SAFE SERVICING PRACTICES - ALL APPLIANCES

To avoid personal injury and/or property damage, it is important that Safe ServicingPractices be observed. The following are some limited examples of safe practices:

1. DO NOT attempt a product repair if you have any doubts as to your ability tocomplete it in a safe and satisfactory manner.

2. Before servicing or moving an appliance:

• Remove the power cord from the electrical outlet, trip the circuit breaker to theOFF position, or remove the fuse.

• Turn off the gas supply.• Turn off the water supply.

3. Never interfere with the proper operation of any safety device.

4. USE ONLY REPLACEMENT PARTS CATALOGED FOR THIS APPLIANCE.SUBSTITUTIONS MAY DEFEAT COMPLIANCE WITH SAFETYSTANDARDS SET FOR HOME APPLIANCES.

5. GROUNDING: The standard color coding for safety ground wires is GREEN, orGREEN with YELLOW STRIPES. Ground leads are not to be used as currentcarrying conductors. It is EXTREMELY important that the service technicianreestablish all safety grounds prior to completion of service. Failure to do so willcreate a hazard.

6. Prior to returning the product to service, ensure that:

• All electrical connections are correct and secure• All electrical leads are properly dressed and secured away from sharp edges,

high-temperature components, and moving parts• All non-insulated electrical terminals, connectors, heaters, etc. are adequately

spaced away from all metal parts and panels• All safety grounds (both internal and external) are correctly and securely

connected• All panels are properly and securely reassembled

Running Your Refrigerator

Problem Cause CorrectionCompressor does not run.

Cooling system is turned Off. •

Refrigerator is in defrost •cycle.

Plug at wall outlet is •disconnected.House fuse blown or tripped •circuit breaker.

Power outage.•

Turn cooling system On. See Controls •Section for location of cooling system On/Off button.This is normal for a fully automatic defrost •refrigerator. The defrost cycle occurs periodically, lasting about 30 minutes.Ensure plug is tightly pushed into outlet.•

Check/replace fuse with a 15 amp time-•delay fuse. Reset circuit breaker.Check house lights. Call local Electric •Company.

Refrigerator runs too much or too long.

Room or outside weather is •hot.Refrigerator has recently been •disconnected for a period of time.Automatic ice maker is •operating.Doors are opened too •frequently or too long.Refrigerator/freezer door may •be slightly open.

Freezer control is set too cold •(control found in fresh food section).Fresh food/freezer gasket is •dirty, worn, cracked, or poorly fitted.

It’s normal for the refrigerator to work •longer under these conditions.It takes 8-12 hours for the refrigerator to •cool down completely.

Ice maker operation causes refrigerator to •run slightly more.Warm air entering the refrigerator causes it •to run more. Open doors less often.Ensure refrigerator is level. Keep food •and containers from blocking door. See Problem section, Opening/ Closing of Doors/ Drawers.Set freezer control to warmer setting until •refrigerator temperature is satisfactory. Allow 24 hours for temperature to stabilize.Clean or change gasket. Leaks in door •seal will cause refrigerator to run longer in order to maintain desired temperatures.

Compressor does not run.

Electronic control system •keeps the refrigerator at a constant temperature.

This is normal. Refrigerator goes on and off •to keep temperature constant.

Digital temperature displays are flashing.

Water collects on bottom side of drawer cover.

Vegetables contain •and give off moisture.

Moisture on the bottom side of the cover is not •unusual. Move humidity control (some models) to lower •setting.

Moisture collects in bottom of drawer.

Washed vegetables •and fruit drain while in the drawer.Fruits and vegetables •are kept past their prime

Dry items before putting them in the drawer. •Water collecting in bottom of drawer is normal.

Routinely clean out old fruits and vegetables •especially if they begin to break down.

Moisture collects on outside of refrigerator or between doors.

Weather is humid.•

Door is slightly •open, causing cold air from inside refrigerator to meet warm air from outside.

This is normal in humid weather. When •humidity is lower, the moisture should disappear.See Problem section, Opening/Closing of Doors/•Drawers.


Automatic Ice Maker

Problem Cause CorrectionIce maker is not making any ice.

Ice maker power switch is Off.•Water supply is not connected •to refrigerator.Household water line valve is •not open.Freezer is not cold enough.•

Valve on cold water pipe •is clogged or restricted by foreign material. If valve is of the self-piercing type, it may not have created a sufficiently sized hole in tube for water to pass through.Check to see if the water •dispenser is dispensing water.

Water filter is not completely •seated.

Turn on power switch.•Connect water supply (see • Installation Instructions).Turn on household water line valve. •

See Problem section, Temperatures Are •Too Warm.Turn off household water line valve. •Remove valve. Ensure that valve is not a self-piercing valve. Clean valve. Replace valve if necessary.

