SEEMED WRONG
METHOD OF CHECK
(press the ON/OFF button of remote controller in case of reset)
ELECT

(yellow)
OPERATE
(green)
INDICATION LAMP
check the drain hose by eyes (it might be folded or choked)
check the RC whether lean or not
not cool down
not warm up
water leakage
louver doesn' t work
※
In this table RC means indoor unit and AE means outdoor unit.
check the resistance by tester [see fig.5]
check the point of leakage measure the pressure of compressor
during fixed operation (emergency and test operation)
nasty smell
FILTER IS CHOKED
NO USE FOR A LONG TIME
NASTY SMELL
(CIGARETTE, FURNITURE, ETC.)
DRAINAGE
MIS-INSTALLATION
LOUVER MOTOR
GAS LEAKAGE
SENSOR, TEMP. ROOM
SENSOR, TEMP. HEAT EXCHANGER
4-WAY VALVE
SHORT CYCLE
(INSUFFICIENT AIR CIRCULATION)
check by eyes and clean it
use deodorizer
check the resistance by tester [see table 1]

FAN MOTOR (RC)
check the voltage between blue and yellow in connector [see fig.3]
if it is AC 110V ~ 230V, RC fan motor should be replaced
check the resistance by tester [see fig.4]
check the blockage of air inlet & outlet of RC, AE
