CARA MENDETEKSI KERUSAKAN PADA AC PANASONIC INVERTER 1.Arahkan remote ac ke indoor ac 2.tekan tombol on/off untuk menghidupkan ac 3.Aktifkan tombol interrogate dengan menekan tombol timer up/ chek selama 5 detik 4.display akan muncul huruf H sbga tanda bahwa mode interrogate sudah aktif 5.selanjutnya tekan tombol timer up/down,jika terdengar bunyi buzzer/ bip sekali itu artinya normal,namun jika terdengar bunyi 4x berturut turut itu pertanda ada trouble.dan lihat di display remote akan muncul kode kerusakan. kode-kode trouble pada ac inverter panasonic H 11 =Comunication failure (faulty wiring or other problem with Id/OD comunication) H 12 =ID/OD compatibility problem (over or under indexed multi system) H 14 =indoor air sensor faulty (sensor disconect,faulty or contacts dirty) H15 =Compressor sensor faulty (sensor disconect,faulty or contacts dirty) H16 =current transformer problem (power transisitor module or outdoor pcb faulty,or low gas) H19 = indoor fan motor locked (fan motor of indoor pcb failure) H21 = float switch operated (chek drainage) H23 = indoor pipe sensor faulty (sensor disconect,faulty or contacts dirty) H27 = outdoor air sensor faulty (sensor disconect,faulty or contacts dirty) H28 = outdoor pipe sensor faulty ( sensor disconect,faulty or contacts dirty) H30 =outdoor discharge sensor 1 faulty ( sensor disconect,faulty or contacts dirty) H32 = outdoor discharge sensor 2 faulty ( sensor disconect,faulty or contacts dirty) H 33 =incorrec conection voltage (indoor or outdoor incorrec or faulty wiring) H34 = outdoor heatsink sensor faulty ( sensor disconect,faulty or contacts dirty) H36 = outdor gas sensor faulty ( sensor disconect,faulty or contacts dirty) H37 = outdoor liquid sensor faulty (sensor disconect ,faulty or contacts dirty) H39 = indoor abnormal operation (incorrect piping or exspansion valve problrm) H41 =abnormal wiring or piping (wiring or piping crossed on a twin system) H97 =outdoor fan failure (outdoor fan motor or pcb failure) H98 = indoor coil overheat [heat mode] (dirty filters indoor coil. very hight room temperature) H99 = indoor coil de-ice [cool mode] (dirty filters indoor coil.low gas charge or low ambient temperature) F11 =reversing valve failure (faulty reversing valve,coil or outdoor pcb) F17 =stanbay units frezzing (multi only.exspansion valve leakage) F90 =pfc failure (problem with inverter or compressore) F91 =refrigerans cycle problem ( low gas or blockage) F93 = compressor abnormal revolution ( compressore runing incorectly) F95 = outdoor coil over heat [cool mode] ( dirty condensor coil, low gas or blockage) F96 =ipm or compressore overheating (excess or low gas charge or dirty heat exchangers) F97 =high discharge / compressor temperature ( low gas charge or failled compressor) F98 =over current protection (outdoor heat exchanger problem.excess gas) F99 =DC overcurrent protection (outdoor pcb,power transistor or compressor failure) jika sudah ketemu kerusakannya segera perbaiki atau ganti sparepart yang rusak.. SEMOGA BERMANFAAT..
