2) Gear Box Application Type
Gear box is used for moving and crushing ice which is
stored in the ice bin. Gear box is connected at the output
axis of shaded motor. Gear box changes high RPM of
motor to low RPM but high power by gear box. This power
can move and crush ice.

6. Solenoid.
1. Structure of Solenoid
Two types of solenoids are used for refrigerator depending
on the applications such as solenoids for ice cube and ice
dispenser. The solenoid is composed of an armature,
stator and a main body which supports stator and pulls the
armature when electricity is applied.
2. Operation Principles
When electricity is applied to the coil, magnetic field forms
around the coil. The armature in the magnetic field moves
toward the stator and ice dispenses. When electricity is
removed, the armature moves back to its original position
(rated stroke distance) by the spring force and stops
moving.

CAUTIONS : • Do not operate solenoid for more than two
minutes. It may be overheat.
• Solenoid is not for continuous use but
discontinuous use as it operates when
customer dispenses ice.
