Samsung Mini Split C467 Error Code

What C467 means

C467 is generation-dependent on Samsung RAC mini splits. Official Samsung service documentation maps C467 to Compressor wire missing / rotation error - the inverter cannot detect compressor rotation, typically a compressor wiring connection fault; SplitAtlas, presenting the current R-32 residential mapping, reads C467 as a prohibit-operation condition in HEATING when outdoor conditions are outside the allowed range. The wiring reading is an electrical fault; the prohibit reading is normally protective and self-clearing.

First checks before service

This page currently documents the safe reset triage. If the code returns, use the linked source manual or a qualified technician for code-specific diagnosis.

1. 1. One-time fault event (power disturbance or transient sensor reading) common DIY

   Check: Power-cycle at the breaker/disconnect (or unplug for CPAP), restore, and run the system while watching for the code.

   Fix: If the code does not return after a full run cycle, the fault was transient — monitor, no repair needed.

2. 2. Fault persists after a clean reset occasional pro only

   Check: If the code returns immediately or every session, note the conditions (startup, heating, after rain).

   Fix: A persisting code points at the component the manual assigns to this code — that repair is technician territory.
