1. Cause of malfunction
1) Problematic EEPROM version
2) Problematic EEPROM IC
3) Faulty outdoor unit PBA
2. Check procedure
1) Replace EEPROM IC
2) Replace outdoor unit PBA (a new EEPROM ic must be inserted)
Equipment claims must be made at a service center for the EEPROM IC.
Fault receipts regarding outdoor units such as EEPROM
After verifying model and code of customer product,
make equipment claim at the service center
(Will be loaded according to each code and released
as service material)
The servicing professional will insert the
EEPROM IC on location (If an ic has already been inserted,
a replacement will suffice)
If the same problem still occurs, the PBA will be replaced
(In this case the claimed EEPROM IC must be inserted)
▶
Because the identical PBA is commonly used in several models,
EEPROM data is not loaded onto new PBAs. Therefore, when
replacing
old PBAs with new ones, the claimed EEPROM ic must be used.

Release after downloading EEPROM from the
first in-house line (EEPROM ic is absent in this case due to it
being loaded on main micom)
