12-9) When Ice Water Valve does not operate (Option)

Pre-Check
1. While disassembling,make sure to cut off water since the ice water valve is directly
connected with water.
2. Make sure to avoid the electric shock while disassembling because one end of wire is
applied with power.
3. Check the operation of the ice water valve only after the ice maker test switch is pressed.
