What can we do if Air-Flow Blade is not working properly in Air-Conditioner?

There are some basic steps you can follow to resolve your problem of Samsung Air Conditioner as mentioned below : 

● Please check if the Swing button in remote controller is ON/OFF. The blade should move up and down, about 43° each time when the ON button is activated.

● If there is no response from the system after the Swing button is activated, it is likely the Stepper Motor that controls the blade is faulty.

● You have to get the Stepper motor replaced by  contacting your nearest Samsung Service center or you can visit the below mentioned link.
