Your new ice maker may make some sounds that are not familiar to you. Most of the new sounds are
normal. Hard surfaces like the floor, walls and cabinets can make the sounds seem louder than usual.
The following describes some kinds of sounds that might be strange to you and the reasons causing
them.
You will hear a swooshing sound when the water valve opens to fill the water tank for each cycle.
Rattling noises may come from the flow of the refrigerant or the water in the water line. Items stored
on top of the ice maker can also make noises.
The high-efficiency compressor may make a pulsating or high-pitched sound.
Water running from the water tank to the evaporator plate may make a splashing sound.
Water running from the evaporator to the water tank may make a splashing sound.
As each cycle ends, you may hear a gurgling sound due to the refrigerant flowing in your ice maker.
You may hear air being forced over the condenser by the condenser fan. During the harvest cycle,
you may hear the sound of ice cubes falling into the ice storage bin.
