Under the freezer hinge cover arethe electrical connections for thefront display panel. All electronicsand control circuits are in the rearcontrol compartment. The displaypanel is just data input and display.

Connections through the upperfreezer door hinge.There is also thermistor to monitorthe exterior temperature under thishinge cover. The thermistor is on avery short harness.

The units use a hot wall condenserin conjunction with a sub-condenser. The hot wall condenserloop is manufactured from steel.The Hot Pipe Post Condenser Loop(Yoder Loop) is constructed fromcopper tubing. There are twoevaporators. The capillary tubefeeds into the fresh food evaporatorand the outlet from the fresh foodevaporator supplies the freezerevaporator.

The temperature settings willdisplay the current set-point the firsttime that the "Fridge Temp" or"Freeze Temp" buttons are pressed.Each subsequent pressing of thecontrols will decrease the set-pointuntil the minimum is reached.Pressing the control again will cyclethe control to the maximum setting.

Press the child lock button for 3seconds, the child lock indicatorcomes on with an audible tone. Nofunction commands except the icetype button will be accepted. Thisfunction will prevent accidentalsettings. To unlock this function,press and hold the child lock buttonfor 3 seconds.

The ice type button selectsCubed/Crushed/Ice-off options insequence. The default setting isCubed Option. If ice off is selected,the ice maker will stop working, thisoption will be terminated whenCubed or Crushed options areselected.

Power Freeze:When the power freeze button isdepressed, the power freezeindicator light comes onimmediately. The compressor andfan run continuously for a set timeand temperature depending onmodel.Power Cool:When the power cool button isdepressed, the power cool indicatorlight comes on immediately. Thecompressor and fan runcontinuously until the refrigeratorreaches 25F.Refer to the service flash. Pre June2003 production Power Freezeoperation differs from post June2003 operation.

Filter indicator light: This indicatorlight is normally green, after 5months of service it changes toorange, at the 6th month it changesto red.To reset: depress the Ice Type andChild Lock buttons for 3 seconds.This is strictly a time-basedfunction, this does not monitorwater usage.

Self-Diagnostic Function

* S e lf- dia gn os tic s c he ck lis tE r r o r

When power is first applied, thesystem performs a power-up selfcheck. Any failure of an activecomponent will result in a specificsegment of the display illuminating.There are two versions of the self-diagnostic output. On unitsproduced before June 2003 will notdisplay for Refrigerator Defrosterrors (7) or Freezer Defrost Errors(13). The self diagnostics can beactivated by pressing the "PowerCool" and "Power Freeze" buttonsat the same time for eight seconds.

Offsets are included that will allowfor adjusting to the characteristics ofthe thermistors. Hold the FreezerTemp and Power Cool buttons fortwelve seconds. It is highlyrecommended that theseadjustments are avoided.

The Fridge Temp display showswhich mode the adjustment is beingmade to. There are four differentthermistors that can be adjusted.Freezer offset is mode "0". FreshFood offset is mode "1". Ice Makerthermistor offset is mode "4".CoolSelect zone is mode "20".Icemaker fill time can be adjustedwhen in mode "3". It is stronglysuggested that the icemaker fill timeshould not be adjusted.The Freezer Temp display indicatesthe amount of the offset based uponmemory tables. It is imperative thatthe reference tables be used whenmaking an offset adjustment. Thevalues displayed in the FreezerTemp display are not the actualoffset temperatures.In this example, the freezerthermistor is being offset by -6degrees.

Defrost Function

15

Since there are two evaporators inthe system, there are two evaporatordefrost heaters.Defrost is adaptive and willterminate based upon the evaporatorthermistor temperature readings.The system is designed to defrostthe fresh food section twice as oftenas the freezer section. Thiscompensates for the fact that thefresh food section is accessed morefrequently than the freezer section.The fresh food section can defrostindependent of the freezer section,but the freezer section will alwaysdefrost at the same time as the freshfood section. The fresh food sectionwill defrost once for every six toeight hours of compressor run timewhile the freezer section will defrostevery twelve to sixteen hours ofcompressor run time.When started from roomtemperature, the first defrost cyclewill begin after four hours ofcompressor run time.The defrost temperature ismonitored at the bottom right of thefreezer evaporator and at the top leftoutlet of the refrigerator evaporator.


20/74

Forced Operation Function

16

The forced operation check allows aforced check of the cooling system.Each mode will operate until thenext mode is selected or until thetest is cancelled. The forced modecannot be activated if the unit isdefrosting either of the evaporatorcoils.The compressor will run for 24hours and then begin cycling at -14degrees in the freezer and 34degrees in the fresh foodcompartment.Loss of power will also cancel thisfunction. There is no delay incompressor start so if there is highhead pressure, an overload conditioncan be encountered.The three individual tests are;Forced compressor pull-down,Refrigerator defrost check andrefrigerator and freezer defrostcheck.To enter the forced operation mode,depress the Power Freeze and theFridge Temp buttons for eightseconds.


21/74

Press any but ton except " ICE TYPE" or "CHILD

Pressing the "Ice Type" or "ChildLock" buttons will cancel this modeof operation.During each test the timing of thebeeps will vary.

Forced Operation Function

Condenser Fan Delay The condenser fan operation willchange depending on the ambienttemperature. Above 65 degreesFahrenheit, the condenser fan willbegin operation with thecompressor. Between 61 and 65degrees, the condenser fan energizesfive minutes after the compressorenergizes. Below 60 degrees, thecondenser fan will not operate. Thisfunction is used to promote good oildistribution within the compressor.

21

The board uses a high efficiency,high frequency power supply toconvert the line voltage to +12 and+5 volts DC.If this supply does not provide thecorrect DC voltages, the thermistorswill all sense temperatureincorrectly.

Each evaporator has it's own drainhose. Make sure that these hoses areinstalled with the slots near thebottom.

When installing drain tubes be surethe slot end is installed down andthe tube is secured into theembossment in the drain pan

The thermal fuse (safety) is locatedon the lower right side of theevaporator.If this fuse is open, the appliancewill operate for four hours orcompressor run time, attempt thefirst defrost and fail to return tonormal operation.

The freezer evaporator thermistor ismounted in the lower right sectionof the evaporator coil.

The evaporator heaters are notreplaceable separate from theevaporator itself.The bimetal mounted in the top ofthe freezer evaporator in productmanufactured before June 2003. Thebimetal effectively bypasses theevaporator thermistor attemperatures below 23 degrees. Thebimetal opens at 54 degrees and thethermistor will provide actualevaporator temperature data to thesystem control.Production after June 2003 shouldnot include the bi-metal.

Thermistors are all the same sensorwith different harnesses attacheddepending on the mounting. It ispossible to either check theresistance of the sensor with theconnection unplugged, or check theDC voltage of the sensor.On the bottom freezer refrigeratorthere is no offset adjustment of thethermistors.

The fresh food and freezerthermistors can be adjusted byclipping out diodes on the mainboard. It is suggested that thisapproach not be used. Either replacethe thermistor that is out of range orreplace the main control boarddepending on the fault condition.

There is a low voltage transformerthat supplies 9VAC and 13VAC.The test switch will initiate a defrostcycle. The first press will initiate aforced pull-down. The second timeit is pressed, the fresh food sectiondefrosts independent of the freezersection. Pressing a third time willinitiate a combined fresh food andfreezer defrost. Pressing the testbutton again will cancel the forceddefrost.
