Amana-Goodman B1370126 Air Pressure Switch -0.40"WC

The Amana-Goodman B1370126 Air Pressure Switch is an essential safety component designed for use in various Heating, Ventilation, and Air Conditioning systems, particularly within Goodman and Amana furnaces. This part has an essential function in the control of the furnace operations in particular, the control of the pressure within the venting system. This switch is designed to sense the absence of pressure or negative pressure in the furnace venting. This negative pressure is developed by the inducer motor which is used to expel the combustion gases from the furnace to the outside of the building.
