Furnace Not Igniting? – Find Out What’s Wrong And You Can Fix It

Though a heating system can fail at any time of year, most residents do not notice any furnace problems until they switch it on in the winter, only to find out that it’s not igniting. If this happens to you, you can do a few things to get your system back up and running. However, if you think you cannot perform the troubleshooting yourself, it is better to call experts for heating service in Encinitas for a repair. In addition, to steer clear of such issues, you must perform routine maintenance of your furnace. 

Reasons for a furnace not igniting

Mentioned hereunder are some of the common reasons your heating system is not igniting. 

  • Inaccurate thermostat adjustment
    Many homeowners hesitate to reset their thermostat setting back to ‘warm’ or ‘heating’ after a light fall, and they even fail to inform their thermostat what kind of heating or cooling they want in their house. Inspect your thermostat first, then move on to more complicated issues. Check that the thermostat remains set to heating and that the temperature is high enough to turn on the heater. If your heating system remains at a too low temperature, the furnace will not turn on in the first place.

  • Clogged air filter
    Furnaces require a sufficient amount of air to function accurately. If you haven’t replaced your air filter in a long time, it could be why your furnace is not lighting. To replace or change your air filter, remove the existing filter and open the steel grate that houses it. If the filter is visibly dusty, it is time to replace your air filter. If you have pets or live in a polluted region, you may need to clean it more frequently. Some air filter providers promote that their filters do not need to be changed often. However, whether you do or do not need to replace your filter is defined more by your home’s climate than anything else.

  • Failed electrical system or a blown fuse
    A flipped circuit breaker or the blown furnace fuse could be the underlying cause of your furnace not lighting correctly. If this is the case, you may not be able to tell if you have an old model thermostat. Though it may appear overly straightforward, rule this one out before moving on. Next, examine your electrical panel to find if any circuit breakers have tripped. If so, reactivate them. However, if it trips again right away, it indicates a flaw in your circuit. If this is the case, do not turn it back on and call an expert in heating service in Encinitas immediately. In addition, if your place has a fuse board, you should cut off the power to the entire property. Pull off the main fuse block to accomplish this. It is better to use an amp meter for extra security to ensure the power remains cut.
