NO YES Check the same items as [P22] error. Is there no element which interfere heat exchange of outdoor unit? • Clogging of heat exchanger • Short circuit YES NO Eliminate interfering element. Check overcharge of refrigerant, clogging of cycle, broken pipe, abnormal overload, etc. Defect → Correct defective position. Does indoor fan normally operate? NO Are indoor fan motor and connector normal? NO YES YES Repair defective position. Are resistance values of indoor TC and TCJ sensors normal? NO Replace sensor. Is there no element which interfere heat exchange of indoor unit? • Clogging of filter • Clogging of heat exchanger • Short circuit NO YES YES Check indoor P.C. board. Defect → Replace Eliminate interfering element. Check overcharge of refrigerant, clogging of cycle, broken pipe, abnormal overload, etc. Defect → Correct defective position. – 117 –
