14.4.21 F99 (Output Over Current Detection)Malfunction Decision ConditionsDuring operation of cooling and heating, when an output over-current (18.5A) is detected by checking the current thatflows 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 usingthe 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 (-) UVWTester’s positive terminal UVW Power transistor (+) UVW Power transistor (-)Normal resistanceSeveral kΩ to several MΩAbnormal resistance0 or ∞80
15. Disassembly and Assembly InstructionsWARNINGHigh Voltage is generated in the electrical parts area by the capacitor. Ensure that the capacitor has discharged sufficiently before proceeding withrepair work.
