Where to Find Pilot Light on Furnace: A Comprehensive Guide
When it comes to heating and cooling your home, having a functioning furnace is crucial. But sometimes, things can go wrong, and you might notice that your furnace isn’t producing any heat. This is where the pilot light comes in. In this article, we’ll help you understand what the pilot light is, why it’s essential, and where to find it on your furnace.
What is a Pilot Light?
The pilot light is a small flame that ignites the burners in your furnace to produce heat. It’s a crucial component that ensures your furnace functions correctly. When the pilot light is extinguished, it can prevent the furnace from producing any heat.
Why is the Pilot Light Important?
The pilot light serves several purposes:
- Ignites the main burner: The pilot light is responsible for lighting the main burner, which then ignites the gas or fuel to produce heat.
- Monitors gas pressure: The pilot light ensures that the gas pressure in the system is within a safe range, preventing accidents and malfunctions.
- Prevents backdrafting: The pilot light helps prevent backdrafting, which is when combustible gases from the furnace are pushed back into the home, creating a hazard.
Where to Find the Pilot Light on Your Furnace?
Locating the pilot light on your furnace can be a bit challenging, but we’re here to guide you through the process. The location of the pilot light varies depending on the type of furnace you have:
- Upflow furnace: For upflow furnaces, the pilot light is usually located on the left or right side of the furnace, about 2-3 inches from the floor.
- Horizontal furnace: For horizontal furnaces, the pilot light is often situated on the top or bottom of the furnace, about 2-3 inches from the side.
- Vertical furnace: For vertical furnaces, the pilot light is usually located on the side of the furnace, about 2-3 inches from the top.

- Look for a small door or panel: Many furnaces have a small door or panel that can be removed to access the pilot light.
- Use a flashlight: If the area is dark, use a flashlight to illuminate the space and help you see the pilot light.
Safety Precautions
Before attempting to locate the pilot light, make sure to:
- Turn off the gas supply: Turn off the gas supply to the furnace to prevent any accidents or injuries.
