Model
Note (1) “None” means that jumper wire is
not provided on the PCB or the
connection is cut.
(c) Error diagnosis procedures at the outdoor unit side
At the error diagnosis related to the outdoor unit, check at first the error code of remote controller and the illumination
patterns of norma l and inspection display lamps in the same manner as the case of indoor unit.
Then estimate the outline, the cause and the location of error based on the pattern and proceed to the inspection and repair.
Since the self diagnosis function by means of the microcomputers of indoor/outdoor units provide the judgement of error of
microcomputers them selves irregularity power supply line, overload, etc. caused by the installation space, inadequate volume
of refrigerant etc., the location and cause of trouble will be discovered without difficulty.
In addition, the display lamps error code of indoor/outdoor units is kept flashing, (except when the power supply is
interrupted)after the irregularity is automatically recovered to give irregularity information to the service presonnel. If any
mode of higher priority than the error retained in memory occurs after the reset of error, it is switched to that mode and saved
in the memory.
(i) Replacement parts assembly related to the outdoor unit PCB
Outdoor unit PCB, outdoor unit inverter PCB, power transistor module, diode module, capacitor, reactor, noise filter,
thermistor, (heat exchanger, discharge pipe, outdoor temperature), fuse, transformer, etc.
(ii) Parts layout on the outdoor unit PCB
