6. Troubleshooting
6-1 Items to be checked first
1. The input voltage should be rating voltage ±10% range.
The airconditioner may not operate properly if the voltage is out of this range.
2. Is the link cable linking the indoor unit and the outdoor unit linked properly?
The indoor unit and the outdoor unit shall be linked by 4 cables.
Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.
Otherwise the airconditioner 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
airconditioner.
No
Operation of air conditioner
Explanation
1
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 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 compressor 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
2
Fan speed setting is not allowed in AUTO(
DRY(
) mode.
The speed of the indoor fan is set to LL in DRY mode.
Fan speed is 5 steps is selected automatically in AUTO mode.
3
Compressor stops operation intermittently in
DRY(
) mode.
Compressor operation is controlled automatically in DRY mode
depending on the room temperature and humidity.
4
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 continues operation for up to 10 minutes (maximum)
until the deice is completed.
5
Timer LED(
) only 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 operation is cancelled.
6
The compressor and indoor fan stop intermittently in
HEAT mode.
The compressor and indoor fan stop intermittently if room
temperature exceeds a setting temperature in order to protect
the compressor from overheated air in a HEAT mode.
7
Indoor fan and outdoor fan stop operation
intermittently in a HEAT mode.
The compressor operates in a reverse cycle to remove
exterior ice in a HEAT mode, and indoor fan and outdoor fan
do not operate intermittently for within 20% of the total heater
operation.
8
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 temperature.

6-4 PCB Inspection
6-4-1 Cautions for Part Replacement
1.
The human body carries much static electricity. Before
touching a part for repair, replacement or the similar
purpose, be sure to touch a grounded metallic portion by
hand to let the static electricity go through the metallic
portion to the earth.
Especially when handling any micro computer or IC,
carefully remove such static electricity before touching
them.
2.
When repairing any part on a work bench, be sure to
place an insulative sheet on the bench and always keep
the sheet surface neat without any metal fragments.
If any such fragment touches a part, a secondary trouble
will possibly be caused in the part.
3.
Before replacing any parts, be sure to turn off the power
supply. If such replacement is done with the power supply
kept on, an electric shock, short circuit or destruction of a
part may result.
4.
During replacement or repair of a part, carefully handle it
: The printed circuit board has fine lead wires (jumper
wires) and glass-made parts (diode) on its substrate.
So if a circuit board is roughly handled, such
lead wires and parts will be easily broken or damaged by
bending or shock.
5.
When soldering the lead wires of any new part, be sure
to polish them using an emery paper or the like before
soldering them.
Since the lead wires of any new part are covered with an
oxide film, solder cannot adhere to the lead wires if not
polished.
6.
When soldering any part, care should be exercised not to
apply any high-wattage soldering iron to the part for a
long time. Some parts are of so low a heat resistance
that they may be broken or have the properties changed
if a soldering iron is so applied (Otherwise, the pattern
may possibly be separated and raised).
7.
The heat of the soldering iron should be transferred to
the entire object to be soldered. If the solder pieces are
not well fused due to insufficient transfer of the heat from
the soldering iron, no satisfactory electrical continuity can
be assured even if the soldered objects appear well connected to each other.
8.
The solder used should be limited to a minimum.
If excessive solder is used, it will cause inter-pattern
contact, which may cause malfunction of the circuit.
6-4-2 Procedure
The parts should be replaced in the following procedure.
Check for any faulty part.
Detach the faulty part.
Replace it with a new part.
Check the operation of the new part.
The repair is completed.
