MOTOR
The above ice maker circuit is applied to the R S65DQG/DSG,
R-S65DRG
and consists of the ice maker unit part installed
at the freezing room and the ice maker driving 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 and sense of ice-making temperature
for the ice-maker container. Since ico-making
temperature
sense is same as in the 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 hodzontal 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 ff operating test function
in the water state that ica-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 horizontal status
•., water supply",
