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.
