Step-by-Step Guide: Relighting the Pilot Light on Your Gas HVAC System at Home
TRY THIS ONLY AT YOUR OWN RISK!
Understanding the Pilot Light
Let's start with the basics. The pilot light is a small flame that continuously burns and is essential for lighting the main burner of your gas HVAC system. If the pilot light goes out, the system stops working, leaving your home chilly.
Common reasons for a pilot light going out include drafts, a clogged pilot assembly, or even a faulty thermocouple. In fact, nearly 30% of pilot light issues stem from debris accumulation, highlighting the importance of regular maintenance.
Safety Precautions
Safety should always come first when dealing with gas appliances. Here are some key safety steps to follow:
Turn Off the Gas Supply: Locate the gas valve and turn it to the "off" position to prevent gas leakage.
Ventilate the Area: Open windows or doors to improve air circulation, reducing the risk of gas accumulation.
Use a Flashlight: Instead of matches or candles, use a flashlight to illuminate the area. This minimizes fire hazards if gas is present.
Wear Safety Gear: Consider wearing gloves and goggles to protect against accidental injuries while you work.
With safety covered, let’s move on to relighting the pilot light.
Step 1: Locate the Pilot Light Assembly
The first task is to find the pilot light assembly, typically situated near the base of the furnace.
Using your flashlight, identify the pilot light tube and a small access panel, which may be secured with screws or clips. Remove the panel carefully to access your pilot light.
Step 2: Clean the Pilot Light Area
Dust and debris can hinder the pilot light from igniting efficiently. Before lighting, clean the area around the pilot light assembly.
Use a soft brush to gently remove any grime. If the pilot light tube is clogged, a small pin or needle can be effective for cleaning. Take your time to ensure that everything is completely clean and unobstructed.
Step 3: Prepare to Relight the Pilot Light
Now you are ready to relight the pilot light. Follow these steps carefully:
Set the Thermostat: Adjust the thermostat to the lowest setting to avoid accidentally triggering the HVAC system when relighting.
Turn the Gas Valve On: Switch the gas valve back to the “On” position.
Set the Control Knob: Rotate the control knob on your gas valve to the “Pilot” position.
Press the Reset Button: If your system has a reset button, hold it down while getting ready to light the pilot. This step allows gas to flow to the pilot assembly.
Step 4: Light the Pilot
You are now set to light the pilot. Depending on your system, there are two common methods:
Lighter Method: Use a long-reach lighter. While pressing the reset button, bring the flame close to the pilot light.
Match Method: If you prefer matches, hold one near the pilot light assembly as you press the reset button.
Once lit, the flame should burn steadily. You can release the reset button once the pilot light is securely ignited.

Step 5: Check the Flame and Reassemble
After lighting the pilot light, observe it for about a minute. A healthy flame should be blue and steady; if it appears yellow or flickers, there may be issues with airflow or gas supply.
When you verify that the pilot light is stable, replace the access panel and secure it properly.
Summary and Next Steps
Relighting the pilot light on your gas HVAC system is a manageable task that can spare you discomfort during cold days and nights. By following this guide, you can take control of your home's heating situation and ensure warmth when you need it most.
If, after following these instructions, your pilot light continues to extinguish, or if you notice any unusual odors or sounds, it is advisable to consult a professional technician. Additionally, regular maintenance checks of your HVAC system can prevent pilot light issues and keep your heating system functioning efficiently.
Stay warm and safe!
