2.21 Kenaikan Suhu Sirip Radiasi Inverter
Kode Kesalahan
L4
Model yang
berlaku
RQQ8-48PY1
Metode Deteksi
Kesalahan
Radiasi PCB inverter kompresor
Suhu sirip radiasi terdeteksi oleh termistor sirip radiasi.
Kondisi
Keputusan
Kesalahan
Ketika suhu sirip radiasi inverter meningkat 87°C.
Dugaan
sebab
Aktuasi termal sirip (Aktuasi di atas 87°C)
PCB inverter rusak
Termistor sirip radiasi rusak
Penyelesaian
Masalah
Perhatian
Be sure to turn off the power switch before connecting or disconnecting
connectors, or parts may be damaged.
Defective radiation from the power
unit
• Blocked air suction port
• Stained radiation sirip
• High outdoor air temperature
Replace the termistor.
Replace the PCB Inverter (A4P).
Continue the operation.
It is supposed that the radiation
sirip temperature became high
due to some field factors. In this
connection, check the following
points:
• Stained radiation sirip
• Airflow obstructed with dirt or
foreign matters
• Damage to fan impellers
• Too high outdoor air
temperature
Connect and disconnect the
connector (X111A) for the
radiation fin thermistor, and
then properly connect it.
Is the thermistor
resistance normal?
NO
YES
Does the
error recur when the
power supply turns
ON to start the
compressor?
YES
NO
The radiation fin of the inverter
YES
PCB concerned exceeded a
temperature of 87°C.
NO
Turn OFF the power supply,
and then make measurement
of resistance of the radiation
fin thermistor.
