Samsung Air Conditioner Error Code E563

E563 indicates that the indoor unit's MICOM control module has an outdated software version that is incompatible with the system. This is a firmware version mismatch error, most often appearing after a control board has been replaced. The system flags this to prevent communication errors or unsafe operation caused by software incompatibility.

A simple power reset will not clear E563 because the error is caused by an underlying software version mismatch, not a temporary fault. The error will return immediately after restart until the MICOM firmware is properly updated. A reset is not a substitute for the required software upgrade.

If the issue is resolved through a firmware update alone, costs are primarily for the technician's diagnostic and labor time, which can range from roughly 75 to 150 dollars depending on the service provider and region. If the installed control module cannot be updated and must be replaced with a correctly versioned unit, total costs including parts and labor can range from 150 to 400 dollars or more depending on the specific model.

The fix requires checking the current MICOM firmware version on the indoor unit's control module and performing a software upgrade to bring it up to the required version. This procedure is typically done by a qualified technician using Samsung's service tools. In some cases, if the installed module cannot be updated, a correctly versioned replacement module may be needed.

When E563 is active, the unit is typically unable to operate normally due to the communication issues caused by the firmware mismatch. Attempting to force operation is not advisable, as the MICOM module controls critical functions including safety monitoring. The error should be resolved before the unit is put back into regular use.