Ice maker is not making enough ice.

Ice maker is producing less •ice than you expect.

Freezer is not cold enough.•

Household water line valve is •not completely open.Check to see if water •dispenser is dispensing slower than normal.

Ice maker should produce approximately •4-5 pounds of ice every 24 hours. Fast Ice should produce up to 6 pounds of ice every 24 hours.See Problem section, Temperatures Are •Too Warm.Turn on household water line valve. •

If it is, replace the ice & water filter •cartridge.

Ice maker will not stop making ice.

Ice maker wire signal arm •is being held down by some item in the freezer.

Move item and release wire signal arm. •Remove any ice cubes frozen together over wire signal arm.

Ice maker is not separating the ice cubes.

Ice cubes are not being used •frequently enough.Ice cubes are hollow or •smaller than normal.

Remove and shake ice bin to separate •cubes.The ice & water filter cartridge may be •clogged. Replace filter cartridge.

Ice has bad odor and taste.

Ice has picked up odor or •flavor from strong food stored in refrigerator or freezer.Ice not used frequently enough.•

Cover foods tightly. Discard stale ice. Ice •maker will produce fresh supply.

Discard stale ice.•

Ice Dispenser

Problem Cause CorrectionDispenser will not dispense ice.

Water supply is not connected.•

Ice storage container is empty.•

Freezer temperature is set too •warm.

Household water line valve is •not open.

Freezer door is not closed.•

Ice dispensing arm has been •held in for more than 4-5 minutes.

Connect water supply (see Connecting The •Water Supply section).Ensure ice maker is turned on. When the first •supply of ice is dropped into the container, the dispenser should operate.Turn freezer control to a higher setting so that •ice cubes will be made. When first supply of ice is made, dispenser should operate.Open household water line valve. Allow •sufficient time for the ice to be made. When ice is made, the dispenser should operate.Ensure freezer door is closed. (See Problem •Section, Opening/Closing of Doors/Drawers)Motor is overloaded. Motor overload protector •will reset in approximately 3 minutes. Ice can then be dispensed.

Ice dispenser is jammed.

Ice has melted and frozen •around auger due to infrequent use, temperature fluctuations, and/or power outages.Ice cubes are jammed between •ice maker and back of ice container.Ice cubes are frozen together. •

Ice cubes are hollow or smaller •than normal.

Remove ice container, thaw, and empty the •contents. Clean container, wipe dry, and replace in proper position. When new ice is made, dispenser should operate.Remove ice cubes that are jamming the •dispenser.

Use the dispenser often so that cubes do not •freeze together.The ice & water filter cartridge could be •clogged. Replace the filter cartridge. Dispensing system operates best at 30-100 psi water pressure. Well water pressures should fall within this range.

ed period of time, an alarm will sound and the door ajar indicator will display in the middle of the display. The alarm is turned off by closing the door. The mute sounds key will illuminate to prompt the reset of any pending alarms. Press this key to reset any system Alarms.

High Temperature In the event of a high temperature condi-tion, the temperature display will display “HI,”. After 20 minutes and the high temp alert will be displayed and the alarm off icon will illuminate until pressed, acknowl-edging the alarm, at which time the highest temperature reached will be displayed and the refrigerator will resume normal opera-tion. All other modes are turned off until the alarm is acknowledged.

Power Failure Alert In the event of a power failure, the power fail alert will be displayed and the temperature display will illuminate until the alarm off icon is pressed, acknowledging the alarm. Other modes may be turned off until the alarm is acknowledged. The power fail alert is turned off and the refrigerator will resume normal operation. The high temp alarm may also be illuminated until a safe operating range temperature has been reached.

Sabbath Mode is turned ON and OFF by pressing and holding both the outermost “-” and “+” indicators for five seconds for both the Wave-TouchTM and IQ-TouchTM modes. The display shows “Sb” while in Sabbath mode.

In the Sabbath Mode, the High Temp alarm is active for health reasons. If a high temperature alarm is activated during this time, for example due to a door left ajar, the alarm will sound intermittently for about 10 minutes. The alarm will then silence on its own and a red high temperature icon will display. The high temp icon will continue to display, even if the door is closed, until the Sabbath mode is exited and the icon reset. The refrigerator will function normally once the door is closed, without any violation of the Sabbath/Holidays.

10. Reassembleunit.

CAUTIONCheck the serial plate for the correct refrigerant type. It is extremely important to verify the type of refrigerant in the system before starting any sealed system repairs.

