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 A C 220/230/240V. 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 5 cables. Mak e 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, or OPERATION lamp and TIMER lamp will blink (5Hz).

– 39 –

No.

Operation of air-conditioner

When the power plug or the power cord of the indoor unit is inserted, the OPERATION lamp on the setting indication part blinks.

Fan speed remains unchanged in the dry mode.

Room temperature is in the range under which the compressor is turned off, but the compressor will not stop.

The compressor will not switch on or off even when the thermo. control is operated in the dry operation.

The PRE-DEF. lamp comes on when the heating operation is started.

The outdoor fan stops once in the while during the heating operation.

Compressor does not work though room temperature is in the range of turning the compressor on.

During automatic operation, the operation mode changes.

During automatic operation mode, the fan only operation continues.

When the power is turned on, the operation starts automatically.

Description

The OPERATION lamp blinks, indicating that pow er 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.

Fan speed is automatically controlled in the dry mode.

The compressor will not stop while the compressor on hold timer (3-minutes timer) is actuated.

In the dry mode, the compressor goes on and off at regular intervals, independent of the thermo. control.

The PRE-DEF. lamp comes on during defrost operation and when the indoor heat exchanger temperature is low when the heating operation is started. At this time, the indoor fan is stopped to prevent cold air from drifting into the room.

• When the indoor heat exchanger temperature is high, the outdoor fan may be stopped b y the high-temperature limit control operation.

• When the compressor current is large, the outdoor fan ma y be stopped by the current limit control operation.

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.

After selection of the cooling and heating operation, the operation mode is selected again when the compressor off mode continues for 15min. according to the room temperature.

When the room temperature is within setting temperature ± 1°C the fan only mode is selected.

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.
