This product is designed so that, after a power failure, it can restart automatically in the same operating mode as before the power failure.

INFORMATION

The product was shipped with Auto Restart function in the off position. Turn it on as required.

* See detail in section 7-7. Auto Restart Function

9. TROUBLESHOOTING CHART

TROUBLESHOOTING PROCEDURES :

• Following details of "What to be pre-checked first", make sure of the basic items.
• When there is no trouble corresponding to above, check in detail the faulty parts following “How to judge faulty parts by symptoms” later.

9-1. What to be Prechecked First

9-1-1. Power Supply Voltage

The line voltage must be AC 220–240V (220V for RAS-07YKX-T, RAS-10YKX-T).

If the line voltage is not within this range, this air conditioner may not work normally.

9-1-2. Incorrect Cable Connection between Indoor and Outdoor Units

The indoor unit is connected to the outdoor unit with 3 cables. Make certain that the indoor and outdoor units have been connected properly, with terminals assigned the same numbers wired to each other. If the connectors are not connected as specified, the outdoor unit will not operate normally.

9-1-3. Misleading but Good Operations (Program Controlled Operation)

The microcomputer performs the operations listed in Table 9-1-1 to control the air conditioner. If a claim is made on the operation, check whether it corresponds to the contents in the Table 9-1-1. If it does, it is an indispensable operation for the control and maintenance of the air conditioner: it is not a failure of the unit.

Table 9-1-1

No.	Operation of air conditioner Description
1	When the power plug or the power cord of the indoor unit is inserted, the OPERATION lamp on the setting indication part blinks.	The OPERATION lamp blinks, indicating that power is turned on.If this happens, push the START/STOP button once to cause the lamp to stop blinking. A power outage also causes the lamp to blink.
2	Fan speed remains unchanged in the dry mode.	Fan speed is automatically controlled in the dry mode.
3	The compressor will not switch on or off even when the thermo. control is operated in the dry operation.	In the dry mode, the compressor goes on and off at regular intervals, independent of the thermo. control.
4	Compressor does not work though room temperature is in the range of turning the compressor on.	Compressor does not work while the compressor restart delay (3-min.) timer is active. The same is true after power is turned on, as the time is still active.
5	During automatic operation, the operation mode changes.	After selection of the cooling and dry operation, the operation mode is selected again when the compressor off mode continues for 15 min. according to the room temperature. And after selection of the dry operation, the condition of the room temperature which is Room temp.≥Set temp.+1 and which is Room temp.<Set temp.-4 continues for 15 min., the operation mode is selected again.
6	When the power is turned on, the operation starts automatically.	When the auto restart controlling is selected, the operation is performed automatically in the previous operation mode after the power supply has been turned on.

9-2. Primary Judgement of Trouble Sources

9-2-1. Role of Indoor Unit Controller

The indoor unit controller receives the operation commands from the remote control and assumes the following functions.

• Measurement of the draft air temperature of the indoor heat exchanger by using the thermo sensor (TA).
• Louver motor control
  • Control of the indoor fan motor operation
  • Control of the LED display
• Control of the outdoor unit compressor and the outdoor fan motor.

9-2-2. Display of Abnormalities and Judgement of the Abnormal Spots

The indoor unit of this machine observes the operation condition of the air conditioner and displays the contents of the self-diagnosis as block displays on the display panel of the indoor unit.

Table 9-2-1

	Block display Description
A	OPERATION display blinking (1 Hz) Power failure (when power is ON)
B	OPERATION display blinking (5 Hz) Thermo. sensor (TA) short/break
C	OPERATION display blinking (5 Hz)	Heat exchanger sensor (TC) short/break
D	OPERATION display blinking (5 Hz) Indoor fan lock, abnormality of indoor fan
E	OPERATION display blinking (5 Hz) Indoor P.C. board failure
F	OPERATION, TIMER and FAN-ONLY display blinking (5 Hz)	Gas shortage, other refrigerant cycle troubleHeat exchanger sensor open/break/shortOverload relay trouble

(1) Judgement from defective operation or abnormal operation

Table 9-2-2

Symptom Check	Primary judgement
No reaction on remote control operation	Turn off the power once, turn it on again and try to operate the remote control again.	Remote control is not possible.	The indoor part (including the remote control) is defective.
		Remote control is possible. OK.
The outdoor fan does not rotate	The compressor operates.		The outdoor part is defective. (outdoor fan motor)
	The compressor does not operate. The inside part is defective.

(2) Self-diagnosis with remote control

With the indoor unit control, self-diagnosis of protective circuit action can be done by turning the remote control operation into service mode, operating the remote control, observing the remote control indicators and checking whether TIMER lamp blinks (5 Hz).
