1. Precautions
1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.
2. Use proper parts: Use only exact replacement parts. (Also, we recommend replacing
parts rather than repairing them.)
3. Use the proper tools: Use the proper tools
and test equipment, and know how to use
them. Using defective tools or test equipment may cause problems later-intermittent
contact, for example.
Fig. 1-1 Avoid Dangerous Contact
4. Power Cord: Prior to repair, check the
power cord and replace it if necessary.
5. Avoid using an extension cord, and avoid
tapping into a power cord. This practice
may result in malfunction or fire.
6. After completing repairs and reassembly,
check the insulation resistance.
Procedure: Prior to applying power, measure the resistance between the power cord
and the ground terminal. The resistance
must be greater than 30 megaohms.
Fig. 1-2 No Tapping and No Extension Cords
7. Make sure that the grounds are adequate.
8. Make sure that the installation conditions
are satisfactory.
Relocate the unit if necessary.
9. Keep children away from the unit while it is
being repaired.
10. Be sure to clean the unit and its surrounding area.

5. Troubleshooting
5-1 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 7 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
The STD operation indication LED blinks when a
power plug of the indoor unit is plugged in for the first time.
It indicates power is on. The LED stops blinking if the operation
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 IN DOOR 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
3
Fan speed setting is not allowed in AUTO or 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.
4
Compressor stops operation intermittently in DRY mode.
Compressor operation is controlled automatically in DRY mode
depending on the room temperature and humidity.
5
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 9 minutes (maximum) until the deice is
completed.
6
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.
7
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.
8
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
9
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.
4)
Indoor unit observes operation condition of the air conditioner, and displays self diagnosis details on the
display panel.

5-4 PCB Inspection
5-4-1 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 solding 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
transfered 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.
5-4-2 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.
