16.4.27 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 ∞ 74
17. Disassembly and Assembly Instructions WARNING High Voltage is generated in the electrical parts area by the capacitor. Ensure that the capacitor has discharged sufficiently before proceeding with repair work. Failure to heed this caution may result in electric shocks. 17.1 <strong>Indoor</strong> Electronic Controllers, Cross Flow Fan and <strong>Indoor</strong> Fan Motor Removal Procedures 17.1.1 To remove front grille 17.1.1.1 To remove power electronic controller 75
