The air conditioner makes a ‘cracking and breaking’ sound.

Troubleshooting

■ Title

The air conditioner makes a ‘cracking and breaking’ sound.



■ Problem

Noise/Vibration



■ Symptom

 ‘Brrr’ noise from the indoor unit



■ Possible Cause

Cracking and breaking sound of the appliance may occur during the initial operation as the parts and components that adjust the wind direction (up/down/left/right)

  are moving to set the angle and location according to the operation mode.



■ Solution or Settings          


▶ Related Example                                                                                                                                                                            

You can hear the cracking sound from the joints when you move your body without warming-up.                               

However once we start moving the body parts, the sound discontinues and the movement gets much smoother!


▶ Check list


Check if any protective plastic cover or foreign substance is trapped where the louver or components are.

   You may hear a noise if foreign substances are stuck in between.

   Remove the foreign substances.


                                                                         


■ Summary

Cracking and breaking sound of the appliance may occur during the initial operation as the parts and components that adjust the wind direction (up/down/left/right)

   are moving to set the angle and location according to the operation mode.

  The sound reduces as the air conditioner continues to operate.
