Gas furnaces are an essential part of many homes, providing warmth during the cold winter months. However, to ensure that your furnace functions efficiently, you must know how to light the pilot light. The pilot light is a small flame that ignites the burners in the furnace, which then warms your home. In this article, we will provide you with a step-by-step guide on how to light the pilot on a gas furnace.
Preparing for Lighting the Pilot
Before you begin, it is essential to understand the gas furnace and its parts. Familiarize yourself with the location of the pilot light and the gas supply valve. In most cases, the pilot light is located near the bottom of the furnace, and the gas supply valve is located near the gas line that leads to the furnace.
To light the pilot, you must first turn off the gas supply valve. This valve is typically located near the gas line that leads to the furnace. Turn the valve to the “off” position and wait for a few minutes before continuing. This step is crucial because it allows any gas that may have accumulated in the furnace to dissipate.
Next, identify the pilot light. The pilot light is typically a small flame that stays lit at all times. It is usually located near the burners and may require you to remove a small cover to access it.
Once you have identified the pilot light and turned off the gas supply valve, you are ready to light the pilot.
Lighting the Pilot
There are two ways to light the pilot on a gas furnace: using an igniter or a matchstick. If your furnace has an igniter, follow these steps:
- Locate the igniter button near the pilot light.
- Hold down the button and wait for the igniter to spark.
- Once the pilot light ignites, continue to hold down the button for about 30 seconds to allow the thermocouple to heat up and keep the pilot light lit.
- Release the button and check to ensure that the pilot light stays lit.
If your furnace does not have an igniter, you must use a matchstick to light the pilot. Follow these steps:
- Hold a matchstick or lighter near the pilot light.
- Turn the gas supply valve to the “on” position.
- Light the matchstick and bring it close to the pilot light.
- Once the pilot light ignites, continue to hold the matchstick near the light for about 30 seconds to allow the thermocouple to heat up and keep the pilot light lit.
- Remove the matchstick and check to ensure that the pilot light stays lit.
While lighting the pilot, it is critical to take safety precautions. Wear protective gloves to prevent burns and keep flammable materials away from the furnace. If you smell gas or notice any signs of a gas leak, turn off the gas supply valve immediately and contact a professional.
Restarting the Furnace
After lighting the pilot and ensuring that it stays lit, it is time to restart the furnace. Begin by turning on the gas supply valve and waiting a few minutes for the burners to ignite. Once the burners have ignited, set the thermostat to the desired temperature, and the furnace should begin heating your home.
If the furnace does not restart or you notice any issues, turn off the furnace and contact a professional for assistance. It is crucial to ensure that your furnace is functioning correctly to prevent any safety hazards and ensure that your home is adequately heated.
Sometimes, despite your best efforts, the pilot light may not stay lit. This can be due to a variety of reasons, including a dirty pilot orifice, a faulty thermocouple, or a malfunctioning gas valve. If you find that the pilot light won’t stay lit, there are a few things you can try before calling in a professional.
First, ensure that the gas supply valve is fully open. If it is partially closed, it can affect the pilot light’s performance. Next, check the pilot orifice for any dirt or debris that may be blocking it. If you find any, clean it with compressed air or a wire brush.
If the pilot light still won’t stay lit, the thermocouple may be faulty. The thermocouple is a safety device that detects the pilot light’s presence and signals the gas valve to open. If it is faulty, it can prevent the gas valve from opening, causing the pilot light to go out. In this case, it may be necessary to replace the thermocouple.
Finally, if none of the above solutions work, the gas valve may be faulty, and it’s time to call in a professional.
In conclusion, knowing how to light the pilot on a gas furnace is an essential skill for homeowners. By following the steps outlined in this guide, you can safely and effectively light the pilot on your furnace, ensuring that it functions efficiently throughout the winter months.
Regular maintenance, including cleaning the pilot orifice, replacing the thermocouple, and checking the gas supply valve, can prevent issues from arising and prolong the furnace’s lifespan.
Remember to always prioritize safety when working with gas appliances. If you are unsure about any of the steps outlined in this guide or encounter any issues, seek professional help immediately.
