How to Check if Furnace is Working
Furnaces are essential for keeping our homes warm during the cold winter months. However, it can be frustrating when you realize that your furnace is not working properly. Before calling a professional, it’s important to check a few things to determine if your furnace is indeed functioning. In this article, we will guide you through the steps to check if your furnace is working and what to do if it’s not.
Step 1: Check the Power Supply
The first thing you should do is ensure that your furnace is receiving power. Check the circuit breaker to see if the furnace’s circuit is turned on. If the circuit is off, flip the switch to the “on” position. Additionally, make sure that the furnace’s power switch is turned on. If the power supply is fine, but the furnace still doesn’t work, proceed to the next step.
Step 2: Inspect the Thermostat
Next, inspect your thermostat to make sure it’s set to the correct temperature and the fan is set to “auto.” If the thermostat is set to “on” and the temperature is lower than the set point, the furnace should turn on. If it doesn’t, there might be an issue with the thermostat itself.
Step 3: Check the Ignition System
Gas furnaces have an ignition system that lights the burners. If the ignition system is not working, the furnace will not heat your home. To check the ignition system, locate the pilot light and ensure it’s lit. If the pilot light is out, you may need to relight it. If you’re not comfortable doing this yourself, it’s best to call a professional.
Step 4: Inspect the Burners
If the pilot light is lit, the next step is to check the burners. Look for any signs of dirt, debris, or soot buildup on the burners. If the burners are dirty, clean them with a damp cloth. If the burners are clean and the pilot light is still out, there may be an issue with the gas valve or the thermocouple.
Step 5: Listen for Sounds
When your furnace is working properly, you should hear a series of clicks and hums as the system starts up. If you don’t hear these sounds, there may be an issue with the blower motor or the control board.
Step 6: Check the Air Vents
Finally, check the air vents in your home to ensure they are not blocked. If the vents are blocked, the heat may not be distributed evenly throughout your home.
Conclusion
If you’ve followed these steps and your furnace is still not working, it’s best to call a professional to diagnose and repair the issue. Regular maintenance and proper care can help prevent future problems with your furnace. Remember, safety always comes first, so if you’re ever in doubt, don’t hesitate to seek professional help.
