Dispensing Functions
The water function is controlled by the main control
board. To select this function, press the cradle on
the dispenser.
Dispenser Lock
When the dispenser system is locked, no dispenser
command will be accepted. This includes the
dispenser cradle and will prevent accidental
dispensing that may be caused by children or pets.
If the touch screen, pad, or the cradle is depressed
with the system locked, it will be acknowledged with
three pulses of the LOCK LED accompanied by an
audible tone.
To lock or unlock communication between the
dispenser and main control board, press the LOCK
pad and hold it for 3 seconds. The LOCK LED will
fl
ash while the LOCK pad is pressed. When the
communication is locked, the LOCK LED will be
illuminated.
On some models, the status of other functions
selected prior to the initiation of the lock feature will
be displayed. If the lock is engaged while a mode is
active, the LED will remain on until that mode times
out.
If the lock is engaged when the
fi
lter timer expires,
the LED will come on but cannot be reset until the
lock is turned off.
The lock feature will be restored in the event of a
power disruption.

Liner Protection Mode
The refrigerator incorporates a liner protection
mode for the freezer section. The freezer evaporator
fan will start and run on high speed if any door
or drawer has been open for 3 minutes. Air will
circulate into the fresh food section if the damper is
in the open position.
This mode is controlled by 2 timers. Timer #1
monitors door/drawer-open time. A 3-minute door/
drawer-open count begins when a door/drawer is
opened. If 3 minutes elapse before the door/drawer
is closed, the liner protection mode will become
active. Once the door/drawer is closed, timer #1
resets and liner protection mode goes into standby.
In standby, normal fan operation resumes and timer
#2 begins a 3-minute door/drawer-closed count. If
3 minutes elapse without a door/drawer opening,
liner protection mode will completely deactivate. If
a door/drawer is opened within the timer #2 door/
drawer-closed count, the remaining time in the
door/drawer-closed count will be deducted from the
timer #1 door/drawer-open count.
Defrost Cycle
The refrigerator utilizes an adaptive defrost cycle
that operates a glass enclosed heater to remove
frost from the evaporator. The defrost cycle has
changed from 60 hours adaptive defrost to 96 hours
adaptive defrost.
The control board determines the length of time the
heater is energized. It does this by monitoring the
freezer evaporator thermistor. Once the temperature
of the thermistor reaches 50°F, the control cycles
the defrost heater off. A bi-metal safety thermostat
provides a backup in the event the evaporator
thermistor fails. The safety thermostat prevents the
temperature from exceeding 140°F.
Note:
Refer to Pub# 31-9062 for information about
basic adaptive defrost.
Automatic Quick Ice Feature
When the main board senses icemaker water valve
operation, a timer in the main board will run the
evaporator fan (when the sealed system is off) for
120 minutes and then return to normal operation.
At every water valve cycle the timer is reset to zero
and counts to 120 minutes. Increased evaporator
fan operation provides approximately even ice
production in 90° (longer compressor on-time) to 70°
(longer compressor off-time) ambients.
