Different Parts of the Nordyne furnace and Their Functions

The Nordyne furnace is made of several essential parts, each of which plays a vital role in the proper functioning of the unit. The following is a brief overview of the crucial components of the NORDYNE furnace:

  • Limit Switch – A limit switch is a safety device to prevent the furnace from overheating. If the temperature inside the furnace gets too high, the limit switch will shut off the gas supply to the burner.
  • Furnace Ignitor – The ignitor’s function is to ignite the gas inside the furnace. It is usually made of ceramic or quartz and glows white-hot when turned on.
  • Furnace Door Latch – The door latch helps keep the door of the furnace closed, preventing air from leaking out and keeping the heat inside the furnace.

  • Furnace Pressure Switch – The function of the pressure switch is to monitor the pressure inside the furnace. If the pressure gets too high, the switch will shut off the gas supply to the burner.
  • The Blower – The blower is responsible for circulating the heated air throughout the home. Nordyne furnace uses the squirrel cage blower and the multi-speed blower. The squirrel cage blower is the most common type used in NORDYNE furnaces and can move a large volume of air at a single speed. On the other hand, the multi-speed blower can carry a smaller volume of air at multiple speeds.
  • Flame Sensor – The flame sensor detects whether or not a flame is present inside the furnace. If the sensor does not detect a flame, it will shut off the gas supply to the burner.
  • Draft Inducer Motor – The draft inducer motor creates negative pressure inside the furnace. It helps to pull air through the furnace and prevents the back-drafting of combustion gases.
  • Control Board – The control board controls all of the functions of the furnace. It turns on the ignitor, regulates the gas flow, and controls the blower motor.

  • The Heat Exchanger – The heat exchanger is responsible for transferring the heat from the burning fuel to the air circulated by the blower. Nordyne furnaces use two types of heat exchangers: the shell and tube and the plate. The shell and tube types are more efficient than the plate type. But they are also more expensive.
  • The Flue Pipe – The flue pipe is responsible for carrying the exhaust gases from the furnace to the outside of the home. This component is made of stainless steel, which can withstand high temperatures.
  • The Thermostat – The thermostat is responsible for regulating the temperature inside the furnace. The thermostat is typically mounted on a wall near the furnace and is controlled by a switch on the furnace.
