YES
Replace the outdoor control PCB
NO
YES
YES
NO
Is the
connection of connectors between
the inverter PCB and the outdoor
control PCB OK?
Are both
switches of JSW10,11
on the inverter PCB
set correctly?
Is LED
on the inverter PCB
flashing?
For 3-phase models
Is the
communication wire between the
inverter PCB and the outdoor control
PCB connected properly?
Does it become normal?
YES
NO
NO
NO
For single-phase models
Note(1) How to check
voltage at CN13
→
See E51
Note(2) Under anomalous
conditions, the
voltage becomes
less than DC14V
Is DC15V
detected between
②
and
③
on CNI3?
Is DC15V
detected after disconnecting
outdoor fan motor?
YES
YES
⑴
⑵
NO
Correct the connection.
Set JSW10, 11 correctly
ª
See page from 351 to 353.
No power is supplied to
inverter PCB.
Check the power supply
voltage and correct it
If not solved, find the
cause by checking
following points.
• Fan motor anomaly
Replace outdoor fan motor
Replace outdoor control
PCB if not solved, replace
inverter PCB as well
Connect the
communication wire
securely
Replace inverter PCB
OK
2. Error detection method
When the communication
between inverter PCB and
outdoor control PCB is not
established.
3. Condition of Error displayed
Same as above.
4. Presumable cause
• Inverter PCB anomaly
• Anomalous connection
of connector between the
outdoor control PCB and
inverter PCB
• Outdoor control PCB anomaly
• Outdoor fan motor anomaly
Note:
Communication error between
inverter PCB and outdoor control PCB
