Technical Information
2.3
Temperature Control
The refrigerator with a SmartFresh compartment and freezer has 2 separate
cooling circuits.
The same evaporator cools both the cooling compartment and the
SmartFresh compartment in the refrigerator. If both areas require
simultaneous cooling, then the SmartFresh compartment has priority.
The cooled air passes through a flap mechanism, either directly into the
refrigerator or via an air duct (set in Styrofoam in the appliance rear wall) into
the SmartFresh compartment.
2.4
Interior Heater (R17/6)
A heater is set into Styrofoam in the rear panel of the appliance. The heater
switches on if the ambient-air NTC registers temperatures less than 82.4°F
(28°C).
2.5
Evaporator Fan (M2/4, M2/3)
The evaporator fan is turned on
for 30 seconds after the appliance door is closed
at the start of a defrost phase
when the compressor is turned on
The evaporator fan is shut off
when the appliance door has been opened for longer than 30
seconds
during a defrost phase, after it was activated at the beginning
2.6
Condenser Fan (M2/1)
The condenser fan is turned on when the compressor is turned on.

Table 030-11: Ambient Temperatures and Condenser Fan Speed
The condenser fan (Fig. 030-3, Item 2) draws in ambient air through the air
grille in the toekick area; the air then passes through the recess in the
compressor, and exits back through the air grille. The ambient air cools the
condenser (Fig. 030-3, Item 1) and the compressor (Fig. 030-3, Item 3). The
air grilles are installed 3.9 inches above the floor so that the appliance interior
does not get dirty.
