Gree air conditioners display error codes on their LED screens to indicate issues with indoor and outdoor units. Refer to your manual or our error code list for troubleshooting. For your specific model, refer to the owner's manual or our comprehensive Gree air conditioner error code list below. Our technicians can handle repairs for problems like refrigerant leaks and sensor or thermostat issues.
Gree E Series Error Codes
| Error Code | Means |
| E1 | High pressure protection in refrigerant systems keeps them safe by monitoring and controlling excessive pressure, using sensors and valves to prevent damage and hazards. |
| E2 |
Prevents freezing when the system is in cooling mode. |
| E3 | Not enough refrigerant in the system. |
| E4 | Protection against high temperatures in the compressor exhaust. |
| E5 | Safety feature that prevents too much electrical current in the air conditioner. |
|
E6 |
Failure in communication between the indoor and outdoor units of the system. |
| E8 |
Error E8 on your air conditioner usually means there's a problem either with the indoor fan motor or with the indoor circuit board. |
| E9 | E9 means there's a water flow switch issue; after it happens 3 times in 60 minutes, you need to manually restart the system before it can run again, and all units stop running. |
| EE | There is an issue with the process of loading data into the EEPROM memory. |
| ee | There is an issue with the process of loading data into the EEPROM memory. |
| EU | The IPM is getting too hot, so it's reducing its operating frequency. |
Gree F Series Error Codes
| Error Codes | Means |
| F0 | F0 indicates that there is not enough refrigerant in your split air conditioner. It's important to have a certified F-gas engineer fix this issue, as it's required by law in Europe. |
| F1 | The indoor unit's ambient temperature sensor is either open or has a short circuit, causing a malfunction. |
| F2 | The sensor that measures the temperature of the indoor unit's evaporator might be broken, have a wiring issue. |
| F3 |
The sensor that measures the outdoor temperature might have a broken wire or a short circuit. |
| F4 |
The sensor on the outdoor unit's tubing might have a broken wire or a short circuit. |
| F5 | The sensor that monitors the exhaust may have a broken wire or a short circuit. |
| F6 | It seems like there might be an issue with the overload limit or drop frequency. |
| F8 | It appears that there could be a problem with the overcurrent limit or the drop in frequency. |
| F9 | The high exhaust temperature limit may cause a decrease in frequency. |
| FA |
The frequency drops due to the over-temperature of the tube. |
| FC | There is a problem with the door not functioning correctly. |
| FE | The sensor that detects compressor overload is not working properly. |
| FH |
The frequency drops due to reaching the anti-freezing limit. |
Gree H Series Error Codes
| Error Codes | Means |
| H0 |
The frequency drops due to reaching the anti-high temperature limit in heating mode. |
| H1 | The system is in the process of defrosting. |
| H2 | The system is protecting itself by clearing static and dust buildup. |
| H3 | The system protects the compressor from overload. |
| H4 |
The outdoor unit's LED displays an H4 overload error when the condensing pressure is too high, typically caused by a blocked or inefficient heat exchanger. |
| H5 | Input voltage may be incorrect, outdoor unit cables need checking, compressor coil resistance might be a problem, and insulation around the compressor coil and copper pipe needs inspecting. |
| H6 | The indoor fan is blocked or there is no feedback from the indoor fan motor. |
| H7 |
The compressor is protected against operational steps or stages being lost. |
| HC | PFC protection ensures the power factor correction system is safeguarded against faults or overloads. |
| HE |
Compressor demagnetization protection prevents the compressor from losing its magnetic properties, ensuring proper operation. |
Gree L Series Error Codes
| Error Codes | Means |
| L3 | The outdoor fan motor for the air conditioner is not working properly. |
| Lc | The device is not starting up. |
| Ld | The compressor is shutting down because it's missing one of its power phases. |
| LE | The compressor is shutting down to prevent damage because its rotor is stuck. |
Gree P Series Error Codes
| Error codes | Means |
| P0 | There is an issue with resetting the drive module. |
| P5 | The compressor is shutting down because too much current is flowing through one of its phases. |
| P6 | The main board and the driver board are not able to communicate. |
| P7 | The IPM sensor circuit is not working correctly. |
| P8 | The IPM is shutting down because it is too hot. |
| PA |
Protection against excessive AC current from the input area. |
| PC |
There is a problem with either the current detection circuit or the current sensor. |
| PH |
Protection against too high voltage for PN. |
| PL |
Protection against low voltage for PN. |
| PU |
There is a problem with charging the capacitor. |
U Series Error Codes
| Error Codes | Means |
| U1 | There is a problem with the circuit that detects the current in the compressor's phases. |
| U2 | The compressor is protected from losing a phase of power. |
| U3 | Protection against a decrease in PN voltage. |
| U4 |
Protection to prevent the compressor from running in reverse. |
| U5 | There is a malfunction in the circuit that detects AC current. |
| U7 | There is an abnormal condition with the 4-way valve reversal. |
| U8 |
The exhaust temperature sensor has been disconnected. |
| U9 |
Error in detecting zero voltage in the AC power supply. |
Other Error Codes
| Error Codes | Means |
| oE | Protection due to high temperature in the PFC module or malfunction of the PFC module sensor. |
| b5 | There is a malfunction with the sensor in the inlet tube. |
| b7 | There is a malfunction with the sensor in the outlet tube. |
| C5 |
Protection against malfunctioning jumper cap. |
| C5 | There is a problem with the connector jumper. |
