Troubleshooting
Description of diagnosis
The damper does not rotate
normally. Check for any
foreign matters around the
damper and for the operation
of the gear and limit switch.
The unit has not yet
completed the filter self-
cleaning operation even after
the lapse of specified period
of time. Check for any
external noise, etc.
A combination of indoor unit
PCB and fan PCB is
defective. Check whether the
capacity setting adaptor is
correct and the type of the fan
PCB is correct.
Troubleshooting
Description of diagnosis
The fan motor has caused
abnormal rotation. Check for
the connection of the
connector between the fan
motor and the outdoor unit
PCB. If the connection is
normal, replace the fan
motor. If this still cannot solve
the error, replace the outdoor
unit PCB.
Refer to the "L1" flow chart of
each manual and make a
diagnosis of the relevant unit
based on the Error code
shown to the left.
