To clean a dirty or blocked pilot orifice, we need to turn off the gas supply and let the furnace cool down. Then, using a small brush or compressed air, gently clean the orifice to remove any debris or buildup. It’s important to be cautious and avoid damaging the delicate parts. Once cleaned, we can carefully relight the pilot light and monitor it for any issues. Regular maintenance is key to preventing further problems with the pilot light.
