Your furnace can maintain a comfortable temperature. This is as long as everything operates correctly. You might not even be aware of it running in the background. However, like other equipment, it is prone to fail at some point. 

Many times, a furnace issue is relatively simple to resolve. A skilled expert can rapidly fix the problem. As a homeowner, you may also be able to diagnose some issues on your own. Knowing some of the most typical issues with furnaces can help you sense when there is a problem. 

Your furnace doesn’t generate heat

The primary function of your furnace is to provide warm air. Therefore, its failure to generate heat is usually a reason for concern. However, it may not be a major problem in many cases. Here are the causes:

• The fan setting is on: The furnace may circulate air through the house. However, the air won’t get heated. 
• Not turning on or setting the thermostat to “heat.”
• Setting the thermostat’s temperature too low. 
• Dust and debris can obstruct the furnace’s airflow. This gives the impression that it is not producing any heat. 

The pilot light keeps going out

A thermocouple is a safety mechanism that senses the pilot light flame. This is necessary to maintain the burner’s gas supply and ensure safe operation. An unclean thermocouple may give false temperature readings. This may cut off the gas supply to the furnace. 

You can use a wire brush to clean the thermocouple if the pilot light on your furnace keeps going out. If cleaning is ineffective, seeking a professional diagnosis for thermocouples is essential. It may be necessary to replace the component.

Your furnace has stopped functioning

Imagine a scenario whereby your furnace began a cycle, but abruptly stopped before the room reached the desired temperature. As with other furnace issues, a furnace may stop working because:

• The circuit breaker was tripped
• The pilot light or ignition was not working properly
• The airflow was blocked, or a safety switch was triggered. 

Your best bet is to have a qualified expert inspect and troubleshoot your furnace if it has shut down and you cannot determine why.

Unusual sounds

Disturbing sounds like clunking, banging, and screeching are distinct signs of furnace problems. A scraping sound could be an indication of blower-bearing deterioration. On the other hand, a squeaking sound is typically a sign of a blower belt issue. 

Nevertheless, determining the reason for a clunking noise can be more difficult. This is because a furnace has several mechanical components that might break or loosen over time. It is best to turn off your furnace until a qualified expert does a comprehensive check. This is to avoid the possible dangers of fire or additional damage. 

FINAL WORDS

Regular furnace maintenance is important, regardless of the season. It is a safeguard to make sure your heating system runs smoothly when you need it most. A skilled specialist’s help is crucial for a precise diagnosis of your furnace problems.
