Detected by rotation speed of
indoor fan motor
3. Condition of error displayed
• When actual rotation speed of
indoor fan motor drops to lower
-1
than 200min for 30 seconds
continuously, the compressor
and the indoor fan motor stop.
• After 2-seconds, it starts
again automatically, but if this
error occurs 4 times within
60 minutes after the initial
detection.

• Defective fan motor
• Dust on control PCB
• Blown fuse
• External noise, surge
