A gas furnace is an efficient appliance that can keep the entire home warm even when the outside temperature plummets. This device has a variety of components that can potentially malfunction, and understanding some of the most common parts will help you secure prompt heating system repair and avoid a full breakdown. Below is more information about several common components to help you spot issues.

What Parts Are Inside a Gas Furnace?

1. Blower

The furnace has an internal chamber that holds the blower and blower motor. The blower motor is a large device that powers the blower, which is a fan that pushes warm air through the ductwork to heat the home. If one of these components malfunctions, the furnace cannot warm the home effectively, which means you may notice inadequate airflow from the vents. This also often causes the heating system to run for longer periods, which can result in increased utility bills. If a part breaks inside the motor, you may hear clanking, squeaking, or rattling noises when the device turns on.

2. Burners

The burners pull gas from the supply line, allowing the pilot light to ignite it, resulting in fire that the furnace uses to heat the home. When working properly, the burners should produce a consistent, regulated flame, which sends warmth to the heat exchanger. The flame should be a steady blue color when the gas is flowing properly. If it's yellow, debris may be blocking the orifices, preventing consistent burning. Other signs of problems include slow ignition, a booming noise upon turning on, and failure to turn on at all.

3. Heat Exchanger

Heat from combustion enters the heat exchanger, where it is absorbed by the device's walls and distributed throughout the house by the blower. As the gaseous byproducts cool, they are vented through a pipe so that they don't accumulate in the home. This prevents toxic carbon monoxide from leaking into the living area. If you notice soot buildup near the burners, the heat exchanger may be cracked, which allows debris and gas to leak from it. Make sure you have a carbon monoxide detector installed near the furnace, and change the batteries regularly. This will alert you to potential issues, protecting your home and family.
