What E560 means on a Samsung air conditioner

The E560 error code on a Samsung air conditioner indicates an outdoor unit option switch setting error, specifically that an inappropriate or conflicting option switch is active. Option switches on outdoor units are physical DIP switches or configurable settings that define operational parameters for the unit, such as capacity matching, refrigerant type, communication mode, or regional configuration. When the control board detects a switch combination that does not correspond to a valid or supported configuration, it triggers E560 to prevent the unit from operating under potentially damaging or incompatible conditions.

This error most commonly surfaces after installation, maintenance work, or a control board replacement where the option switches were not properly verified or were accidentally changed. Each switch position contributes to a binary configuration code that the main control board reads during startup and periodically during operation. If even one switch is in an incorrect position relative to the unit's model requirements or system setup, the board will flag the entire configuration as invalid.

Resolving E560 requires physically inspecting the option switch array on the outdoor unit control board, cross-referencing each switch position against the configuration requirements for that specific model, and correcting any switches that are set incorrectly. Simply resetting the unit will not clear this error if the switch positions remain improper. Technicians should ensure the unit is powered down before adjusting DIP switches to avoid board damage or misreading of transitional states.

Common causes of E560

  1. 01

    Incorrect DIP switch configuration after installation

    Wiring / connection

    During initial installation, the option switches on the outdoor control board may have been set incorrectly or left in a default position incompatible with the specific unit or system configuration. Technicians should verify each switch position against the model-specific requirements.

  2. 02

    Accidental switch change during servicing

    Wiring / connection

    Maintenance or repair work performed near the control board can inadvertently shift one or more DIP switches. Inspect all switch positions carefully after any recent service visit to the outdoor unit.

  3. 03

    Control board replacement without reconfiguring switches

    Wiring / connection

    When a new outdoor unit control board is installed, the option switches on the replacement board may not match the original configuration. All switch positions must be manually set to match the previous or required configuration before startup.

  4. 04

    Failed or damaged DIP switch

    Part replacement

    A physically damaged or stuck DIP switch may prevent a correct setting from being established, causing the board to read an invalid configuration even when the correct position is attempted. Visual inspection and continuity testing can help identify a faulty switch.

  5. 05

    Outdoor unit control board fault

    Part replacement

    In some cases, the control board itself may be misreading the switch positions due to an internal fault, component failure, or moisture damage on the board. If switch positions are confirmed correct but E560 persists, board replacement may be necessary.

Frequently asked questions about E560

What does E560 mean on a Samsung air conditioner?
E560 indicates an outdoor unit option switch setting error, meaning one or more configuration switches on the outdoor unit control board are set to an inappropriate or unsupported position. The control board reads these switches to determine operational parameters, and an invalid combination causes it to halt operation and display this code. A technician needs to inspect and correct the switch settings to resolve the error.
Can I fix E560 myself, or do I need a technician?
Correcting this error involves accessing the outdoor unit control board and adjusting DIP switches to the proper configuration for your specific model. While the task itself is not electrically complex, identifying the correct switch positions requires model-specific configuration data and comfort working inside the outdoor unit. Most homeowners should have a qualified HVAC technician handle this to avoid setting switches incorrectly and causing additional faults.
Will resetting the air conditioner clear the E560 error?
No, a simple power reset will not clear E560 if the option switches remain in incorrect positions. The control board re-reads the switch configuration each time it powers up, so the error will return immediately after restart. The physical switch settings must be corrected first before the error will clear.
Is it safe to keep running the air conditioner while E560 is displayed?
The unit will typically not operate normally while E560 is active, as the error indicates the system does not have a valid configuration to run under. Attempting to force operation in this state is not advisable, as running with an unsupported option switch configuration could potentially cause incorrect behavior or damage to components. The error should be resolved before resuming normal use.
How much does it cost to repair a Samsung air conditioner E560 error?
If the fix is simply correcting the DIP switch positions, the cost is primarily a service call fee, which typically ranges from $75 to $150 depending on your location and the technician. If the error is caused by a damaged DIP switch assembly or a faulty outdoor control board, parts and labor costs can range from $150 to $500 or more. Getting a diagnostic visit to confirm the exact cause will give you a more accurate estimate.
