K Check of LEV (Expansion valve)

Press OPERATE/STOP (ON/OFF) button of the remote

controller (the set temperature is displayed) with the

remote controller headed towards the indoor unit. 1

Expansion valve operates in full-opening direction.

NOTE

: After check of LEV, do the undermentioned operations.

1. Turn OFF the power supply and turn ON it again.

2. Press RESET button on the remote controller.

1. Regardless of normal or abnormal condition, a short beep

is emitted once the signal is received.

Measure each voltage between connector

pins of CN724 on the inverter P.C. board.

1. Pin (-) — Pin (+)

2. Pin (-) — Pin (+)

3. Pin (-) — Pin (+)

4. Pin (-) — Pin (+)

Is there about 3 ~ 5 VAC between each?

NOTE

: Measure the voltage by an analog

tester.

Properly

x the LEV coil to the expansion valve.

Replace the inverter P.C.

board.

Replace the LEV coil.

Replace the expansion valve.

Is LEV coil properly

xed to

the expansion valve?

Does the resistance of LEV

coil have the characteristics?

(Refer to 11-4.)

Do you hear the expansion valve "click,

click·······"?

Do you feel the expansion valve vibrate

on touching it ?

Turn ON the power supply.

While pressing both OPERATION SELECT button

and TOO COOL button on the remote controller at the

same time, press RESET button.

First, release RESET button.

Hold down the other two buttons for another 3

seconds. Make sure that the indicators on the LCD

screen shown in the right

gure are all displayed.

Then release the buttons.

Yes

J Check of power supply

Is there voltage 230 VAC

between the indoor terminal

block S1 and S2?

Yes

Replace the indoor

electronic control P.C.

board.

Rectify indoor/outdoor

connecting wire.

Yes

If light up, OK.

ash, refer to 11-3.

Does the upper lamp of OPERATION

INDICATOR lamp on the indoor unit

light up?

Does LED on the inverter P.C.

board light up or

ash? (Refer

to 11-6.1.)

Replace the inverter

P.C. board.

Is there voltage 250 - 370 VDC

between DB61 (+) and DB61 (–) on

the inverter P.C. board?

(Refer to 11-6.1.)

Check the electric parts in main circuit.

Yes

Disconnect the connector (CN61)

between compressor and power

module.

Turn ON power supply and press

EMERGENCY OPERATION switch.

Inverter P.C. board
