Regulate Freezer Zone Temperature (700BCI-3, 700BFI-3)
When the thermistor in the freezer compartment reaches high off-set temperature, calling for cooling, the compres-
sor and condenser fan are energized, but the evaporator fan is not allowed to run until the thermistor on the evapo-
rator reaches 35°F (2°C). (See Figure 3-19)
If either drawer is opened while the evaporator fan is operating, the microprocessor will detect the power signal to
the lights and cut power to the fan.
Though compartment air temperatures will fluctuate, LCD displays average temperature.
NOTE:
If compartment temperature exceeds either high or low offset (Ex: drawer is left open), temperature display
will change by one
degree per minute.
NOTE:
If freezer
compartment thermis-
tor is faulty, compres-
sor operation defaults
to 20 minutes ON, 20
minutes OFF cycling,
EE appears in left of
LCD, SERVICE will
flash and Error Code
07 will be logged.
NOTE:
If evaporator
thermistor is faulty,
the compressor will
be energized after
the dwell time and
the evaporator fan
will be energized 3
minutes later. SER-
VICE will flash and
Error Code 08 will be
logged.
NOTE:
When in
Sabbath Mode, the
freezer compartment
thermistor still con-
trols compressor
operation, except
there is a random 15
to 25 second delay
before the compres-
sor is energized.
