This draft inducer assembly is a critical component for maintaining safe combustion ratios and preventing pressure switch tripping in residential heating systems

This part is typically supplied as the elbow assembly itself

including the electromagnetic coil and the compatible valve housing for a full restoration of function

and heat pump sequencing where reliable inductive load switching is critical

ensuring the system remains depressurized until the thermal event is addressed and the part is replaced
