What should I do when the refrigerator makes noise?

Hmm ~~

10 sec. ↓

When operating a refrigerator, it is the noise that occurs when a stopping compressor increases its RPM quickly. 

(E.g. a case similar to the engine noise when starting a car.)

Hmm~

high pitched

2 min. ↓

The noise generated by automatically changing to the RPM of the compressor according to the operating condition.

(set temperature, inside/outside temperature/humidity, etc.)

(E.g. similar to engine fluctuation noise when a car's speed changes.)

Hmm~

high pitched

(Initial installation)

During the first operation of the refrigerator,

the compressor or fan rotates at a high speed to lower the temperature in the refrigerator quickly, and a relatively loud noise appears.

(E.g. when the car is running at high speed, the engine noise is loud.)

Clicking

Continuously

This is the basic operation noise when the compressor internal parts open and close. 

- The tone changes according to the compressor rotation speed.

Pitter-
patter~

(When the compressor is off)

The noise that occurs when the compressor stops spinning at high speed.

- It is similar to front-leaning when the brake is pressed.

When operating a refrigerator, it is the noise that occurs when a stopping compressor increases the RPM quickly.

Hmm~,
beep~

Continuously

Wind noise generated by the fan motor rotating.

- There is a change of rotation speed depending on the operating conditions

(set temperature, inside/outside temperature/humidity, etc.) and the noise changes.

Prrrrrr~
Rip~

Continuously

The noise of the refrigerant spray.

- The noise generated when a refrigerant is injected into a large pipe from a microtubule.

(refrigerator basic cooling principle)

Growl~,

shoo~boiling

Continuously

The noise generated by the refrigerant flowing through the pipes in every corner of the refrigerator.

 - The same principle as the noise of water flowing in the water supply/drainage pipe at home. 

Pop!,
snap!
Rattle!

(momentary

When the temperature inside the refrigerator is changed, it is the noise generated by the internal compressor as it expands and shrinks.

 (E.g. similar to the noise of the car hood such as ting! when the car is turned off.)

Clitter~

(When defrosting)

It is the noise wherein the frost melt falls when defrosting the cooler. 

- Cooling performance is improved when frost is removed.

Ting!,
ting!

30 min. ↓

(When defrosting)

It is a noise generated when the frost is defrosted by the internal heater.

(E.g. the noise of cold dripping water in hot pans.)

Swish~

Door 

Open/Close

The noise of wind blowing to defrost the water hose.

- When the refrigerator door is opened and closed, the air flows out to/from the refrigerator. (To improve the door opening force) 

(E.g. a room door closes easier if a window is open. Wind noises occur between the windows.)

Rattle~

(periodically)

It is a valve operation noise that supplies refrigerant to a part where cooling is required for maintaining a precise temperature in every room.

 (E.g. the same principle as gas valve adjustment for fire control.)
