Internal Air Flow

The freezer fan draws air through the evaporator and into a duct in the rear wall of the freezer
compartment. This air exits through the fan grill at the top of the freezer compartment. The air
behind the freezer coil cover is also diverted through the divider partition to another fan, which
supplies the cold air into the PC compartment. The amount of air is controlled electronically by two
sensors, which in turn regulate, through the power/control module, the speed of both PC and FC
fans to maintain selected temperatures in each compartment.
Air from the PC returns to the FC evaporator by way of the return air duct, which is built into the
divider partition. This air is drawn across the evaporator by the FC fan motor to be recirculated
again throughout the PC/FC compartments.
