October 12, 2023

A Step-by-Step Guide

Is your furnace not producing heat, leaving you shivering in the cold Utah winters? Before you call in the professionals at Craig’s Services in Bountiful, UT, there’s a simple DIY solution you can try: lighting the pilot light. It’s a common issue that many homeowners face, and with our step-by-step guide, you’ll be cozy and warm in no time.

What is a Pilot Light?

First, let’s understand what a pilot light is. In older furnace models, the pilot light is a small, continuously burning flame that ignites the main burner when your thermostat signals a need for heat. If your pilot light has gone out, it needs to be relit to restore proper heating function.

Safety First

Before we dive into the process, remember to prioritize safety. Turn off the thermostat and shut off the gas supply to the furnace. Wait at least five minutes to allow any residual gas to dissipate. Safety goggles and gloves are recommended to protect your eyes and hands.

Equipment You’ll Need

To light the pilot light, you’ll need a few essential tools:

  • Long-Handled Lighter: This helps you ignite the pilot without putting your hand near the flame.
  • Flashlight: You’ll need it to see inside the furnace clearly.

Step-by-Step Guide

Now, let’s get into the nitty-gritty of lighting your furnace’s pilot light:

Step 1: Locate the Pilot Light

Open the furnace access panel. You should see a small gas control knob with three settings: “Off,” “On,” and “Pilot.” Turn the knob to “Off.”

Step 2: Find the Pilot Light Assembly

Use your flashlight to locate the pilot light assembly. It’s usually located near the burner, and you’ll see a small tube leading to a burner assembly.

Step 3: Prepare to Light

Hold the gas control knob in the “Pilot” position and press the knob down. This will allow gas to flow to the pilot light.

Step 4: Ignite the Pilot Light

Using your long-handled lighter, place the flame near the pilot opening and carefully light the pilot light. Continue holding the control knob down for about 30 seconds.

Step 5: Release the Control Knob

After 30 seconds, release the control knob. If the pilot light stays lit, you’re in business. If it goes out, repeat steps 3 and 4.

Step 6: Turn on the Furnace

Once the pilot light is burning steadily, turn the gas control knob to the “On” position and adjust your thermostat to your desired temperature. Your furnace should now start producing heat.
