Is DC Power (5V and 12V)
output normal?
Failed DC Power
• Check DC power (5V, 12V).
Change main PWB
Is cube ice led off during
troubleshooting check?
Failed ice making sensor
• Check the resistance of
both ends (1,2) of ice making
sensor of CON8.
• Defects between ice making
sensor and board
(Pin No. 60 of IC1)
Replace Ice making
Sensor
Is Crushed Ice LED off during
troubleshooting check?
Failed Ice Maker Unit
• Is the resistance of both ends
9,10 of ice ejection motor of
CON8 between 18 and 22
Ω
?
• Is ice ejection motor drive circuit
(IC11 and peripheral circuits)
normal?
• Defects between Hall IC and
Board (Pin No. 42 of IC1).
• Confirm ice ejection and level
return when pressing
test switch.
Replace Ice Maker Unit
Replace Main PWB
Are ice
ejection and level return
normal when test switch is
pressed for more than 0.5 second?
Does the bell
sound once?
Failed ice maker unit test switch
• Are both ends 5,6 of CON8
test switch open?
• Defects between test switch
and board (Pin No. 43 of IC1).
• Are both ends (3,4) of CON8
ice maker stop switch short?
Replace Ice maker Unit
Replace water
supply valve
• Is power applied to water
supply valve?
• Does the water supply
valve work normally?
• Is the water supply line
normally connected?
Poor water supply
Is water suppy normal
after Ice ejection and level return
by ice ejection motor?
Normal
