Over time, dust and debris can accumulate around the pilot light, causing it to burn inefficiently or even go out. To clean your furnace pilot light, start by shutting off the gas supply and waiting for the furnace to cool completely. Next, find the pilot light assembly—usually located near the gas valve—and gently brush away any dirt using a small, soft brush. You can use compressed air to dislodge stubborn particles but avoid using water or harsh chemicals, as they can damage sensitive components. Once clean, visually inspect the area for rust or corrosion, as these issues may require professional attention. Reignite the pilot light according to the manufacturer's instructions and observe its flame; it should burn blue and steady, indicating proper function.Tips 1:As a designer, creating a maintenance-friendly utility area around your furnace can greatly simplify routine tasks like pilot light cleaning.
