15.4.29 F98 (Input Over Current Detection) Malfunction Decision Conditions • During operation of cooling and heating, when an input over-current (16.8A) is detected by checking the input current value being detected by current transformer (CT) with the compressor running. Malfunction Caused • Over-current due to compressor failure. • Over-current due to defective outdoor unit PCB. • Over-current due to defective inverter main circuit electrolytic capacitor. • Over-current due to excessive refrigerant. Troubleshooting 88
15.4.30 F99 (Output Over Current Detection) Malfunction Decision Conditions • During operation of cooling and heating, when an output over-current (18.5A) is detected by checking the current that flows in the inverter DC peak sensing circuitry. Malfunction Caused • DC peak due to compressor failure. • DC peak due to defective power transistor(s). • DC peak due to defective outdoor unit PCB. Troubleshooting • Checking the power transistor • Never touch any live parts for at least 10 minutes after turning off the circuit breaker. • If unavoidable necessary to touch a live part, make sure the power transistor’s supply voltage is below 50V using the tester. • For the UVW, make measurement at the Faston terminal on the board of the relay connector. Tester’s negative terminal Power transistor (+) UVW Power transistor (-) UVW Tester’s positive terminal UVW Power transistor (+) UVW Power transistor (-) Normal resistance Several kΩ to several MΩ Abnormal resistance 0 or ∞ 89
