Samsung Mini Split C462 Error Code
Check your model first
- SplitAtlas (current R-32 residential mapping per SplitAtlas)
- CONFLICT NOTE
Match the model on your equipment label to the linked manufacturer documentation. The same code can mean different things across model families.
Quick answer
Samsung C462 maps to AC Input I_limit trip error in official Samsung service documentation (older Avant RAC series); SplitAtlas reads it as GAS LEAK on current R-32 systems. Samsung C-code meanings are generation-dependent - check your model's manual. Sealed-system work is technician-only.
Severity: high · DIY difficulty: easy
Safety
Stop at the breaker power-cycle and any plug-accessible checks (filters, remote settings, visible wiring). The outdoor unit's capacitor holds a lethal charge and the refrigerant circuit is both pressurized and (on R-32 units) flammable — opening panels or servicing the sealed system is licensed-technician work (EPA 608).
What C462 means
C462 is generation-dependent on Samsung RAC mini splits. Official Samsung service documentation (Avant RAC service manual; WindFree 3.0 AR+C installer quick guide DB68-12003A-01) maps C462 to AC Input I_limit trip error - the inverter tripped on input-current limit. SplitAtlas, presenting the current R-32 residential mapping, reads C462 as GAS LEAK error on an R-32 system (A2L mildly flammable refrigerant). Both readings are protection faults requiring service; the gas-leak reading is refrigerant-related and strictly technician work.
Code meaning varies by series
- SplitAtlas (current R-32 residential mapping per SplitAtlas): GAS LEAK error on an R-32 system (SplitAtlas)
- CONFLICT NOTE: SplitAtlas presents C462 as a GAS LEAK error; two official Samsung documents (Avant RAC service manual and WindFree 3.0 installer quick guide DB68-12003A-01) both map C462 to AC Input I_limit trip error, and map gas leak to C554. Samsung's code assignments differ between product generations - verify against the specific model's manual.
First checks before service
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. 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.
