Trane EXC1278 Heat Exchanger W/Receptacle

The Trane EXC1278 is a heat exchanger with a receptacle, a crucial part of a gas furnace. Technically, it refers to a knob of metal compartments connected with several thin corridors through which the heat exchange takes place. The now-warmed air is channeled throughout the living space to warm and comfort you. The probe on the Trane may well be used for opening a line for a temperature sensor or safety control. In case of overheating, the control can turn off the furnace to avoid damage
