I believe that home maintenance and safety are crucial components of a comfortable living space. Being proactive with tasks like checking your pilot light not only ensures reliable heating but also maintains the integrity and value of your home. Many modern home systems now integrate digital tools to simplify this process. For those who enjoy planning efficient layouts and integrating technology, using a home designer tool can help visualize safe, functional utility areas like furnace nooks in your home design, offering both safety and style.

Tips 1:

Always keep the furnace area clear of debris and dust for improved performance and safety. Schedule regular inspections and consider upgrading to a digital thermostat for easier monitoring of your heating system.
