10. Troubleshooting
10-1 Ite m s to be checked first
1. The input voltage should be rating voltage
±
10 range.
The air conditioner may not operate properly if the voltage is out of this range.
2. Is the line cable linking the indoor unit and the outdoor unit linked properly?
The indoor unit and the outdoor unit shall be linked by 5 cables.
Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.
Otherwise the air conditioner may not operate properly.
3. When a problem occurs due to the contents illustrated in the table below it is a symptom not related to the malfunction
of the air conditioner.
NO Operation of air conditioner Eplanation
1
The OPERATION indication LED(BLUE) blinks when a
power plug of the indoor unit is plugged in for first
time.
It indicates power is on. The LED stops blinking if the oper-
ation ON/OFF button on the remote control unit is pushed.
2
In a COOL operation mode, the compressor does not
operate at a room temperature higher than the setting
temperature that the INDOOR FAN should operate.
[ In case of heat pu m p m odel ]
In a HEAT operation mode, the compressor does not
operate at a room temperature lower than the setting
temperature that indoor fan should operate.
In happens after a delay of 3 minutes when the compres-
sor is reoperated. The same phenomenon occurs when
a power is on. As a phenomenon that the compressor is
reoperated after a delay of 3 minutes, the indoor fan is
adjusted automatically with reference to a temperature of
the air blew.
3 Fan speed setting is not allowed in DRY mode.
The speed of the indoor fan is set to LL in DRY mode.
Fan speed is selected automatically in AUTO mode.
4
Compressor stops operation intermittently in Dry
mode. Compressor operation is controlled automatically in DRY
mode depending on the room temperature and humidity.
5
Timer LED(ORANGE) of the indoor unit lights up and
the air conditioner does not operate.
Timer is being activated and the unit is in ready
mode. The unit operates normally if the timer opera-
tion is cancelled.
6
The compressor stops intermittently in a COOL
mode or DRY mode, and fan speed of the indoor unit
decreases.
The compressor stops intermittently or the fan speed
of the indoor unit decreases to prevent inside/outside
air frozen depending on the inside/outside air tem-
perature.
7
[In case of heat pu m p m odel]
Compressor of the outdoor unit is operating although
it is turned off in a HEAT mode.
When the unit is turned off while de-ice is activated,
the compressor continus operation for up to 9
minutes(ma
x imum) until the deice is completed.
8
[In case of heat pu m p m odel]
The compressor and indoor fan stop intermittenly in
HEAT mode.
The compressor and indoor fan stop intermittently if
room temperature e
x ceeds a setting temperature in
order to protect the compressor from overheated air
in a HEAT mode.
9
[In case of heat pu m p m odel]
Indoor fan and outdoor fan stop operation
intermittently in a HEAT mode.
The compressor operates in a reverse cycle to remove
e
x terior ice in a HEAT mode, and indoor fan and out-
door fan do not operate intermittently for within 20
of the total heater operation.
