What are the parts of a furnace called?
The main parts of your furnace are the control system (thermostat and electrical controls), gas valve, burners, heat exchanger, blower, and duct and ventilation system. When your furnace creates heat, combustion gases are vented out of your home via a flue pipe.
What part of the furnace is the blower?
The blower motor is usually located near the base of the furnace in the blower chamber, and it resembles a hamster wheel. It contains a fan (or blower) that sends an even current of air through the appliance. Air moves past the heat exchanger and into the supply plenum.

Perhaps there is a wiring issue causing the blower to stop working. The motor might have a problem and requires service.
What is the top part of a furnace called?
This photo shows you how the furnace is divided into two cabinets: the burner cabinet (top) and the blower cabinet (bottom). This is reversed in a down-flow system where the ductwork is located below the unit. A horizontal unit will be set up the same as an up-flow most often and just laid onto its’ side.
What are the components of a forced air furnace?
Parts of a Forced-air Heating System
- Heat exchanger.
- Blower.
- Return ducts (sucks in cool air)
- Supply ducts (pushes warm air into different rooms)
- Air plenum.
- Fan limit switch.
Are the furnace fan and blower the same thing?
Most central heating systems in existence today are forced air systems and therefore require air to be moved in some way. A furnace fan, also known as a furnace blower, is one of the easiest ways to accomplish this. Most furnace fans come with a motor that is one horsepower or less.

After noting the motor’s wire color connections to the furnace itself, you can cut or remove the wires from their connection point.
What are the parts of your furnace?
Gas valve: Regulates the pressure of gas entering the furnace from an outside source, either a tank of LPG or a natural gas supply line. Air filter: A membrane designed to keep dust and debris from entering the furnace with the cool air. Transformer: These supply electricity to the furnace and regulate it down to the correct voltage.
What are the parts of a blower motor?
