Indoor Unit Controller PCB
Error 11 indicates a 'Model Information Error' where the indoor unit's microcomputer cannot verify the unit's capacity or configuration settings. This is usually caused by a failure of the EEPROM or a logic mismatch on the Printed Circuit Board. Replacing the controller PCB restores the factory-calibrated model data required for the indoor and outdoor units to communicate and operate the inverter compressor correctly.
