Noise Problem
1.1 When the air conditioner is running, it makes a “thunder bang bang” sound?
Plastic thermal expansion and contraction caused by cold, does not affect the use.
1.2 Why does the air conditioner still make the sound of “card, card” after it is turned off?
This phenomenon occurs not only after shutdown, but also during operation. It is mainly caused by thermal expansion and contraction of plastic parts, and does not affect the use.
1.3 Why does the newly installed machine make noise when swinging?
Because the pendulum shaft of the newly installed machine is too wrinkled just after use, it needs a period of running-in, so you can drop a little lubricating oil on it.
1.4 What sounds does the indoor unit make when the air conditioner is normal?
When the air conditioner is working normally, there are the following sounds: A, the sound of the compressor working normally, if the customer feedbacks that the noise is too loud, it can be set to sleep mode. B. The sound of the wind when the air conditioner is running. At this time, the corresponding wind sound can be improved by adjusting the corresponding wind speed. C. The “cracking” of the plastic parts of the air conditioner as the thermal barrier shrinks. This sound cannot be completely avoided. It can only be adjusted by adjusting the tightness of the shell The position is improved accordingly D, the sound of the refrigerant rapidly vaporizing and liquefying in the pipe.
1.5 Is the indoor unit noisy?
A. There are sundries inside the machine. B. The mounting plate is not hung properly. C. There is friction between the wind wheel and the motor cover.
1.6 The noise of the internal machine is relatively loud half an hour after shutdown (reported by users)?
Liquid slamming is normal.
1.7 Why does the air conditioner make a sound like running water when it is running?
This is due to the sound made by the refrigerant flowing in the refrigeration system, which is a normal phenomenon.
1.8 Why is the result of the decibel meter test higher than the data marked on the machine itself?
The state stipulates that the noise should be measured in the testing room and in the user’s home. Due to various factors such as environmental facilities, the decibel may be a little higher than the standard.
1.9 What are the abnormal noises caused by transportation?
1. If the tube is touched, the tube will be broken (it is recommended to change the machine)
2. Wind wheel scraping
3. The four-way valve is stuck (replacement is recommended)
4. If the goods are not refrigerated just after receiving the goods, they can only be replaced.
