Furnace Cut-Away
This is what your furnace looks like on the inside.
![Furnace Heat Exchanger Furnace Heat Exchanger](https://www.allqualityair.com/i/furnace-parts/furnace-heat-exchanger.jpg)
Heat Exchanger
This is what allows the heat from the fire to be transferred to the air circulating in your home.
![Furnace Inducer Motor Furnace Inducer Motor](https://www.allqualityair.com/i/furnace-parts/furnace-blower-motor.jpg)
Inducer Motor
This carries the By-Products of combustion (Carbon monoxide, Hydrocarbons, etc.) out to the outside of your home.
![Blower Wheel Furnace Blower Wheel](https://www.allqualityair.com/i/furnace-parts/furnace-blower-wheel.jpg)
Furnace Blower Wheel
Attached to the blower motor, this circulates the air in your home.
![Furnace Hot Surface Igniter Furnace Hot Surface Igniter](https://www.allqualityair.com/i/furnace-parts/furnace-hot-surface-igniter.jpg)
Furnace Hot Surface Igniter
This eliminates the “Standing Pilot” which saves money and is what ignites the gas on a call for heat.
![Furnace Flame Sensor Furnace Flame Sensor](https://www.allqualityair.com/i/furnace-parts/furnace-flame-sensor.jpg)
Furnace Flame Sensor
Once the gas is ignited the senses or “Proofs” that the ignition of gas was successful.
![Furnace Relay Furnace Relay](https://www.allqualityair.com/i/furnace-parts/furnace-relay.jpg)
Furnace Relay
This temperature sensing relay is often used as a “High Limit” safety preventing a runaway furnace.
![Furnace Blower Motor Furnace Blower Motor](https://www.allqualityair.com/i/furnace-parts/furnace-blower-motor.jpg)
Furnace Blower Motor
This motor drives the blower wheel which in turn circulates the air in your home.
![Furnace Gas Valve Furnace Gas Valve](https://www.allqualityair.com/i/furnace-parts/furnace-gas-valve.jpg)
Furnace Gas Valve
This controls the flow of natural gas (or LP gas) into the burners during operation.
![Furnace Condensate Pump Furnace Condensate Pump](https://www.allqualityair.com/i/furnace-parts/furnace-condensate-pump.jpg)
Furnace Condensate Pump
During A/C operation, water is produced as a by-product of cooling (dehumidification). The water is collected in the condensate pump and in turn pumped outside.
![Furnace Transformer Furnace Transformer](https://www.allqualityair.com/i/furnace-parts/furnace-transformer.jpg)
Furnace Transformer
This provides the “low-voltage” control that runs the system. The low voltage is 24 volts and is safer than the normal 120/240 volts used to power the motors and compressor.
![Furnace Burners Furnace Burners](https://www.allqualityair.com/i/furnace-parts/furnace-burners.jpg)
Furnace Burners
This is where the fuel-air mixture is ignited and burned, supplying heat to your home.
![Furnace Pressure Switch Furnace Pressure Switch](https://www.allqualityair.com/i/furnace-parts/furnace-pressure-switch.jpg)
Furnace Pressure Switch
This safety device “proofs” the induced draft fan operation.
![Furnace Control Board Furnace Control Board](https://www.allqualityair.com/i/furnace-parts/furnace-control-board.jpg)
Furnace Control Board
This is the “brain” of the indoor system which controls the entire sequence of operation while monitoring the safety devices.
