(green)
INDICATION LAMP
check the drain hose by eyes (it might be folded or choked)
check the TAN whether lean or not
not cool down
not warm up
water leakage
louver doesn' t work
※
In this table TAN means indoor unit and TAG 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 (TAN)
check the voltage between blue and yellow in connector [see fig.3]
if it is AC 110V ~ 230V, TAN fan motor should be replaced
check the resistance by tester [see fig.4]
check the blockage of air inlet & outlet of TAN, TAG

※
Take off the connector and check the Resistance of 4-way valve coil.
Take off the connector and check the resistance between
the common terminal and each terminal.
Check the TAN PCB(main)
Measure the voltage between the connector pins in the back
of TAN PCB(main).
