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

Dose the Buzzer sound, when the power on?

Y

Check whether the "COOLING ICON" LED lamp is on

N

and the operation starts when pressing the on/off

 

 

button of the remocon.

 

Go to the clause "No power".

•Go to the clause "when he remocon does not operate".

Y

Check whether the compressor is activated in three

Y

minutes after turning on the power with the "CoolING

 

ICON" LED lamp being switched on when selecting the

 

 

cool mode of the remocon.

 

 

 

 

Normal operation.

N

Is the IC03 output normal?

- When the compressor is on, IC03 No. 13 pin → Low.

Y

Does the relay(RY71) operate normally?

- When the compressor is ON, the RY71 should operate.

Y

Is the compressor normal?

Y

Replace the compressor.

N

N

N

•Check the IC03 for short and cold soldering.

•Replace the IC03.

•Check the relay coil resistance. (resistance : About 150Ω ±20Ω )

•Replace the relay.

•Check the operation of the O.L.P, and replace it if necessary.

•Check the compressor

resistance.(0Ω : short, ∞Ω : open)
