As a homeowner, it’s important that you’re able to perform some basic repair work on your furnace. One of the most basic fixes that you should know how to perform is relighting your furnace’s pilot light. If you’re currently unaware of how to do this, we’re going to share with you a step-by-step guide below.

Why Does My Furnace Have a Pilot Light?

If you’re not overly familiar with how your furnace works, it’s likely that you don’t understand why it has a pilot light in the first place. The pilot light is an essential furnace component that works to ignite the burners inside of your furnace. Once these burners are ignited, they can create heat for your home. Whenever your pilot light goes out, it’s not able to ignite the burners. Therefore, your home will be without heat until you can get that pilot light relit.

Where Is the Pilot Light?

The pilot light is usually located near the bottom of the furnace unit. You’ll be able to locate a small window with a burner where the flame stays lit. On some furnaces, you may need to remove an access panel to locate this assembly. If you can’t find it, it’s advisable to consult your owner’s manual or a local HVAC pro.

Near the pilot light burner, you’ll need to locate the reset button and a knob. The reset button is typically a bright red or yellow color. It may be shaped as a square or a circle, depending on the specific furnace brand that you have.

The knob should be in the surrounding area. It will have three different modes, including off, pilot, and on. Off mode will kill all the fuel flow to the actual pilot light burner. Pilot mode will allow fuel to flow to the burner but will restrict the furnace from turning on. Lastly, on mode allows the furnace to turn on to heat your home. It’s important to understand the differences between these modes when you’re getting ready to relight your pilot light so that you can do it successfully.

Stop the Fuel Flow and Wait

Once you locate the pilot light assembly, you want to turn the knob to the off position. This will stop the flow of fuel to the pilot light. It’s best to give it a few minutes in this position so that any excess fuel near the pilot light can dissipate into the air. You don’t want to try to immediately relight the pilot light since the gas that is near the pilot light will ignite into a large flame. This can catch other objects in the room on fire or result in a burn injury for you.

Relighting the Pilot Light

While you are waiting for the excess gas to dissipate, you’ll want to grab a lighting mechanism. You should avoid using a cigarette lighter or a small matchstick as your fingers will be too close to the flame and will likely get burnt. You should opt for a long matchstick or a grill-style lighter.

Once you’re ready, go ahead and turn the knob to the pilot position. You want to hold down the reset button while you light the pilot burner. Make sure that you continue to hold down the reset button until the pilot light becomes a solid blue flame. Next, you want to let go of the reset button and turn the knob from the pilot position to the on position. Your furnace should automatically kick on as soon as you go into that on position.

Examine Your Furnace

Now, since your pilot light is lit, it’s time to examine your furnace to ensure that it stays that way. You want to give it a solid minute to ensure that a draft does not blow out the flame and to make sure that the flame doesn’t change colors. If you experience either of these problems, it’s advisable to contact an HVAC professional to handle your furnace problem from here.
