trobleshoting ac inventer

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
