Furnace Repair – How to Troubleshoot a Furnace Problem
If you have noticed that your furnace is running too loudly or constantly why us? it might be time for a repair. Usually, the light on the furnace should be green. The problem may be in the blower motor, thermostat, run capacitor, furnace control board, or transformer. The blower is located between the supply ducts and the furnace, and it sends cool air into the heat exchanger. The air is then heated and sent through the supply ducts. However, if you notice that the blower motor is constantly running, your furnace is likely in need of repair.
A dirty or worn air filter can also be a cause of your furnace cycling. If this happens, try to clean it using a fine emery cloth. Afterward, you can slip it back into its bracket. Another common problem can be with the ignition system. This component is connected to the blower motor and needs to be checked by a professional.
If you’re unsure of how to troubleshoot a problem, consult the owner’s manual to learn more about this important part of the furnace. Make sure to turn off the power before attempting to repair the furnace. If you’re unable to get the furnace to run, check the ignition switch first. If this doesn’t work, you might need to replace the igniter. Otherwise, call a professional for a furnace repair.
