If your air conditioner still does not work properly although you checked the points as described above, first stop the operation and 
turn off the power switch. Then contact your dealer and report the serial number and symptom. Never repair your air conditioner by 
yourself since it is very dangerous for you to do so. You also report if the inspection mark   and the letters E, F, H, L, P in 
combination with the numbers appear on the LCD of the remote controller.
