SiAF332111E Troubleshooting by Error Code
Part 6 Service Diagnosis 193
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
As there are various combinations of indoor and outdoor units, the sub codes of A0 - A3 are not
shown in this table.
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 - 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
CE - 02
Infrared floor sensor error A disconnection of the temperature correction circuit
(thermistor) of the infrared floor sensor has been detected.
Check if the connector is properly connected.
CE - 03
Infrared floor sensor error A short-circuit of the temperature correction circuit (thermistor) of the
infrared floor sensor has been detected. Check if the pins of the
connector are touching each other, and if any foreign matter on the
PCB is causing a short-circuit.
CE - 04
Infrared floor sensor error An abnormality other than the ones mentioned above has been
detected.
Check if the temperature nearby the sensor is too high, and if there is
any foreign matter that may cause noise.
U4 - 01 Indoor-Outdoor transmission error Refer to the U4 flowchart.
UA - 13
Refrigerant type error The type of refrigerant used for the indoor unit is different from that
used for the outdoor unit.
UA - 15
Not applicable for self-cleaning decoration
panel (when the self-cleaning decoration
panel is mounted)
An outdoor unit is not applicable for the self-cleaning decoration panel
is connected.
