4.2 Internal Air Flow
4.2.1 Ice & Water Models
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.
