Introduction 🌡️
Is your furnace pilot light giving you trouble? A malfunctioning pilot light can leave you without heat, especially during the colder months. In this blog, ANG Heating and Air Conditioning will guide you through common pilot light issues, their causes, and how to address them effectively.
‍
What Is a Pilot Light? 🌟
A pilot light is a small, continuously burning flame that serves as the ignition source for the main gas burner in your furnace. When your thermostat signals the furnace to turn on, the pilot light ignites the gas burners to produce heat. However, if the pilot light goes out, your furnace won’t be able to generate heat, leaving your home cold and uncomfortable.
‍
Common Causes of Pilot Light Issues 🔍
- Faulty Thermocouple: The thermocouple is a safety device that detects whether the pilot light is lit. If it’s faulty, it can shut off the gas supply, causing the pilot light to go out. This can be due to wear and tear or a loose connection.
- Dirty Pilot Light Orifice: Dirt and debris can clog the pilot light orifice, preventing the flame from staying lit. Over time, dust and grime build up, which can obstruct the gas flow and extinguish the pilot light. Regular cleaning can help prevent this issue and ensure a steady flame.
- Wind or Drafts: Strong winds or drafts can blow out the pilot light, especially if your furnace is located in a drafty area. Ensuring that the area around your furnace is well-protected from drafts can help keep the pilot light burning.
- Gas Supply Issues: Problems with the gas supply, such as low pressure or a closed valve, can prevent the pilot light from staying lit. It’s essential to ensure that the gas supply to your furnace is steady and uninterrupted.

How to Relight a Pilot Light 🔥
- Turn Off the Furnace: Before attempting to relight the pilot light, turn off the furnace and wait a few minutes for the gas to dissipate. This is an important safety step to avoid any potential gas buildup.
- Locate the Pilot Light: Refer to your furnace’s owner’s manual to find the pilot light. It’s usually located near the bottom of the furnace behind a removable access panel. Familiarizing yourself with the exact location can make the process easier and safer.
- Turn the Pilot Light On: Turn the pilot light control to the “On” position and hold it down. Use a long match or lighter to ignite the pilot light. This step requires patience and steady hands to ensure the flame catches properly.
- Keep the Control Held Down: Keep holding the control down for about 30 seconds to ensure the pilot light stays lit. Then, release the control and check if the pilot light remains on. This holding period allows the thermocouple to heat up and confirm the presence of the flame.
- Replace the Access Panel: Once the pilot light is lit, replace the access panel and turn the furnace back on. Ensuring that the panel is securely in place helps maintain safety and efficiency.
