Cause
• Broken heat exchanger sensor wire, poor connector connection
• Broken room temperature sensor wire, poor connector connection
• Defective power supply
• Defective fan motor, poor connector connection
Cause
• Broken outdoor sensor wire, poor connector connection
• Broken heat exchanger fluid pipe sensor wire, poor connector connection
• Broken discharge pipe sensor wire, poor connector connection.
• Defective compressor
• Open phase on compressor
• Defective outdoor unit boards
Cause
• Compressor locking, open phase on compressor output, shortcircuit on power
transistor, closed service valve
• Broken power transistor, broken compressor wire
• Broken discharge pipe sensor wire, poor connector connection
• Compressor blockage
• Overload operation, overcharge
• Broken power transistor
• Gas shortage, defective discharge pipe sensor, closed service valve
• Defective power supply, Broken signal wire, defective in/outdoor unit boards
• Defective fan motor, poor connector connection
• Gas over charge, short circuit of outdoor unit
Sebab
• Wayar sensor penukar haba terputus, sambungan penyambung kurang baik
• Wayar sensor suhu bilik terputus, sambungan penyambung kurang baik
• Bekalan kuasa lemah
• Motor kipas rosak, sambungan penyambung kurang baik
Sebab
• Wayar sensor luar terputus, sambungan penyambung kurang baik
• Wayar sensor paip bendalir penukar haba terputus, sambungan penyambung
kurang baik
• Wayar sensor paip luahan terputus, sambungan penyambung kurang baik.
•
Pemampat rosak
• Pemampat dalam fasa terbuka
• Papan unit luar rosak
Sebab
• Pemampat terkunci, output pemampat dalam fasa terbuka, litar terpintas pada
transistor kuasa, injap perkhidmatan tertutup
• Transistor kuasa rosak, wayar pemampat terputus
• Wayar sensor paip luahan terputus, sambungan penyambung kurang baik
• Pemampat tersumbat
• Operasi beban lebih, cas berlebihan
• Transistor kuasa rosak
• Kekurangan gas, sensor paip luahan rosak, injap perkhidmatan tertutup
• Bekalan kuasa lemah, Wayar isyarat terputus, papan unit dalam rumah/luar rosak
• Motor kipas rosak, sambungan penyambung kurang baik
• Kelebihan isi gas, hubung-singkat unit outdoor
