2. Operation Principles
1) While Opening
When power is on and the inlet water pressure reaches
at a certain value, the plunger (3) moves up by solenoid
coil. The water passes through porous hole and then
center holes of the holder and flows to the outlet. Flow
control (6) and flow washer (7) are included in order to
maintain a constant flow rate and pressure (1.0 ~
8.0 kgf/cm
2
) in A line (water supplied to icemaker).
2) While Closing
The water stops flowing to outlet as packing seals (4)
the hole of holder (5) by spring when power is off.

Checks
1. The resistance is infinite when the
resistance is measured at both
connector ends with a tester.
2. The resistance significantly very much
when the resistance is measured at both
connector ends with a tester.
1. Remove connector from freezer hinge
and measure the resistance of heater.
