Does the air cooler not produce enough air, resulting in low airflow?

    1. Check if the wind feels like it's being sucked in. If there is wind on the opposite side, it may be due to the wrong wiring of the fan 

motor. You can adjust the contact wire of the motor to solve the problem, which can take about 10-30 to fix.

    2. It is possible that the rotary shaft under the control panel is blocking the air outlet and breaking. Find a master or seal it with glue

yourself.

    3. The fan is faulty or not, and it is a problem with the motor itself. This is a bit troublesome, we need to replace the motor.

Does the air cooler can't cool down?

    1. Check if the ice curtain is wet. If it is tilted or not installed properly, this phenomenon can also occur.

    2. Check if the water pump is working. If it is not pumping, first check if the circuit is disconnected. A. If the circuit is complete, it can 

be determined that there is a problem with the water pump. B. If the circuit is disconnected, the connection line can be determined.

    3. Normally, you can wet the ice curtain with ice water before installation, which will improve the ventilation effect.

Does the air cooler leaking water?

    1. Check the water tank to see if it is damaged.

    2. Check the water pump to see if the rubber hose on the pump is damaged or if the interface is not properly installed. You can replace 

or wrap the interface to solve the problem.

    3. Another possibility is that the bracket of the sink breaks, causing the sink to tilt and leak water. If this is crooked, you can use 502 

to fix the bracket and see if it's okay. Generally speaking, it works, just compensate a little bit.

    4. The ice curtain was not installed properly, and water dripped down the sink hole and splashed along the ice curtain onto the back 

cover of the air conditioning fan, accumulating water droplets. Installing correctly can solve the problem.

    5. Many air conditioning fans have no water tank, and the bottom shell is directly connected to the universal wheel. Many leaks are 

caused by the leakage at the bottom universal wheel. You can check if the universal joint is damaged, and it can be blocked with glue or 

ordinary waterproof tape.

    6. The bottom plug was not installed properly, causing water leakage.

Does the air cooler wind blade can’t swing?

    1. Check the layout to see if it is not properly installed and then reinstall it. It is also possible that the page is stuck, which is less 

common. There are also damaged fan blades that cannot swing, so manually adjust the direction of the air outlet.

    2. If the wire controlling the swing motor is lost or the swing motor is broken, just find a technician to check it. The cost is not high. 

If the swing motor is broken, you can send it back or open the back cover and check according to the internal diagram.

Does the air cooler making high noise level?

    1. Because the air outlet is relatively large, there are also internal air outlets that produce sound when the wind turbine rotates, which 

is a normal phenomenon.

    2. Check if the wind turbine has inhaled hair or other debris, open the back cover and clean it up

    3. Check if the wind turbine shaft is broken. If it is not, add lubricating oil to solve the problem.
