This sound happens when the liquid or vapor refrigerant flows from the
evaporator to compressor.
Click ■ Explain the characteristics of moving parts.
• This noise comes from the MICOM controller's switch on the top of the
refrigerator when it is turned on and off.
Noise of Icemaker operation ■ Explain the procedure and principles of Icemaker operation.
(applicable to model with Icemaker). • The automatic icemaker continuously cycles through water supply ➝ icemaking
- Noise produced by ice dropping ➝ ice ejection ➝ repeat. When water is dispensed, the water supply
and hitting ice bin. valve in the mechanical area makes hissing sounds and you can
- Noise from motor sounds Hiss. hear the water flow. When water freezes, you can hear clicking. When ice is
ejected, you can hear the motor run, the tray twist, and ice breaking and falling
into the bin.
Noise when dispensing water. ■ Explain the principles of water supplied to dispenser.

tank in the lower part of the refrigerator compartment. The water is dispensed
by this pressure. When this happens, motor sound and water flowing sound are
heard.
Noise when dispensing ice. ■ Explain the principles of ice supply and procedure of crushed icemaking in a
dispenser.
