Air Circulation
The evaporator fan circulates air inside of the refrigerator and freezer sections. ( Fig. 65) Most of the
air circulates inside the freezer compartment, and returns to the evaporator from two directions. The
first route is through a series of slots between the evaporator cover and the rear edge of the freezer
floor, where it passes under the evaporator cover, and up through the evaporator coil. The second
direction is through slots in the front of the freezer floor. The return air travels between the floor and
the liner, where it joins other return air at the back, flowing beneath the evaporator cover and up
through the evaporator coil.
Some of the air from the evaporator fan travels down the air tower into the refrigerator compartment,
and is discharged through the diffuser. The amount of air entering the refrigerator compartment
through the diffuser is determined by the position of the air damper. As the freezer control knob is
turned, it moves the damper over the opening of the diffuser, thus varying its size, and controlling the
amount of air into the refrigerator compartment.
The fan draws circulating air from the refrigerator through return air ducts at the back of the refrigera-
tor-freezer partition. From there, the air travels up behind the evaporator cover, and up through the
evaporator coils. The fan again forces the air into the freezer and refrigerator compartments, to
complete the cycle.
