System failure
40~104 indicates communication failure between IDU and ODU, for example, 40 indicates
communication failure between IDU 1# and ODU, 41 indicates communication failure
between IDU 2# and ODU, and so on.
2. Common fault handling and analysis
2.1 Compressor drive overheat
Code displayed:
ODU main board displays E006/E030 (applicable to AA/AS/AX models).
Fault detection method:
use a thermistor to measure the temperature of fins on inverter
drive board for compressor.
Fault identification conditions:
when the thermistor detects a temperature beyond set
range.
P Thermistor on circuit board
Possible causes:
①
thermal conductive silicon grease is applied unevenly
②
Cold plate is not tightened by fixing screws
③
Inverter drive board fault
④
Too high outdoor temperature results in poor heat exchanging
⑤
Outdoor fan is not working or working at an abnormal speed
