Ah, the comforting whoosh and hum of a running furnace. It\u2019s a cozy reminder that your heat is working and your home is being kept nice and warm. But it\u2019s also one of those things you don\u2019t pay much attention to. It\u2019s the absence of that sound that you really notice. What could be going wrong?<\/p>\n\n\n\n

If your furnace is trying to start but not getting running, a variety of things could be occurring. Here are the most likely culprits if your furnace\u2019s burners aren\u2019t coming on. Chances are, it\u2019s straightforward for a qualified professional to fix.<\/p>\n\n\n\n\n\n\n\n

The Pilot<\/h2>\n\n\n\n

Pilot lights used to be the only way furnace burners were lit, but you\u2019ll only have one now if your furnace is older. It needs to be lit at all times, so if it\u2019s out, find your furnace\u2019s owner\u2019s manual and follow the instructions to re-light it. If you can\u2019t, or if you do but it keeps going out again, you\u2019ll need heating repair in Evanston, IL<\/a> to clean or repair the pilot assembly.<\/p>\n\n\n\n

The Electronic Ignition System<\/h2>\n\n\n\n

This is how newer furnaces light: an electronic igniter makes a spark. These ignition systems often don\u2019t last as long as the furnace itself and will require replacement at some point during your furnace\u2019s life. Like all of the repairs we mention here, this must be done by a qualified professional, both for your safety and to keep from voiding your warranty.<\/p>\n\n\n\n

The Flame Sensor<\/h2>\n\n\n\n

This component is a safety mechanism. It determines whether there\u2019s a flame, and only allows gas to be released if the flame is present. If you do have a flame, but the flame sensor isn\u2019t allowing gas to flow, it may simply be too dirty to detect that the flame is there. A technician can disassemble and clean it.<\/p>\n\n\n\n

The Gas Valve<\/h2>\n\n\n\n

This is the valve that the flame sensor allows to open once the flame is detected. If it\u2019s stuck shut, no gas will flow, and the furnace will shut down without the burners lighting. Do keep in mind that, for safety, gas lines must only be handled by people with the proper licensing. There may even be legal requirements in your area about this. So don\u2019t try to fix it yourself, get help from a qualified professional.<\/p>\n\n\n\n

The Burners<\/h2>\n\n\n\n

If none of these other components are preventing your burners from lighting, it\u2019s probably the burners themselves that are the problem. While your furnace\u2019s burners are unlikely to actually break or fail, they\u2019re likely to become dirty. Your heating technician will have to disassemble them in order to carefully clean away the carbon or grime that is coating them.\u00a0<\/p>\n\n\n\n

Preventing the Problem in the Future<\/h2>\n\n\n\n

Once you\u2019ve gotten your heating issue resolved, you\u2019ll be glad to know that it can probably be avoided in the future. How can you keep your burners burning without issues caused by dirty or malfunctioning components? Annual maintenance! This involves cleaning all components and testing to make sure everything works properly. The vast majority of repairs can be avoided by having this done every year.<\/p>\n\n\n\n
