intervene in rotational area
of fan propeller?
Is DC280V
detected between

Is it normalized?
Is the fuse F3 (F4) or F202
blown?

FDF series
NO
YES
Power supply reset
Remove foreign material.
Replace the fan motor.
Replace the control PCB
Check power voltage.
Replace faulty fan motor
and power PCB.
Replace fan motor. (If the
error persists after replacing
the fan motor, replace the
indoor control PCB.)
Malfunction by temporary
noise
2. Error detection method
Detected by rotation speed of
indoor fan motor
3. Condition of Error displayed
When the actual fan rotation
speed does not reach to the
speed of [required speed
-50rpm] after 2 minutes have
been elapsed since the fan
motor rotation speed command
was output, the unit stops by
detecting indoor fan motor
anomaly.
4. Presumable cause
• Defective indoor power (control)
PCB
• Foreign material at rotational
area of fan propeller
• Defective fan motor
• Dust on control PCB
• Blown fuse
• External noise, surge
Note:
Note (1) Value in
(
