1. Current sensor error: Upload EEPROM to the main PBA of the outdoor unit.
After checking for normal operation of PCB, replace the inverter PCB.
2. Compressor Vlimit error: E465
If the compressor is abnormally run, replace the compressor and then ensure that it works normally.
ĺ If the compressor is normally run, check the assembling between the heatproof plate and the inverter PBA and then if there is no abnormality,
replace the inverter PBA.
3. OTP error: E471
Upload EEPROM to the main
PBA of the outdoor unit.
4. Capacity inconsistence error: E556
Check the model name between the outdoor and indoor unit and re-enter the option code to the indoor unit.
5
. 3-phase power cable disconnection: E424
Check for disconnection of the 3-phase (open) power cable, and check the disconnected EMI PBA fuse.
6. Outdoor unit freezing detection (at the stop of the compressor): E403
Outdoor overload protection control (at the stop of the compressor): E404
- Check whether the fan and the motor o
perate normally.
- Check the operation of EEV.
- Check the temperature sensor of the indoor unit heat exchanger.
- Check the indoor unit inlet blocking.
7. Outdoor unit compress
or discharging temperature protection control: E416
- Check for lack of refrigerant.
- Check the blocking of the solenoid valve.
- Check the malfunction of the exhaust tempera
ture sensor.
- Check EEV.
8. Error of impossibility to operate heating at outdoor temperature exceeding 30°C: E440
Error of impossibility to operate cooling at ou
tdoor temperature of -5°C or under: E441
- It is not the error code in the product and it is a specification to protect the product by limiting the temperature scope of u
se.
- Use by referring to the temperature scope of use on the product manual, etc.
9. OLP overheating and compressor stop: E463
- Check the opening of the sub-valve.
- Chec
k the amount of the cooling water.
- Check OLP sensor.
10. Current sensor error: E468
- Check EEPROM data.
- Check PCB operation.
11. IPM (IGBT Module) or PFCM temperature senso
r error: E474
IPM overheat error for outdoor unit inverter compressor: E500
- Check whether IPM is correctly assembled on the heatproof plate.
- Check whether the inlet is bloc
ked.
- If there is a defect, replace IPM.
