Air Flow
Cold air is circulated into the compartment by
the evaporator fan. When cooling is required,
the main board opens the damper and turns on
the fan to push cold air from the evaporator up
and out the air tower. The air circulates through
the refrigerator compartment and is pulled back
to the freezer below the evaporator by the way
of the air return passage behind the evaporator.
That warm moist air then gets pull back across
the evaporator coil to extract the heat and
moisture.
Cold air is circulated in the freezer by the
evaporator fan. When cooling is required, the
main board turns on the fan to circulate cold air
from the evaporator through the evaporator cover.
The air is pulled back to the evaporator through
two ducts built into the bottom of the evaporator
cover. That air then gets pulled back across the
evaporator coil to extract the heat and moisture.
Freezer air is circulated into the ice box by the
ice blower fan located in the freezer. The blower
pushes freezer air up and through the top ice
box air duct. Air in the ice box is then forced
out through the return air passage (bottom air
duct) to mix and be circulated with the rest of the
freezer air.
