Furnaces are essential to keeping our homes warm and comfortable during the cold winter months. But like any piece of machinery, furnaces can have their problems. Knowing what the most common furnace problems are can help you troubleshoot and fix any issues that may arise when it comes to your furnace. The most common problem with furnaces is a lack of maintenance, which can result in clogged filters, dirty burners, and other parts that need to be serviced or replaced.
Regular maintenance will help keep your furnace running efficiently and reduce the chance of a breakdown. Another common issue with furnaces is a pilot light that won’t stay lit or won‘t ignite at all. If this happens, it could be due to several different causes such as faulty wiring, an obstruction in the burner chamber, or a malfunctioning thermocouple. If your pilot light doesn’t stay lit for more than 10 seconds after being lit, you should call an HVAC technician to repair it properly. Furnace blower motors can also experience problems from time to time due to wear and tear or improper installation by an inexperienced HVAC technician. One of the most common blower motor issues is when it runs continuously even when there’s no demand for heat from the thermostat—this could point towards a problem with the thermostat itself or even blocked vents in your home that are preventing proper airflow through your heating system.
Lastly, furnace igniters may stop working because they become weak over time due to use or normal wear–and–tear—sometimes they just need cleaning but if they start sparking sporadically then they should be replaced as soon as possible before any further damage occurs in order to avoid more costly repairs down the line. Overall, keeping up with regular maintenance on your furnace will help prevent many of these problems from occurring in the first place—but if something does happen then knowing what some of the most common furnace issues are will definitely come in handy!
