2°4. Ice Ejection Control Function
1. This is to eject ice from ice maker cube mould after ice making is completed.
2. if Hall IC signal is on within 3.6 seconds after ice ejection motor rotates in normal direction, it does not proceed ice
ejection but waits, If the ice bank is full ice ejection motor rotates in normal direction in every hour to check the condition
of ice bank. If the ice bank is not full, the water supply control starts after completion of ice ejection control. If the ice bank
is full, ice ejection motor rotates in reverse direction and sops under ice making or waiting conditions.
3. if ice bank isnot full, ice ejection starts. The cube mould tilts to the maximum and ice is separated from the mould and ice
checking lever raises.
4. Ice ejection motor stops for 1 second if Hall IC signal changes from OFF (low) to ON (high) after 3.6 seconds when ice
ejecSon motor rotates in normal direction. If there is no change in Hall IC signals within 1 minute after ice e}ection motor
operates, ice ejection motor stops as ice ejection motor or hall IC is out of order.
5. If ice ejection motor or Hall IC is abnormal, ice ejection motor rotates in normal direction to exercise initial operation. It
resets the ice maker if ice ejection motor or Halt IC is normal.
6. The mould stops for 1 second at maximum tilted conditions.
7. The mould returns to horizontal conditions as ice ejection motor rotates in reverse direction.

1. It is to force the operation during operation test, service, and cleaning. The test switch is mounted under the automatic
ice maker. The test function starts when the test switch is pressed for more than 0.5 second.
2. Test button does not work during ice ejection and water supply. It works when it is in the horizontal conditions. If mould is
full of ice during test function operation, ice ejection control and water supply control do not work.
3. When test switch is pressed for more than 0.5 second in the horizontal conditions, ice ejection starts irrespect of the
mould conditions. Water shall be splashed it test switch is pressed before the water in the mould freezes. Water shall be
supplied while the mould returns to the horizontal conditions after ice ejection. Therefore the problems of ice ejection,
returning to the horizontal conditions, and water supply can be checked by test switch. When test function performs
normally, buzzer sounds and water supply shall carry out. Check it for repair if buzzer does not sound.
4. When water supply is completed, the cycle operates normally as follows: Ice making • Ice ejection • Returning to
horizontal conditions , Water supply
5. Remove ice from the ice maker cube mould and press test switch when ice maker cube mould isfull of ice as ice ejection
and water supply control de not work when cube mould is full of ice.
2-6. Other functions relating to freezer compartment door opening
1, When freezer door is open, ice dispenser steps in order to reduce noise and ice drop.
2. When freezer door is open during ice ejection and cube mould returning to horizontal condition, ice ejection and cube
mould level return proceed.
3. When freezer door is open, geared motor and cube ice solenoid immediately stop and duct door solenoid stops after 5
seconds.
4. Water dispenser stops in order to protect water drop when freezer door is open.

ICE MAKER
MOTOR
The above ice maker circuit is applied to the GR-D267 and consists of the ice maker unit pert installed at the freezing room
and the ice maker ddving part of the main PWB.
Water supply to the ice maker container is done by opening the valve for the established water supply time by operating the
container via a solenoid relay for the ice valve of the solenoid valve placed at the M/C room. If the water supply time is
elapsed, water supply is automatically stop. This circuit is a circuit for implementing function such as ice removal, ice-full
detection, horizontal balancing end sense of ice-making temperature for the ice*maker container. Since ice-making
temperature sense is same as Jnthe temperature sense circuit part of the main PWB, refer to it.
Test switch input detection of the ice-maker is same as in the door switch input detection circuit of the main PWB.
1. This function is used in operation test, service execution and cleaning etc and performed if pressing the test switch
installed at the automatic ice-maker itself for more than 0.5 second.
2. The test switch operates in the horizontal status and test function is not input in the water supply operation. Ice removal
control and water supply control is not performed if full-ice is arrived during the operation of test function.
3. If pressing the test switch for 0.5 second or more in the horizontal status, ice removal operation is immediately performed
irrespective of the generation conditions of ice at the ice*making tray. Therefore, care is required since water may
overflow if operating test function in the water state that ice-making is not done. A cycle of water supply is performed in
the horizontal balancing operation after ice removal operation. Therefore, you can check any problem of ice removal
operation, horizontal operation and water supply. In this case. if test function is normally performed, "Ding~" buzzer sound
rings and water supply control is performed. Thus, no ringing of"Ding~" buzzer sound means failure and repair check
must be performed.
4. If water supply is completed, operation in the normal cycle of "ice making -_ ice removal , returning to hodzontst status
* water supply".

1. Load driving circuit
In even if opening the door of freezing room or cold storage room during operation of fan motor at the freezing room, this
circuit does not stop and operates at the standard RPM. In addition, if doors of freezing room or cold storage room, the
fan motor normally operates at the RPM previously operated.
(A). (B), (C) and (D) of door switch for the freezing room or cold storage room are connected to the door open sensing
circuit in parallel toward both ends of switch to determine door open at MICOM.
_€Since a door switch of the home bar is connected to door switch (C), (D) of the cold storage room, it senses door opening
if even one of both is opened.
The fan motor is immediately stop if opening doors of the freezing room or cold storage room at the TEST mode and it
immediately operates if closing them.
