Troubleshooting

■ Title

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



■ Problem

Noise/Vibration



■ Symptom

  ‘Brrr’   noise from the indoor unit



■ Possible Cause

■ 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.
