Full Diagnosis
Indoor Unit EEPROM Parameter Error. Indoor unit main chip does not receive feedback from the EEPROM chip; installation or PCB fault suspected.
All Recorded Causes
Power cycle the indoor unit. If error persists, the indoor control board EEPROM has corrupted data and the control board must be replaced.
Verify Before Replacing Parts

- Confirm filter condition, blower operation, and coil cleanliness before replacing any controls — start by ruling out whether power cycle the indoor unit.
- Measure airflow-related readings that match the symptom, such as temperature split or static pressure, and check whether if error persists, the indoor control board EEPROM has corrupted data and the control boar….
- After the correction, run the system long enough to confirm the ductless systems fault does not return under normal load.
