It\u2019s getting pretty late in the winter, but it isn\u2019t spring yet. It\u2019s not quite time to be done with our heating systems. We\u2019ll still need them a bit longer! So if your furnace\u2019s burners aren\u2019t lighting, you\u2019ll need to get that fixed right away. What can cause this? Here are some of the possibilities.<\/p>\n\n\n\n\n\n\n\n

Pilot Problems<\/h2>\n\n\n\n

Today\u2019s gas furnaces don\u2019t use pilot lights, but if you have an older furnace, you might still have one. This needs to stay lit at all times, and if it goes out, it needs to be relit. Make sure to follow the directions in your owner\u2019s manual carefully so that you can relight the pilot safely. If you can\u2019t manage it, or the pilot light keeps going out after you relight it, you\u2019ll need furnace repair in Marana, AZ<\/a>.<\/p>\n\n\n\n

Electronic Ignition Problems<\/h2>\n\n\n\n

The modern alternative to the pilot light is the electronic ignition system, which creates a spark to light the gas rather than keeping a flame standing at all times. If this system malfunctions or fails, the burners won\u2019t light. A heating repair technician can determine exactly what went wrong and repair it, or replace the igniter if necessary.<\/p>\n\n\n\n

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

The flame sensor does a complex and important job. A small amount of gas is used to light a flame. Then, more gas is released once the flame is properly lit. Without a flame, it would be dangerous to release more gas\u2014it would just be a gas leak\u2014so the flame sensor is necessary for determining that it\u2019s safe to release enough gas to light the burners.<\/p>\n\n\n\n

Despite how critical this job is, the flame sensor itself is an extremely simple component. It\u2019s just a metal rod! How does that detect a flame? It uses itself, and the flame, to complete an electrical circuit which allows the gas to flow. If there\u2019s no flame, the circuit is incomplete. <\/p>\n\n\n\n

But because of all the combustion it\u2019s exposed to, a layer of carbon can build up over the sensor. Carbon is a great insulator and will prevent the circuit from being completed even when there is a flame! This will stop the burners from being lit. A technician can disassemble this circuit and clean the sensor so it will work properly again.<\/p>\n\n\n\n

Burner Problems<\/h2>\n\n\n\n

It\u2019s possible that something is truly wrong with the burners that requires repair or replacement of one or more of these components. It\u2019s also possible that, like the flame sensor mentioned above, the burners are simply dirty. An accumulation of carbon may need to be removed to allow them to light.<\/p>\n\n\n\n

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

In order for the gas to flow, the gas valve needs to be able to open and close smoothly. It usually does this job perfectly, but on occasion, it can get stuck in one position. If this is your problem, you might be able to hear clicking sounds coming from your furnace. <\/p>\n\n\n\n

Thermostat Problems<\/h2>\n\n\n\n

Finally, your burners won\u2019t come on if the thermostat doesn\u2019t tell them to! This could happen if you\u2019ve accidentally nudged a switch into the \u201cfan only\u201d position, so check that your thermostat\u2019s settings are correct before calling for repairs. But it can also be due to loose or disconnected wiring or a miscalibration, which would need professional attention.<\/p>\n\n\n\n

Whatever the cause, prompt repair can get your burners lit and your home toasty again so you can stay warm for the rest of the winter.<\/p>\n\n\n\n
