Additional Regulating of Refrigerator Compartment Temperatures (Except Over/Under Models):
Details of Controlling the Refrigerator Drawers Temperature
The refrigerator zone (except in 30", 36" and 42" over/under models), contains a diverter behind the evaporator
cover, below the evaporator and just above the refrigerator drawers. At the bottom of the evaporator cover is a
series of holes and an air diverter near the location of the diverter. The refrigerator air is drawn from the compart-
ment and pushed down through the evaporator, some air is diverted through the holes in the evaporator cover to the
upper refrigerator compartment and some is allowed past the diverter. Since cold air sinks, this cooling method
allows for the drawers to
remain approximately 2°F (1°C)
colder than the rest of the com-
partment. However, if the com-
partment thermistor detects
temperatures below 35°F (2°C),
the defrost time is extended
slightly to avoid freezing tem-
peratures in the drawer area.
NOTES:
• During Sabbath Mode the
lighting system is disabled
so the evaporator fan may be
observed running when the
door is open.
• In over/under models, the
refrigerator air flow is up
through the evaporator, so
there should be no tempera-
ture difference in the drawer
area.
1. Fan cycles on and off dur-
ing normal operation, but if
temperatures fall below 35°F
(2°C), fan switches off
