Samsung Mini Split C461 Error Code

Updated 2026-08-29 · review status: manual-verified Last verified: 2026-08-29

Quick answer

C461 means an EEPROM data error (no data) on the outdoor unit - the outdoor board cannot read its stored option/setting data, so the system will not run reliably. A brief power event or brownout is the most common trigger; a failed EEPROM, loose harness, or outdoor PBA fault explains codes that return.

Severity: high · DIY difficulty: intermediate

Safety

Only a power-cycle reset and visual checks you can do without removing any panel. Do not open the indoor or outdoor unit, test board voltages, touch capacitors (they hold lethal charge), re-pin wiring, or replace PCBs.

What C461 means

C461 means an EEPROM data error (no data) on the outdoor unit - the outdoor board cannot read its stored option/setting data, so the system will not run reliably. A brief power event or brownout is the most common trigger; a failed EEPROM, loose harness, or outdoor PBA fault explains codes that return.

Code meaning varies by series

  • Samsung AR09TXFYAWKNEU service manual, outdoor display table (p3-2-2): C461 EEPROM data error (no data)
  • Same manual, outdoor fan/compressor section (p3-2-10): C461 also appears as compressor starting error - the manual shows C461 under both headings; compressor-start diagnosis is listed separately under C464/C467. Confirm the exact code and symptoms before parts replacement.

Causes, ranked

  1. 1. Brief power event, brownout, or unstable supply corrupted the control-memory read occasional diy-ok

    Check: Turn the system off with the remote, then power cycle once at the breaker or disconnect (leave off 3 minutes). A temporary memory fault usually clears.

    Fix: One reset only. If C461 returns, stop resetting and schedule service - repeated resets do not fix a stored-data fault.

  2. 2. Loose EEPROM connector, harness, or outdoor electrical connection occasional pro-only

    Check: Technician only: inspect connectors and harness seating on the outdoor PBA.

    Fix: Technician: reseat/repair harness, verify power supplies to the board.

  3. 3. Failed EEPROM chip or outdoor main/inverter PBA occasional pro-only

    Check: Technician only: verify board part number and option/setup data; EEPROM communication and PBA status checks.

    Fix: Technician: option re-setup (remote option mode or S-Net Pro2) or EEPROM/PBA replacement.
