Details of Alarm MessagesAlarm Details(1-1) [Alarm “P29”] Start-up failure of the compressor (will not start up)Related parts• HIC PCB (Model: [U-200PE1E8, U-250PE1E8] HIC-C906VH8)• Outdoor unit control PCB (Model: [U-200PE1E8, U-250PE1E8] CR-C906VH8P)• Filter PCB (Model: [U-200PE1E8, U-250PE1E8] FIL-C906VH8)Start of defect diagnosisIs the power voltage correct? Improve the power voltage line.Check the following:Check to ascertain that the power voltage is within the permissible range of 198 to 264Vfor indoor unit or 342 to 456V for outdoor unit regardless of whether the compressor isoperating or not.* Pay special attention to whether the voltage drops after compressor operations whilemeasuring.Repair the wiring connectors.Replace the outdoorunit control PCB.Are the wiring connectorconnections OK?Are the U/V/Wconnections on the HICPCB and compressorterminal OK?Are the capacity settingfor the outdoor unit ofthe outdoor unitAre the resistancevalues permissible at allareas in HIC PCB?Is the insulation on thecompression OK?Has the HIC PCB beenreplaced?Has the outdoor unitcontrol PCB beenreplaced?Replace the compressorHas the filter PCBbeen replaced?Repair the wiring connectors.Repair the HIC PCB.Repair the compressor.Repair the HIC PCB.Replace the filter PCB.Correct the capacity setting for the outdoor unit.HIC PCB sideU (CN202) pinkV (CN203) whiteW (CN204) blueAs the compressors used with the U-200PE1E8 and U-250PE1E8are different, there is a possibility that a P29 error will be triggeredif the unit's capacity settings are incorrect.No (Abnormal resistance value)(No problem with the resistance value)• Inspection Method: Remove the HIC PCB and measure the resistance at all areas.See attached documentation.Replace the HIC PCB if the readings are below permissible values.(No problem with the insulation)No (Defective insulation)• Potential cause: PCB Insulation failure caused by thecompressor lock.• Verifi cation MethodRemove the wires from the connectors on the top of thecompressor. Measure the insulation resistance of the U, V andW phases and confirm that they are 1M or more.Potential problems are most likely in accordance with thefollowing sequence when it is determined that the PCB istrouble with an alarm P29.1.
