When the temperature drops, your furnace keeps you warm and cozy. However, even the most well-maintained furnace can experience issues from time to time. Knowing the most frequent furnace issues might help you locate the source of the problem and get it fixed more quickly.

Faulty Flame Sensors Can Stop The Unit From Activating 

The combustion chamber's flame sensor informs the system's controls of whether the burner is active. It is essential to make sure the furnace runs efficiently, but it also helps keep the unit safe. If the flame sensor fails to detect a flame, it may turn off the flow of fuel to prevent a leak or spill.

The furnace turning on and off frequently after just a few seconds of use is one sign of a faulty flame sensor. If your unit is short cycling, it's important to contact a professional to have the flame sensor replaced. Replacing the sensor is a quick and relatively inexpensive repair that will prevent more significant performance and safety issues from arising.

Damaged Or Degraded Burners Can Be Unable To Produce Heat

When the burners are damaged, they cannot produce enough heat to warm the air in your home. The result is a furnace that is constantly running but still does not deliver enough heat. Burners can be repaired, but they may need to be replaced entirely if the damage is severe. A professional furnace technician can determine the extent of the damage and recommend the most appropriate solution.

Fuel Supply Disruptions Can Deprive The Unit Of Oil Or Gas

Whether it is oil or gas, a furnace needs fuel to operate. A fuel supply disruption is one of the most common issues a furnace can experience. These disruptions can occur for various reasons, including clogged fuel lines or a faulty fuel pump. A lack of fuel can cause your furnace to shut down. Attempting to fix the issue yourself can be dangerous due to the risk of causing a fuel leak. Emergency furnace repair services can quickly restore your unit's performance.

Sediments In The Combustion Chamber Can Decrease Efficiency And Performance

The combustion chamber is where the fuel and air mix to produce heat in your furnace. Over time, sediments and debris can accumulate in the combustion chamber, which reduces its efficiency and performance. When the combustion chamber is not working correctly, the furnace may produce less heat and cost more to operate. A professional furnace technician can clean the combustion chamber and remove any sediment buildup. By having your combustion chamber cleaned annually, you can catch these issues early and avoid costly energy bills.
