Gree Mini Split F5 Error Code

Updated 2026-08-29 · review status: manual-verified · reviewed by MiniSplitDecoder Editorial Team Last verified: 2026-08-29

Check your model first

  • Livo / R32 residential splits (manual-aligned)
  • Some older wall-mount ranges

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

Quick answer

F5 means the compressor discharge temperature sensor is reading open, short, or out of range, so the unit protects the compressor by stopping. Some Gree ranges shift the F-series and map F5 to the wired-controller sensor. Either way, diagnosis is technician-only.

Severity: high · DIY difficulty: easy

Safety

Stop at the single power-cycle check. Discharge-sensor circuits sit on or near the compressor inside the outdoor cabinet - do not open panels, test sensors, or connect gauges. Technician-only.

What F5 means

F5 means the compressor discharge temperature sensor circuit is open, shorted, or out of range, and the unit stops to protect the compressor. On some Gree ranges the F-series shifts by one and F5 instead identifies the wired-controller temperature sensor. Both are sensor-circuit faults for a technician.

Code meaning varies by series

  • Livo / R32 residential splits (manual-aligned): Compressor discharge temperature sensor malfunction
  • Some older wall-mount ranges: Wired-controller internal temperature sensor fault (F-series shifted by one)

Causes, ranked

  1. 1. Compressor discharge temperature sensor open or shorted common pro only

    Check: Needs resistance measurement against the manual sensor table at the compressor head.

    Fix: Technician: test and replace the discharge sensor if out of spec.

  2. 2. Genuinely high discharge temperature from low charge, overcharge, or airflow restriction occasional pro only

    Check: Requires gauge readings and superheat/subcooling calculation.

    Fix: Technician: verify charge and airflow; fix the underlying cause.

  3. 3. Loose or corroded discharge-sensor connector occasional pro only

    Check: Connector sits inside the outdoor electrical section.

    Fix: Technician: reseat or repair the connector.

  4. 4. Outdoor board sensor-input fault after the sensor tests good rare pro only

    Check: Board-level diagnosis only.

    Fix: Technician: diagnose the outdoor PCB; replace board if faulty.
