Check your model first

  • Samsung C-series ductless (WindFree Premium R-32 and related)
  • Samsung DVM S/S2 (E416 sibling)
  • Samsung WindFree Premium R-32 service manual (via SplitAtlas)
  • Samsung DVM S / DVM S2 service manuals (E416 sibling, via Snowflake Aircon + ManualsLib)

Match the model on your equipment label to the linked manufacturer documentation. The same code can mean different things across model families.

Quick answer

C416 is a discharge temperature (DIS-TH) sensor error - the compressor discharge thermistor is open, shorted, or reading outside its allowed window. Clean filters and one breaker reset are the safe DIY steps; sensor and refrigerant work is technician-only.

Severity: medium · 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 C416 means

C416 means an outdoor discharge temperature (DIS-TH) sensor error per the SplitAtlas WindFree Premium R-32 manual table. Samsung's own DVM service manuals list the sibling code E416 as a discharge temperature sensor error (open/short), and some model-family rows describe it as a compressor discharge over-temperature protection stop - same thermistor circuit, threshold logic varies by family.

Code meaning varies by series

  • Samsung WindFree Premium R-32 service manual (via SplitAtlas): C416 = Discharge temperature (DIS-TH) sensor error
  • Samsung DVM S / DVM S2 service manuals (E416 sibling, via Snowflake Aircon + ManualsLib): E416 = compressor discharge over-temperature protection / discharge temperature sensor error - protection-stop reading in some model families

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.
