Part 6 Service Diagnosis
5.2 Error Codes (Sub Codes)
If an error code like the one shown below is displayed when the navigation remote controller
(BRC1E series) is in use, make a detailed diagnosis or a diagnosis of the relevant unit referring
to the attached list of detailed error codes.
5.2.1 Indoor Unit
Error code
Troubleshooting
Description of error
Diagnosis
A6 - 01
Fan motor locked
A locked fan motor current has been detected.
Turn the fan by hand to check for the connection of
connectors.
A6 - 10
Fan overcurrent error
A fan motor overcurrent has been detected.
Check for the connection of the connector between the
fan motor and the PCB for the fan. If the connection is
normal, replace the fan motor. If this still cannot solve the
error, replace the PCB for the fan.
A6 - 11
Fan position detection error
An error in the detection of position of the fan motor.
Check for the connection of the connector between the
fan motor and the PCB for the fan. If the connection is
normal, replace the fan motor. If this still cannot solve the
error, replace the PCB for the fan.
A8 - 01
Power supply voltage error
Check for the input voltage of the fan motor.
A9 - 01
Electronic expansion valve error
There is an error in the electronic expansion valve coil or
a connector disconnected.
A9 - 02
Refrigerant leakage detection error
Refrigerant leaks even if the electronic expansion valve is
closed. Replace the electronic expansion valve.
AH - 03
Transmission error (between the self-cleaning decoration
panel and the indoor unit)
(when the self-cleaning decoration panel is mounted)
Check for the connection of the harness connector
between the panel PCB and the indoor unit PCB.
AH - 04
Dust detection sensor error
(when the self-cleaning decoration panel is mounted)
Check for the connections of the connector X12A on the
panel PCB and the connectors X18A and X19A on the
sensor PCB.
AH - 05
Dust collection sign error
(when the self-cleaning decoration panel is mounted)
Check for clogging with dust at the dust collection port as
well as in the brush unit, S-shaped pipe, and dust box.
Furthermore, check for any stains of the light receiving
and emitting parts of the infrared unit.
AH - 06
Air filter rotation error
(when the self-cleaning decoration panel is mounted)
Check for anything getting in the way of rotating the filter
(e.g. the filter comes off or the drive gear is clogged with
foreign matter).
AH - 07
Damper rotation error
(when the self-cleaning decoration panel is mounted)
The damper does not rotate normally. Check for any
foreign matter around the damper and for the operation of
the gear and limit switch.
AH - 08
Filter self-cleaning operation error
(when the self-cleaning decoration panel is mounted)
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.
AH - 09
Filter self-cleaning operation start disabled error (when
the self-cleaning decoration panel is mounted)
The unit has been put into a state in which the filter self-
cleaning operation is disabled. Check the unit for the
operating conditions.
AH - 12
Auto grille unit error
(when the auto grille unit is mounted)
It is detected that the grille does not operate properly.
Check whether the grille does not contact with something
or the wire does not snaggle.
AJ - 01
Capacity setting error
There is an error in the capacity setting of the indoor unit
PCB.
AJ - 02
Electronic expansion valve setting error
There is a fault in the setting of the gear type electronic
expansion valve/direct acting type electronic expansion
valve.
C1 - 01
Transmission error (between indoor unit PCB and the
PCB for the fan)
Check for the conditions of transmission between the
indoor unit PCB and the PCB for the fan.
C1 - 06
Transmission error (between indoor unit PCB
and auto grille control PCB)
Refer to
C1-06
flowchart.
C6 - 01
Defective combination of indoor unit PCB and the PCB for
the fan
A combination of indoor unit PCB and the PCB for the fan
is defective. Check whether the capacity setting adaptor
is correct and the type of the PCB for the fan is correct.
C6 - 05
Indoor unit PCB abnormality
Refer to
C6-05
flowchart.
CE - 01
Infrared presence sensor error
The output of the infrared presence sensor is not
detected.
Check if the connector is properly connected, and if the
harness is not broken.
