Cold air is blown into the refrigerator compartment by the
Freezer Fan Motor that "pushes" the air through the
Evaporator Cover (1) reaching the internal Duct (2) and at
the same time is "pulled" by the refrigerator Fan Motor
(exhauster), following to the refrigerator Diffuser/ducts (3)
and going out through the outlets/ windows at the different
levels of the Wind Flow (Internal Refrigerator Diffuser).
After circulating through whole Refrigerator compartment,
the "hot" air come back through the return duct (4) located
on the lower right corner of refrigerator compartment,
where the Anti-Bacteria Filter is located (not available in
some models), returning again to the Evaporator that will
cool down the air and make this a cyclic operation.
Inlet and Outlets air Ducts have different paths, therefore
both are inside/ internal of the cabinet.
The refrigerator air Diffuser has a Wind Flow System
(inside duct), which provide a better air distribution over
this compartment due to the many outlets/ windows
available.
2- Remove the plastic Cover, then disconnect the
fan motor Connector
