15.5.24 F95 (Cooling High Pressure Abnormality) Malfunction Decision Conditions � During operation of cooling, when outdoor unit heat exchanger high temperature data (61°C) is detected by the outdoor pipe temperature sensor. Malfunction Caused � Air short circuit at indoor unit � Dust accumulation on the indoor unit heat exchanger � 2/3 way valve closed � Faulty outdoor unit fan motor � Excessive refrigerant � Clogged expansion valve or strainer � Faulty outdoor pipe temperature sensor � Faulty outdoor unit PCB Troubleshooting 84
15.5.25 F96 (IPM Overheating) Malfunction Decision Conditions � During operating of cooling and heating, when IPM temperature data (100°C) is detected by the IPM temperature sensor. Multi models only o Compressor Overheating: During operation of cooling and heating, when the compressor OL is activated. o Heat Sink Overheating: During operation of cooling and heating, when heat sink temperature data (90°C) is detected by the heat sink temperature sensor. Malfunction Caused � IPM overheats due to short circuit of hot discharge air flow. � IPM overheats due to defective of outdoor fan motor. � IPM overheats due to defective of internal circuitry of IPM. � IPM overheats due to defective IPM temperature sensor. Multi Models Only o Compressor OL connector poor contact. o Compressor OL faulty. Troubleshooting 85
