What E563 means on a Samsung air conditioner

Error code E563 on a Samsung air conditioner indicates a software version mismatch between the indoor unit's MICOM (Microcomputer) control module and the system's current firmware requirements. Specifically, this error is triggered when a replacement or newly installed module in the indoor unit contains an outdated software version that is incompatible with the rest of the system. The MICOM is the central control board that manages communication between components, processes sensor inputs, and coordinates operation of the indoor unit. When its firmware is too old to communicate correctly with other system components, the unit logs E563 and typically halts normal operation.

The most direct cause is the installation of a control module that was manufactured or stored with an older firmware version. This commonly occurs after a control board replacement where the replacement part was not pre-flashed with current software. It can also appear after system upgrades where the main unit firmware was updated but the indoor unit module was not brought up to the same version level. Samsung's MICOM-based systems require version parity across communicating components to function correctly.

The primary diagnostic step is to check the MICOM version currently loaded on the indoor unit's control module and compare it against the required version for the system. If the version is outdated, a software upgrade must be performed using the appropriate Samsung service tool or firmware update procedure. In some cases, the replacement module must be sourced with the correct pre-loaded firmware version.

Common causes of E563

  1. 01

    Replacement module installed with outdated firmware

    Wiring / connection

    A control board replaced during a prior repair may have been sourced with an older software version. This is the most common trigger for E563 and is identified by checking the MICOM version on the newly installed board.

  2. 02

    System firmware updated without updating the indoor unit module

    Wiring / connection

    If other system components received a firmware update but the indoor unit MICOM was not updated at the same time, a version mismatch results. Reviewing firmware versions across all communicating units will confirm this.

  3. 03

    Long-stored replacement part with legacy firmware

    Wiring / connection

    Replacement modules that sat in inventory for an extended period may carry firmware versions that predate current system requirements. This is identified by comparing the part's firmware version against current specifications at the time of installation.

  4. 04

    Incorrect module installed for the system configuration

    Part replacement

    Installing a MICOM module intended for an older system variant can produce this error if that module's software version is not compatible with the current indoor unit platform. Verifying the part compatibility against the specific model is necessary.

Frequently asked questions about E563

What does E563 mean on a Samsung air conditioner?
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.
How do I fix error code E563 on my Samsung air conditioner?
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.
Will resetting my Samsung air conditioner clear error E563?
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.
Is it safe to run my Samsung air conditioner while E563 is displayed?
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.
How much does it cost to fix error E563 on a Samsung air conditioner?
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.
