Communication error between
inverter PCB and outdoor control PCB
Keeps flashing
Stays Off
Keeps flashing 1 time flash
1. Applicable model
5. Troubleshooting
Outdoor unit
Diagnosis
Countermeasure
Is 15V
of power for control PCB
detected? Is the outdoor fan motor OK?
(Refer the checking method of 15V
in page 41)
Turn off the power.
IS the harness and/or
connector between inverter
PCB and outdoor control
PCB OK ?
Is the rush
current prevention resistor
broken?
Is the
harness and/or connector
between
inverter PCB and diode module
OK?
Is the
setting of switches on the inverter
PCB OK? *
Reset power supply and restart

Check and save the data of
operating conditions
Replace inverter PCB or
outdoor fan motor
Check it as much as
possible under the operating
conditions for 30 minutes
before error occurred
Wait and see.
Continue to obain data, if
possible (Keep connecting
the Mente PC)
Check whether the harness
is broken?
Check whether the
connector is loose?
If there is problem,
correct it.
Disconnect the harness
from the resistor and
measure the resistance.
If broken, replace the
resistor.
In such case check the
harness between diode
module and inverter PCB
as well
Check whether the harness
is broken?
Check whether the
connector is loose?
If there is problem,
correct it.
Correct the setting of
switches on the inverter
PCB
Replace outdoor control
PCB
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
• Signal wire anomaly
• Outdoor control PCB
anomaly
• Inverter PCB (INV1)
anomaly
• Rush current prevention
resistor anomaly
Note: If the error does not recur, connect the Mente PC and continue to collect data.
