If your furnace suddenly stops working, it can be a frustrating and uncomfortable experience, especially during the colder months. Fortunately, there are steps you can take to troubleshoot and possibly resolve the issue before calling a professional. Here are some tips to help you get started.

Check the Thermostat

The first step in troubleshooting a non-functioning furnace is to check the thermostat. Ensure it is set to “heat” and adjust the temperature setting to five degrees higher than the current room temperature. You should hear the furnace kick on almost immediately if the thermostat is working correctly. If the display is blank, replace the batteries to see if that resolves the issue. A functioning thermostat is a quick fix, and ensuring it’s set correctly can often solve the problem.

Inspect the Circuit Breaker

If the thermostat appears to be in working order, the next step is to check the circuit breaker. Locate the breaker that controls your furnace, and determine if it has been tripped. If it has, reset it by turning it off and then back on. If the breaker trips again, this could signify an electrical problem that requires professional attention. Checking the circuit breaker is essential, as the furnace needs a constant power supply to operate.

Examine the Air Filters

Dirty or clogged air filters can severely impact the performance of your furnace, potentially causing it to stop working. If you haven’t changed your furnace’s air filters recently, it’s time to replace them. Regular maintenance of air filters is necessary to prevent such issues, and they should be replaced every three months, or more frequently if you have pets or allergies.

Verify the Pilot Light and Furnace Switch

For gas furnaces, the pilot light or ignition system is crucial for proper functioning. If the pilot light has gone out, follow the manufacturer’s instructions to reignite it. Ensure the gas valve is open, as a closed valve can prevent the furnace from operating. Additionally, check the furnace switch, usually located on the side or top of the furnace, ensuring that it is in the “on” position. A simple flip of the switch or reignition of the pilot light can sometimes resolve the issue.

Contact a Professional

If none of these troubleshooting steps resolve the issue, it may be time to contact a professional HVAC technician. All Aboard Services have the expertise to handle more complex problems, such as clogged tubes, corroded connections, or broken motors and belts. They can also provide valuable maintenance advice to keep your furnace running efficiently and extend its lifespan.
