Detective details:

Forecast of Cause:

Indicate or Display:

Refer to error code table.

YES

Serial Communication Error

(Serial Forward Transfer Error)

Indoor unit Controller PCB

Indoor unit Fan motor

Outdoor unit Main PCB

1. Connection failure 2. External cause 3. Controller PCB failure 4. Indoor unit fan motor failure

5. Outdoor unit Main PCB

Check Point 1-1 : Reset the power and operate

Does error indication reappear?

Check Point 1-2 :

Check external cause such as noise

Check if the ground connection is proper.

Check if there is any equipment that causes harmonic wave

near the power cable (Neon light bulb or any electronic

equipment which causes harmonic wave).

Check Point 2 : Check connection

Check any loose or removed connection line of

between indoor unit and outdoor unit.

>> If there is an abnormal condition, correct it by

referring to Installation Manual or Data &

Technical Manual.

Check connection condition in control unit.

(If there is loose connector, open cable or mis-wiring)

Check Point 3 : Check the voltage of power supply

Check the voltage of power supply

>> Check if AC216V(AC240V-10%) - 264V(10%) appears

at outdoor unit terminal L - N.

Check Point 4 : Check serial signal (Forward transfer signal)

Check serial signal (Forward transfer signal)

>> Check if indicated value swings between AC30V and AC130V at outdoor unit terminal 2 - 3.

>> If it is abnormal, replace Controller PCB.

>> If it is abnormal, Check Indoor unit fan motor. (PARTS INFORMATION 4)

>> If Indoor unit fan motor is abnormal, replace Indoor unit fan motor and Controller PCB.

>> If it is abnormal, replace Outdoor unit Main PCB.

When the outdoor unit cannot properly receive the serial signal from

indoor unit for 10 seconds or more.
