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
equipment may cause problems laterintermittent contact, for example.
4. Power Cord: Prior to repair, check the
power cord and replace it if necessary.
Fig. 1-1 Avoid Dangerous Contact
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.
7. Make sure that the grounds are adequate.
Fig. 1-2 No Tapping and No Extension Cords
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
Check the basic checkpoints first to determine whether it is machine trouble or a problem
in the operation method. When it is not related to the basic checkpoints, perform checking
in accordance with the procedures of troubleshooting by symptom.
5-1 Basic Checkpoints for Troubleshooting
1) Is the voltage of the power source appropriate ?
(1) It should be within the rating voltage ±10% range.
(2) The air conditioner may not operate properly when the voltage is out of this range.
2) Is the connection with the fan motor, compressor wire, and starting condenser
appropriately made ?
3) The symptoms listed in the table below are not indicative of machine trouble.
Symptom
Cause and check
No operation
• Check whether there is power failure or the power plug is pulled out.
• Check whether the unit is stopped as a result of completion
of the sleep time.
• Pull out the power plug for ten seconds, and then insert it again.
Air flows, but
no cooling
• Check whether the Air filter is clogged with dust or is dirty.
• Check whether the desired temperature is too high. Set the desired
temperature to a lower level than the current temperature.
• Check whether it is in "FAN" mode.
The remocon does

Troubleshooting
5-2-4 When the compressor is not operated
1) Check points
(1) Is the voltage of the power source normal ? (the rating voltage ±10% range. )
(2) Is the desired temperature lower than the indoor temperature in the “COOL” mode?
(Compressor stopped)
(3) Is the starting condenser in good contact?
(4) Is the electric wire in good contact ? (CN71, RY71)
(5) Is the output voltage of the IC01(KA7812) and IC02(KA7805) normal ?
Turn off the power, and then turn it on again five
seconds later.
N
Go to the clause "No power".
Dose the Buzzer sound, when the power on?
Y
Check whether the "COOLING ICON" LED lamp is on
and the operation starts when pressing the on/off
button of the remocon.
N
• Go to the clause "when the remocon
does not operate".
Y
Check whether the compressor is activated in three
minutes after turning on the power with the "CoolING
ICON" LED lamp being switched on when selecting the
cool mode of the remocon.
Y
Normal operation.
N
Is the IC03 output normal?
- When the compressor is on, IC03
No. 11 pin → Low.
N
• Check the IC03 for short and cold
soldering.
• Replace the IC03.
N
• Check the relay coil resistance.
(resistance : About 150Ω±20Ω)
• Replace the relay.
Y
Does the relay(RY71) operate normally?
- When the compressor is ON, the RY71 should operate.
Y
N
Is the compressor normal?
Y
• Check the operation of the O.L.P,
and replace it if necessary.
