Introduction
*The new Profile bottom mount refrigerators have the following features:
• They are available in 25 and 21 cubic foot capacity with fresh food single or French door
configurations.
• An anti-tip kit will be required for the 21 cu. ft. models.
• They are icemaker ready or have a factory installed icemaker.
• The French door models feature optional filtered external water dispenser.
• Two coil water tanks provide added storage volume with increased surface area for quick
temperature recovery.
• They are ENERGY STAR® rate and have a variable speed inverter compressor and fans on
all models.
• They are equipped with up front, electronic touch temperature controls with digital
temperature display.
• An external "air" thermistor changes the control setting based on ambient condition to
keep the fresh food and freezer compartments at the correct temperature.
• A damper/air inlet assembly in the fresh food section creates more usable space on the top
shelf.

Introduction (cont.)
• An articulating door mullion attached to the right side door (French door
models), provides a movable center mullion that maximizes access to the fresh
food compartment.
• They are equipped with two self closing freezer drawer cam and lever
mechanisms that automatically pull the drawer shut when it is within 1 inch of
the closed position.
• They feature a BrightSpace™ interior with GE Reveal™ lighting.
• They are available in white, black, bisque, or stainless finish.
• Trim kits are available that allow adding decorator or wood panels to match
kitchen cabinets.
• There is a new nomenclature, (PDSF5NBWABB instead of PDSF25NBWABB). The
cubic foot volume was previously specified as 25, now it only shows as 5.
* Features may vary by model.

Defrost Cycle
The refrigerator utilizes an adaptive defrost cycle that operates a glass
enclosed heater to remove frost from the evaporator. Defrost time 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 70°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.

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 the door 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-open time. A 3-
minute door-open count begins when the door is opened. If 3 minutes elapse
before the door is closed, the liner protection mode will become active. Once
the door 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-closed count. If 3 minutes elapse without a door opening, the
liner protection mode will completely deactivate. If a door is opened within
the timer #2 door-closed count, the remaining time in the door-closed count
will be deducted from the timer #1 door-open count.

Airflow
• The evaporator fan forces air through the evaporator into
the freezer compartment. Air from the evaporator is also
forced through the electronic damper to the air tunnel outlet,
through the fresh food compartment, and returns to the
evaporator. The fresh food compartment receives chilled air
through an electronic damper at the bottom, rear of the
fresh food compartment. The damper is controlled by the main
control board. When open, the damper allows chilled air from
the freezer to move into the fresh food compartment.
• Air returns from the fresh food compartment to the freezer
compartment via two vents located to the left and right of the
electronic damper.

Evaporator Fan
Fan speed is selected and maintained by the main control board regulating the
length and frequency of the 13.6 VDC pulse. Temperature can cause some fan
speed variation. Fan speed can vary +/- 5%, depending on the temperature, with
higher temperatures causing slightly higher speeds.
The evaporator fan has a 4-wire connection:
White Wire (DC Common)
The white wire is the DC common wire used for testing. During repairs, DC polarity
must be observed. Reversing the DC polarity causes a shorted motor and/or board.
Red Wire (Supply)
Each motor uses an internal electronic controller to operate the motor. Supply
voltage from the main control board remains at a constant 13.6 VDC.
Blue Wire (Feedback/RPM)
On previous Arctica models, the blue wire reported rpm (speed) information to the
main control board for speed control purposes. On this model, the board does
not require or read any feedback information from the fan motor.
