Error code 72 Carrier furnace
In the following section, I will outline what Carrier furnaces are and what it means when you get the error code 72.
Carrier furnaces are designed to provide a reliable gas furnace for a long period. These furnaces mainly use natural gas and oil as fuel.
When you turn on your Carrier furnace, the first thing that will happen is that it will detect the position of its door and open it by turning a key in a lock handle. It will then turn on its main burner to begin warming air inside its combustion chamber, which burns the fuel to heat up the air until it reaches the proper temperature. These furnaces have an automatic ignition system which ensures that they start automatically without any manual intervention from anyone.
The ignition system consists of three sensors which monitor the furnace’s movement, flame height and temperature inside the combustion chamber and an automatic safety valve that senses any malfunction with the burner or ignition sensor and shuts down the furnace when necessary.
