14. Troubleshooting Guide14.1 Refrigeration Cycle SystemIn order to diagnose malfunctions, ensure the air conditioner is freefrom electrical problems before inspecting the refrigeration cycle.Such problems include insufficient insulation, problem with thepower source, malfunction of a compressor and a fan. The normaloutlet air temperature and pressure of the refrigeration cycledepends on various conditions, the standard values for them areshown in the table to the right.Normal Pressure and Outlet Air Temperature (Standard)Gas Pressure Outlet airMpaTemperature(kg/cm 2 G)(°C)Cooling Mode 0.9 ~ 1.2 (9 ~ 12) 12 ~ 16Condition: Indoor fan speed = HighOutdoor temperature = 35°C at cooling mode.Compressor operate at rated frequencyDifferent in the intakeand outletair temperaturesMore than 8°C(15 minutes after anoperation is started) atcooling mode.Normal• Measuring the airtemperature differentLess than 8°C at the cooling modeValue of electric currentduring operationHigher than specifiedDusty condenserpreventing heat radiation• Measuring electric currentduring operationExcessive amountof refrigerantLower than specifiedGas sidepressureCoolingModeHighInefficient compressor• Measuring gas sidepressureLowInsufficient refrigerantLowClogged strainer orcapillary cube56
