5-555-3. Symptoms and Parts to InspectRemotecontrolleralarm displayAlarmcontents Judgement conditions Eliminatingcondition of alarm Judgement and correctionP03 Abnormal dischargetemperature error.•Discharge temp.detected at or abovethe specified value.Stops when temp. exceeds115 .Alarm output on 4 pre-trips.Recovery at restart 1. Check refrigerant cycle (gasleak).2.Trouble with electronicexpansion valve.3.Check dischargetemperature sensor (TD).P05 Missing phasedetected.(CT disconnectedor AC power supplyerror)The current value transmittedfrom the microcomputer on theoutdoor unit control substrate islow.When no AC power input formore than 3 minutes: Pre-trip 5times.Recovery at restart 1.Check R/S/T power supply.2.Check HIC circuit.3.Check outdoor unit controlPCB.P15 Insufficient gas leveldetected.•Discharge temperature is 100or higher.•Electronic expansion valve is atStep 960.•The current value from the MDCis 6.0A (three-phase) / 3.5A(single-phase) or less.When the above has continuedfor 1 minute.Recovery at restart 1.Check refrigerant cycle (gasleak).2.Trouble with electronicexpansion valve.3.Check outdoor unit valveopening.P19 4-way valve lockedtrouble.•Judged after5 minutes hadelapsed since thecompressor wasswitched on.The indoor unit heat exchangertemperature drops eventhough the compressor isswitched on during the heatingmode.[min(E1,E2)] is 10or lower.The indoor unit heatexchanger temperature riseseven though the compressor isswitched on during the coolingmode.E2 is 50 or higher Pre-trip 2 timesRecovery at restart 1. Check 4-way valve.2. Check 4-way valve wiring.3. Check outdoor unit controlPCB.P20 High-pressureprotection errorcaused by coolinghigh-load max (C1,C2) temperature.Halted if the temperatureexceeds 64 .Error output on 4 consecutivepre-trips.Recovery at restart 1.Overload operation ofrefrigerant cycle.2.Check outdoor unit heatexchanger temperaturesensor C1 and C2.P22 Outdoor unit fanmotor trouble.•Inverter protectioncircuit wasactivated, or lockwas detected atoutdoor unit fanmotor.Inverter stops after alarm isdetected. Pre-trip 4 timesRecovery at restart 1.Position detection trouble.2.Outdoor unit fan motor over-current Protection circuit isactivated.•Check outdoor unit controlPCB.•Refer to outdoor unit fanjudgement methods.P26 Inverter protectorcircuit was activated.G-Tr short-circuitwithin the HICcircuit.(Short time /0.8 seconds or less)HIC temperatureprotectionInverter stops after alarmis detected. Alarm is outputwhen inverter stops (pre-trip)consecutively 4 times.Recovery at restartTemperature dropped1.Stops immediately evenwhen operations restarted.•Layer short on thecompressor2.Check HIC circuit.•Wiring trouble3.Heat sink and PCB (HIC)•Contact trouble
