What is the brain of a furnace?
Circuit board The circuit board is the brain of most modern furnaces. It controls many sophisticated processes and continuously monitors the furnace’s operation.
Which 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.
What is the heat exchanger on a furnace?
What is a Heat Exchanger? The heat exchanger in a furnace separates the combustion process from your breathing air. It is a combination metal chamber and passageway that starts at the burner assembly and ends approximately where the chimney vent connects to the furnace.
What is the most important part of a furnace?
heat exchanger
The heat exchanger is the most important part of your heater or furnace, because it’s the tool that heats the air. Typical, furnaces pull air in from the outside. The heat exchanger heats the air quickly, and the air is blown into your home.
What is the limit switch on a furnace?
A furnace limit switch is a component of a forced-air furnace that is responsible for turning on the furnace blower once the desired heat has been met inside the furnace. Without a functioning furnace limit switch, a furnace would not be able to regulate the temperature in conjunction with a thermostat.
What controls a furnace?
The furnace thermostat is the nerve center of your home heating system. It’s the main control point that determines when and how much heat will be delivered by the furnace. But for all its mystery, the thermostat is actually a very simple device.

What are the different parts of a gas furnace?
Return Register Return registers look like normal air vents.
What parts of a furnace can be replaced?
Without question, the costliest part is the compressor, which is part motor and part vapor compressor. If, after 8 years the compressor fails, it may be time to think about buying an entirely new machine. If the compressor fails, it may jeopardize other parts of the system as debris from the motor and compressor sheathing infiltrate throughout.
