    After ice is formed, ice maker drops ice cubes intoice storage bucket. During ice production, ice makerarm raises and lowers. When ice storage bucket isfull, ice maker arm turns ice maker off. Discard first 3harvests of ice after initially connecting refrigerator tohousehold water supply and after extended periodsof non-use.

    Stop ice production by raising ice maker arm. Adefinite click is heard when proper position isreached. Ice maker arm will remain in off positionuntil pushed down.

    Ice N Water Dispenser(some models)

    CautionTo avoid personal injury or property damage, observefollowing instructions: Do not operate dispenser with Deepfreeze door

    open. Do not put fingers, hands, or any foreign object into

    dispenser opening. Do not use sharp objects to break ice.

    Water Dispenser OperationIt takes approximately 1 minute after initially pressingdispenser bar before water dispenses after initialconnection of water supply. Discard first 10 to 14containers of water after initially connecting refrigeratorto household water supply and after extended periods ofnon-use. Dispense water by pressing sturdy wide mouthed

    container against water dispenser bar. Stop water dispensing by releasing pressure on

    bar. A small amount of water may continue to fall.Spill shelf is not self-draining. Large spills shouldbe wiped dry.

    Ice Dispenser Operation

    CautionTo avoid property damage, do not dispense icedirectly into thin glass, fine china, or delicate crystal.

    Select cubed or crushed mode by sliding lever ondispenser panel. Dispense ice by pressing widemouthed container against ice dispenser bar.

    ImportantReduce spraying of crushed ice by holding widemouthed container directly under ice chute and ashigh as possible in dispenser area.

    Stop ice dispensing by releasing pressure on barbefore container is full. Some ice will continue tofall. Do not remove container until last of ice falls.

    If dispensing ice continuously, dispenser motor isdesigned to shut off after 3 to 5 minutes. Motor resetsafter 3 minutes and dispensing can continue.A slight delay occurs when switching between cubed andcrushed modes. Pieces of crushed ice will vary in sizeand shape. "Snow" may form on door and ice chutewhen repeatedly dispensing crushed ice. Allow "snow" toevaporate or wipe dry.Dispenser operates only with cubes of proper size andcrescent shape. Do not add purchased ice cubes orother shaped cubes to ice bucket.

    Removing Ice Bucket Remove ice bucket by lifting bucket and pulling

    out. Replace ice bucket by sliding in until bucket locks

    in place. Ice bucket must be locked in place forproper ice dispensing. If Deepfreeze door doesnot close, bucket is not in proper location.

    Dispenser Light (some models)A light is activated when dispensing ice or water. Somemodels feature a night light. Activate night light by pushing switch, located

    underneath dispenser and left of ice dispenserbar.

    An open thermistor or thermistor circuit will result infailure of refrigerator to cool.Shorted thermistor will cause refrigerator to run 100percent of time except for defrost. Freezer temperature setting and thermistor value

    will determine if compressor/condenser fan andevaporator fan switches are open or closed.Compressor/condenser fan switch must be openfor 6 minutes before switch can close again(compressor dwell time).

    Cut-out and cut-in temperature values must bereached and maintained for 15 seconds beforeoutput state will change (digital delay).

    Adaptive Defrost OperationDefrost occurs after predetermined length ofcompressor run hours. Compressor run time betweendefrosts changes, or adapts, depending upon recenthistory of defrost lengths (time it takes for defrostterminator to open after defrost heater has beenturned on). Defrost terminator opens at 48F and closes at

    15F. Compressor run time between defrosts (CRTD)

    will be one of 3 values under normal operation:CRTD 1 (8 hours) or CRTD 2 (12 hours) or CRTD3 (16 hours).If defrost length is low (DT-LO defined as 21minutes) indicating small frost load, CRTD fornext defrost cycle is advanced to next level.If defrost length is high (DI - HI defined as 24minutes) indicating large frost load, CRTD fornext defrost cycle is lowered to next level.If defrost length is between 21 and 24 minutes,CRTD for next defrost cycle remains the same.Initial value at power up CRTD 0 is 4 hours.

    Vacation Mode CRTD equals 96 hours. VacationMode CRTD is interrupted with door openings.Defrost interval will revert back to interval beforeVacation Mode. Three things must occur to reachVacation Mode CRTD:1) Defrost interval must be CRTD 3 (16 hours).2) Both refrigerator and freezer doors must have

    remained closed since last defrost cycle.3) Defrost thermostat must have opened in less

    than 21 minutes during last defrost cycle. Six minute dwell time occurs after defrost

    terminator opens before compressor andcondenser fan motor will operate. Ten minutedwell time occurs after defrost terminator opensbefore evaporator fan motor will operate. Dwelltime can be bypassed by disconnecting power tothe unit for 30 seconds.

    Conventional defrost can be selected in ProgramMode B.

    Component TestingComponent Description Test ProceduresCompressor When compressor electrical circuit is

    energized, the start winding currentcauses relay to heat. After an amount ofstarting time, the start winding circuitturns off. The relay will switch off thestart winding circuit even thoughcompressor has not started (for example,when attempting to restart aftermomentary power interruption).With open relay, compressor will notstart because there is little or no currentto start windings. Overload protection willopen due to high locked rotor run windingcurrent.

    With shorted relay or capacitor,compressor will start and overloadprotector will quickly open due to highcurrent of combined run and startwindings.

    With open or weak capacitor,compressor will start and run as normalbut will consume more energy.

    Resistance test1. Disconnect power to unit.2. Discharge capacitor by shorting across terminals with a resistor for 1

    minute.3. Remove leads from compressor terminals.4. Set ohmmeter to lowest scale.5. Check for resistance between Terminals S and C Terminals R and C

    If either compressor winding reads open (infinite or very high resistance) ordead short (0 ohms), replace compressor.

    Ground test1. Disconnect power to refrigerator.2. Discharge capacitor by shorting terminals through a resister.3. Remove compressor leads and use an ohmmeter set on highest scale.4. Touch one lead to compressor body (clean point of contact) and the other

    probe to each compressor terminal.If a reading is obtained, compressor is grounded and must be replaced.

    Operation testIf voltage, capacitor, overload, and motor winding tests do not show cause forfailure, perform the following test:1. Disconnect power to refrigerator using power switch.2. Discharge capacitor by shorting capacitor terminals through a resistor.3. Remove leads from compressor terminals.4. Wire a test cord to power switch.5. Place time delayed fuse with UL rating equal to amp rating of motor in test

    cord socket. (See Technical Data Sheet)6. Remove overload and relay.7. Connect start, common and run leads of test cord on appropriate terminals

    of compressor.8. Attach capacitor leads of test cord together. If capacitor is used, attach

    capacitor lead to a known good capacitor of same capacity.

    9. Plug test cord into volt-watt meter to determine start and run wattage as wellas check for low voltage which can also be a source of trouble.

    10. With power to volt-meter, press start cord switch and release. If compressor motor starts and draws normal wattage, compressor is

    okay and trouble is in capacitor. relay/overload, freezer temperaturecontrol, or elsewhere in system.

    If compressor does not start when direct wired, recover system at high

    side. After system is recovered, repeat compressor direct wire test. Ifcompressor runs after recovery but would not run when direct wiredbefore recover, a restriction in sealed system is indicated.

    If compressor does not run when wired direct after recover, replace

    faul
