Troubleshooting Tips For A Malfunctioning Furnace

It may happen that during the winter season, your furnace may unexpectedly stop working. Even after regular maintenance and service jobs, your furnace may stop working for no apparent reason. However, instead of contacting a professional for furnace service in LaSalle every time, you can try some troubleshooting methods.

Of course, you can call a professional once you detect a problem with your furnace. But the real problem causing your furnace to malfunction may be minor, and you may not need to call a professional for that. You may end up paying big bills for a simple problem. Here are some simple tips you should try to save your money and time:

  • Fix the Circuit Breaker

If your furnace is not starting even though you have plugged and unplugged it from the socket, you should check its circuit breaker. A voltage difference may have caused the circuit breaker to flip down. Check the circuit breaker panel and locate the furnace’s breaker.

  • Check the Pilot Light

The pilot light is responsible for lighting the fire in the furnace to generate heat. However, if the pilot light is not lighting up, check the gas valve to ensure that the fuel enters the furnace. If the gas valve is on, the pilot light may be malfunctioning, and you may have to search for an HVAC repair near me.

  • Replace the Safety Switch

The safety switch flips when the front panel gets detached, and the furnace will stop working. You can replace the safety switch yourself or search for an HVAC installation company near me to do it for you.

  • Check the Flame

The flame color in a furnace should be blue. A flame with any other color indicates that the burner is dirty and the furnace will not generate enough heat. Clean the burner with a vacuum or other tools and reinsert it to check the flame color.

  • Adjust the Limit Switch

The limit switch ensures that the air that goes into your home is at the right temperature. A malfunctioning limit switch will not detect the right temperature of the air, and the system will malfunction. You can easily unscrew and adjust the limit switch on your furnace. But if you see that your furnace is still not working, you should call for professional help to fix the limit switch.

  • Clean the Flame Sensor

The flame sensor ensures that the gas does not leak during the combustion process and burns properly. A malfunctioning flame sensor will not help the combustion process, and the furnace will not work properly. Clean the flame sensor with a towel or sponge after removing it.

  • Regularly Clean the Filters

Filters maintain indoor air quality and create a smooth path for airflow. Dirty filters will force the system to work for more hours, leading to more wear and tear and eventual breakdown of the system. Avoid this problem by cleaning or replacing your furnace filters regularly.
