In brief
Fault code F0 on Gree Lomo / Fairy / Bora means: Fault code F0 is specific to Gree. It is a protection: the system detects that heat exchange is not occurring correctly (often due to a lack of gas or a blocked capillary) and shuts down to prevent compressor damage. The air conditioning then blows warm air. Most common cause: Refrigerant leak (cause #1), blockage in the refrigeration circuit (capillary), or a displaced room temperature sensor. Must be checked by an F-Gas registered engineer. First action: Check flare connections for oil traces.. Call a registered engineer if the fault returns after basic checks or involves refrigerant work (F-Gas registered engineer required).
According to the Gree Service Manual, F0 is triggered when the discharge temperature sensor detects abnormal heat exchange, often due to a refrigerant shortage.

Gree Fault Code F0: Refrigerant Shortage — Causes
Fault code F0 is specific to Gree. It is a protection: the system detects that heat exchange is not occurring correctly (often due to a lack of gas or a blocked capillary) and shuts down to prevent compressor damage. The air conditioning then blows warm air.

What does fault code F0 on Gree mean?
Fault code F0 is specific to Gree. It is a protection: the system detects that heat exchange is not occurring correctly (often due to a lack of gas or a blocked capillary) and shuts down to prevent compressor damage. The air conditioning then blows warm air.
Refrigerant leak (cause #1), blockage in the refrigeration circuit (capillary), or a displaced room temperature sensor. Must be checked by an F-Gas registered engineer.
Symptômes
- The air conditioner blows warm air in cooling mode
- Ice on the indoor heat exchanger
- Compressor stops
Diagnostic
1. Leak Check
- Check flare connections for oil traces.
- Connect manifold gauges: if pressure is abnormally low, there is a leak.
2. Sensor Check
- Occasionally, a poorly calibrated sensor can mislead the control board, but this is rare for F0.
How to reset fault code F0 on Gree?
Find the leak, repair it, and recharge the gas. If the circuit is blocked, replace the capillary tube.
When should you call an F-Gas engineer?
Often occurs during seasonal transitions or after an unrepaired micro-leak.
Affected models
- Split Gree
- GMV
Field context
Often occurs during seasonal transitions or after an unrepaired micro-leak.
Technical source data
Gree F0 indicates a refrigerant protection / discharge temperature sensor check. Verify sensors, gas charge and expansion valve before intervening on the compressor.
Questions fréquentes
Can I recharge the gas myself?
No, handling refrigerants requires a certificate of competence. In the UK as in France, an F-Gas registered engineer must carry out the work.
