Troubleshooting Guide Troubleshooting Guide Piping System CONDENSER COIL FAN CAPILLARY TUBE MOTOR COMPRESSOR BLOWER EVAPORATOR COIL Figure 38 is a brief description of the important components and their function in what is called the refrigeration system. This will help you to understand the refrigeration cycle and the flow of the refrigerant in the cooling cycle.
Troubleshooting Guide Troubleshooting Guide In general, possible trouble is classified in two kinds. The one is called Starting Failure which is caused from an electrical defect, and the other is ineffective Air Conditioning caused by a defect in the refrigeration circuit and improper application. Unit runs but poor cooling. Ineffective Cooling Check cold air circulation for smooth flow. Check outdoor coil (heat exchanger) and fan operation. Dirty indoor coil (heat exchanger) Check gas leakage.
Troubleshooting Guide Fails to Start Check of power source. Check of circuit breaker and fuse. Check of control panel setting. Check control panel. Compressor fails only to start. Fan only fails to start. Drop of power voltage. Defect of compressor capacitor. Capacitor check. Improper thermistor setting Loose terminal connection Improper wiring Improper wiring. Defect of fan motor capacitor. Irregular motor resistance (Ω) Irregular motor insulation (Ω) Replacement. Replacement of fan motor.
Troubleshooting Guide ELECTRIC PARTS TROUBLESHOOTING GUIDE: Possible Trouble 1 Is the Trans input power AC 115V? • The unit does not operate. NO • Check the Fuse. • Check the wiring diagram. YES Is the Trans output power about AC 14V? NO YES Is output Voltage of IC01D DC 12V? Is shorted the Trans. output? YES NO NO • Check the Main P.W.B pattern. • Exchange the Trans. • Exchange D02D~D05D. • Exchange IC01D. YES Is output Voltage of IC02D DC 5V? NO • Exchange IC02D.
Troubleshooting Guide Possible Trouble 2 • The compressor does not operate. Is Temp. NO setting set lower than Room Temp.-0.5°C? • Set the Temp. setting to lower Temp. YES Is the voltage No.10 of IC01M 0V? NO Is the voltage N0.7 of IC01M DC 5V? NO YES YES • Check the RY-COMP. • Check the wiring Diagram. • Exchange IC01M. Is the Unit for 3 minutes delay? NO YES • Wait 3 Minutes • Exchange MAIN P.W.B Ass'y.
Troubleshooting Guide • Romote controller does not operate. Possible Trouble 5 Is the voltage of Battery about over 2.3V? NO • Exchange the battery. YES Is the voltage No.16 of CN-DISP1 on Main P.W.B Ass'y DC 5V? NO • Check the P.W.B pattern. YES NO Is the connection of CN-DISP1 all right? • Connect connector to CN-DISP1 exactly. YES • Exchange Receiver Ass'y. Possible Trouble 6 Is the IC01G all right? • It displays abnormally on Display P.W.B Ass'y. NO • Exchange IC01G.
Troubleshooting Guide ROOM AIR CONDITIONER VOLTAGE LIMITS NAME PLATE RATING MINIMUM MAXIMUM 115V ± 10% 103.5V 126.5V COMPLAINT Fan motor will not run. CAUSE REMEDY No power Check voltage at outlet. Correct if none. Power supply cord Check voltage to rotary switch. If none, check power supply cord. Replace cord if circuit is open. Rotary switch Check switch continuity. Refer to wiring diagram for terminal identification. Replace switch if defective.
Troubleshooting Guide COMPLAINT Fan motor noise. Compressor will not run, fan motor runs. CAUSE REMEDY Fan If cracked, out of balance, or partially missing, replace it. Blower If cracked, out of balance, or partially missing, replace it. Loose set screw Tighten it. Worn bearings If knocking sounds continue when running or loose, replace the motor. If the motor hums or noise appears to be internal while running, replace motor. Voltage Check voltage. See the limits on the preceding page.
Troubleshooting Guide COMPLAINT Compressor cycles on overload. Compressor cycles on overload. Insufficient cooling Excessive noise 27 Room Air Conditioner CAUSE REMEDY Voltage Check the voltage. See the limits on the preceding page. If voltage is not within these limits, call an electrician. Overload Check overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.) Fan motor If not running, determine the cause.
