Finding the pilot light on a furnace can be crucial for troubleshooting heating issues or performing maintenance. The pilot light is a small flame that ignites the burner to heat your home. Knowing where it is located and how to identify it safely ensures efficient furnace operation. This guide provides clear steps and tips to help homeowners locate the pilot light quickly and safely.
| Furnace Type | Pilot Light Location | Additional Notes |
|---|---|---|
| Standing Pilot Furnace | Near the burner assembly, accessed through the front panel | Has a small flame visible after opening the furnace door or panel |
| Intermittent Pilot / Electronic Ignition | No constant pilot light; ignition occurs automatically | Users should check the igniter instead of a pilot light |
Understanding Different Types of Furnace Ignition Systems
Traditional furnaces use a standing pilot light, a small, continually burning flame that ignites the gas burner. Newer models often employ an electronic ignition system or intermittent pilot, which does not maintain a constant flame but ignites only when heating is required.
Knowing your furnace type is the first step to locating or troubleshooting the pilot light. Standing pilot lights are visible and accessible, usually inside the burner compartment. In contrast, electronic ignition systems omit the pilot flame and rely on electric sparks or hot surfaces.
Steps To Locate the Pilot Light on a Traditional Furnace
Locating the pilot light on a furnace requires basic safety precautions and some knowledge of furnace components:
- Turn off the furnace and gas supply: Ensure power to the furnace and gas valves are off to avoid any accidents during inspection.
- Open the furnace access panel: Use a screwdriver if necessary to remove the front panel or door, revealing the burner assembly.
- Look for the burner assembly and pilot light tube: The pilot light is typically adjacent to the burners, attached to a thin metal tube where gas flows.
- Identify the pilot flame: The pilot is a small, steady flame usually blue with a yellow tip and is significantly smaller than the burner flame.
Common Pilot Light Locations in Popular Furnace Brands
| Brand | Pilot Light Location | Additional Tips |
|---|---|---|
| Carrier | Inside the main burner compartment behind the lower front panel | Look near the gas valve and pilot tube |
| Trane | Behind a removable burner access door on the furnace front | Usually near the bottom of the burner assembly |
| Goodman | Located near the gas control valve in the lower furnace compartment | May require removing the burner access panel |
| York | Behind an access panel on the front lower section of the furnace | Check close to the pilot adjustment knob |
Safety Tips When Handling Furnaces and Pilot Lights
Always prioritize safety when inspecting or relighting a pilot light. Follow these precautions:
- Turn off the furnace and wait 5-10 minutes before opening panels to allow gas to dissipate.
- Use a long match or lighter when relighting the pilot to avoid burns.
- Ventilate the area to avoid gas buildup.
- If you smell gas strongly, do not attempt to light the pilot; contact a professional immediately.
What to Do If You Can’t Find the Pilot Light
If you own a newer furnace, there might not be a pilot light at all. Models with electronic ignition systems or direct spark ignition ignite burners without a constant flame. In such cases, troubleshooting involves checking the igniter or control board instead.
For older models, if the pilot light isn’t visible after accessing the burner compartment, consult the furnace manual or contact certified HVAC professionals to avoid misdiagnosing the issue.

Why Proper Pilot Light Maintenance Matters
A properly functioning pilot light helps ensure your furnace operates efficiently and safely. A weak or flickering pilot light can signal gas supply problems, dirty burners, or pilot tube blockage.
Routine checks prevent carbon monoxide buildup, reduce energy waste, and prolong furnace life. Homeowners should schedule annual furnace inspections to maintain safe and reliable heating.
Summary: Quick Checklist for Locating Your Furnace Pilot Light
- Identify your furnace ignition type (standing pilot, electronic ignition, or intermittent pilot).
- Turn off power and gas before accessing the furnace.
- Open the front panel or burner access door to find the burner assembly.
- Look for a small metal tube with a tiny flame if it’s a standing pilot light furnace.
- Check your furnace brand’s manual for specific pilot light location instructions.
- Contact a professional if unsure or if the pilot light is hard to find or relight.
