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

The temperature display will begin to blink with the first touch. After five seconds of inactivity, the display will beep to accept the new temperature. After 10 seconds, the display times out and returns to the basic display.
AlarmsDoor Ajar If the door has been left open for an extend-
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.

80 Section E - R-134a Service Information
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.)

When Filling A Glass With Water:
Voltage at Outlet Voltage at Coil
120 VAC 119 ± 10% VAC Normal
100 VAC 99 ± 10% VAC Normal
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 VAC 48 ± 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.