With the possible exception of the vacuum pump, all service equipment that comes in contact with R-134a during evacuation and recharging must be dedicated. Accordingly, R-134a will require a dedicated charging cylinder, manifold gauge set, process tube adaptors, and hoses. Any residual mineral oil on other tools (tubing cutter, etc.) must be thoroughly cleaned off before using on R-134a/Ester oil systems. It will be necessary to check with the manufacturer of your vacuum pump for refrigerant and oil compatibility issues.

If you use a vacuum pump with mineral oil to evacuate an R-134a system, it is ABSOLUTELY ESSENTIAL to have a shut-off valve between the pump and your manifold gauge set as shown on page Figure E2. The hand valve must be closed during all times when the vacuum pump is not operating. This will prevent the migration of mineral oil vapor into the R134a/Ester oil system. If the vacuum pump should stop during evacuation for any reason, the hand pump shut-off valve must be closed immediately.

Insure that your refrigeration hoses are specified for use with R-134a refrigerant. Research has shown that compounds in standard refrigeration hoses may enter sealed systems and ultimately restrict the cap tube in an R-134a system.

Evacuating System

WARNINGR-134a systems are particularly susceptible to moisture contamination which can only be prevented by evacuating the system for a minimum of 30 minutes to attain a minimum 29.9 inch (500 micron or lower) vacuum.

Charging The System

CAUTIONCheck the serial plate for the correct refrigerant type. It is extremely important to verify the type of refrigerant in the system before starting any sealed system repairs.

After charging the system with liquid be certain to wait at least 5 minutes before starting the compressor to give the refrigerant a chance to disperse throughout the system. Otherwise the compressor could be damaged by attempting to pump excessive quantities of liquid.

Preparing The Charging Cylinder:

CAUTIONIf you use a vacuum pump with mineral oil to evacuate an R-134a system, it is ABSOLUTELY ESSENTIAL to have a shut-off valve between pump and your manifold gauge set as shown in Figure E2. The hand valve must be closed during all times when vacuum pump is not operating. This will prevent migration of mineral oil vapor into R134a/Ester oil system. If vacuum pump should stop during evacuation for any reason, the hand pump shut-off valve must be closed immediately.

When the glass is pulled away from the actua-tor the Actuator switch will open the signal to the lower control board. The lower control board will send a 12 VDC signal to the relay board for 10 mill-a-seconds to unlock the door linkage allowing the ice door spring to close the ice door. (See Figure 11) This will close the contacts on the ice door switch telling the lower control board the door is closed. If the switch contacts do not close the lower control board will send a 12 VDC signal to the relay board for 10 mill-a-seconds again to un-lock the door linkage allowing the ice door spring to close the ice door. The lower control board will continue to do this until the ice door is closed.

Low/No Voltage One point we need to cover in our testing is good connections at all points in the ice and waterAt Coil(s) wiring. There are a number of connections in the wiring of a refrigerator. On the ice maker, the

wiring runs through the plug by the condenser fan motor up to the ice maker, back down to thesame plug and into the diode harness. On the water dispenser the wiring runs from the plug bythe condenser fan motor to the plug at the bottom of the freezer door up to the dispenser andback down through the same plugs to the diode harness. A bad connection at any of the plugsor wire terminals can stop the valves from operating. One of the problems we have found is atthe connector on the water valve coils is pushed on with the valve terminal over top the terminalin the plug. (See Figure H9.)

VOLTAGE READINGS AT GREEN COIL OF SECONDARY VALVE

When Ice Maker is Filling:

Voltage at Outlet Voltage at Coil

120 VAC 100 ± 10% VAC Normal

100 VAC 85 ± 10% VAC Normal at 105 VAC (Will require use of 50 watt coil)

100 - 120 VAC 20 - 76 VAC Bad connection, Fill Switch, or Heater in Ice Maker.

VOLTAGE READING AT YELLOW COIL OF SECONDARY VALVE

When Filling A Glass With Water:

Voltage at Outlet Voltage at Coil



100 - 120 VAC 0 - 90 VAC Bad connection or bad Fill Switch

VOLTAGE READING AT COIL OF PRIMARY VALVE

When Ice Maker is filling:

Voltage at 0utlet Voltage at Coil

120 VAC 56 ±10% VAC Normal


100 - 120 VAC 10 - 43 VAC Bad connection, Fill Switch, or Heater in Ice Maker

100 - 120 VAC 0 VAC Open Diode (if current is normal at secondary coil)

NOTE: You must remember that with the current flowing to the Primary Valve Coil through the Diode, you are getting 30 cycle instead of 60 cycle current at the coil of the Primary Valve. Because of this, your volt meter will only read about 1/2 the voltage that is going to the coil. The change in the cycle of current does not effect the efficiency of an electromagnetic coil.
