(6) Inspection procedures corresponding to detail of trouble Sensor error Is connector connection good? YES Is sensor resistance value good? (Broken wire) 30 (Short circuit) YES Replace PCB. NO NO ◆ Sensor temperature characteristics (Room temp., indoor heat exchanger temp.) Resistance (kΩ) 25 20 15 10 5 -10 0 10 20 30 40 50 60 70 Temperature (˚C) Indoor fan motor error Is connector connection good? YES Is the output of the indoor unit PCB normal? Power source reset Is normal state restored? YES Malfunction by temporary noise NO NO NO '15 • SRK-T-171 [Broken sensor wire, connector poor connection] [Defective fan motor, connector poor connection, defective indoor PCB] - 64 - Correct connection. Replace sensor. Correct connector connection Replace indoor PCB Replace fan motor (If anomaly persiste after replacing fan motor, replace indoor PCB)

'15 • SRK-T-171 [Compressor malfunction of Trouble of outdoor unit insufficient gas (refrigerant)] Does compressor operation? NO Is capacitor for compressor normal? NO Replace capacitor for compressor. YES Is connector for compressor connection NO good? Correct connection YES Replace compressor. YES Is refrigerant amount normal? NO NO Check if there are any places where Does trouble persist after charging gas? gas is leaking YES YES Clogged capillary tube or strainer, etc. Insufficient gas (7) Phenomenon observed after shortcircuit, wire breakage on sensor (a) Indoor unit Sensor Operation Phenomenon mode Shortcircuit Broken wire Room temperature Continuous compressor operation command is not released. sensor Cooling Release of continuous compressor operation command (Room temperature sensor error.) Heat exchanger Continuous compressor operation command is not released. Cooling System can be operated normally. sensor (Anti-frosting, heat exchanger sensor error.) (8) Checking the indoor electrical equipment (a) Indoor PCB check procedure Is there voltage at power source? NO (AC 220/230/240V) Inspect power source. YES Is the fuse burnt out? (3.15 A) YES If the package components are not damaged, replace the fuse and perform an operation NO check again. Replace PCB
