Having a furnace in your home is essential for keeping you warm during the cold winter months. However, if your furnace suddenly stops working, it can be quite frustrating. One common issue that homeowners face is a pilot light that has gone out. In this article, we will discuss where the furnace pilot light is located and how you can relight it.

Locating the Furnace

The first step in finding the furnace pilot light is to locate your furnace. Most furnaces are found in the basement, attic, or a dedicated furnace room. Once you have found your furnace, you can begin searching for the pilot light.

Understanding the Furnace Components

Before we dive into locating the pilot light, it’s important to have a basic understanding of the furnace components. The pilot light is a small flame that ignites the gas burners in your furnace. It is usually located near the bottom of the furnace and is protected by a small cover.

Checking the Furnace Manual

If you’re having trouble finding the pilot light, the first thing you should do is consult your furnace manual. The manual will provide you with detailed information about the location of the pilot light for your specific furnace model. You can usually find the manual online if you don’t have a physical copy.

Locating the Pilot Light

Now that you have a general idea of where the pilot light might be, it’s time to locate it. Start by removing the furnace cover. This can usually be done by unscrewing a few screws or lifting a latch. Once the cover is off, you should be able to see the burners and the pilot light assembly.

Identifying the Pilot Light

The pilot light is a small, blue flame that is usually located near the burners. It is often housed in a metal tube or a small chamber. Some furnaces have a window that allows you to see the pilot light without removing the cover. If your furnace has this feature, you can skip removing the cover and simply look for the flame through the window.

Relighting the Pilot Light

If you have located the pilot light and it is not lit, it’s time to relight it. Start by turning the gas control knob to the “off” position and wait for at least five minutes to allow any gas to dissipate. After the waiting period, turn the knob to the “pilot” position.

While holding down the knob, use a long lighter or match to ignite the pilot light. Once the flame is lit, continue holding the knob down for about 30 seconds to allow the thermocouple to heat up. Afterward, you can release the knob, and the pilot light should stay lit.


Knowing where the furnace pilot light is located can save you time and frustration when it comes to troubleshooting your furnace. By following the steps outlined in this article, you should be able to locate and relight the pilot light on your own. However, if you’re uncomfortable with the process or if the pilot light continues to go out, it’s best to contact a professional HVAC technician for assistance.
