Description of error
Troubleshooting
Description of diagnosis
Refer to page 217.
A locked fan motor current has been detected.
Turn the fan by hand to check for the connection of connectors.
A fan motor overcurrent has been detected.
Check for the connection of the connector between the fan
motor and the fan PCB. If the connection is normal, replace the
fan motor. If this still cannot solve the error, replace the fan
PCB.
An error in the detection of position of the fan motor. Check for
the connection of the connector between the fan motor and the
fan PCB. If the connection is normal, replace the fan motor. If
this still cannot solve the error, replace the fan PCB.
Refer to page 228.
Refer to page 229.
Check for the input voltage of the fan motor.
There is an error in the electronic expansion valve coil or a
connector disconnected.
Refrigerant leaks even if the electronic expansion valve is
closed.
Replace the electronic expansion valve.
Check for the connection of the harness connector between the
panel PCB and the indoor unit PCB.
Check for the connections of the connector X12A on the panel
PCB and the connectors X18A and X19A on the sensor PCB.
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.
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).
The damper does not rotate normally. Check for any foreign
matter around the damper and for the operation of the gear and
limit switch.
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.
The unit has been put into a state in which the filter
self-cleaning operation is disabled. Check the unit for the
operating conditions.
There is an error in the capacity setting of the indoor unit PCB.
There is a fault in the setting of the gear type electronic
expansion valve/direct acting type electronic expansion valve.
Check for the conditions of transmission between the indoor
unit PCB and the fan PCB.
Refer to page 240.
A combination of indoor unit PCB and the fan PCB is defective.
Check whether the capacity setting adaptor is correct and the
type of the fan PCB is correct.
Refer to page 243.
Refer to page 244.
