Gree AC Error Codes

Gree Ac Error Codes & Troubleshooting Method

C5: Malfunction of connector jumper: Check if the connector jumper contacts properly. If the PCB is to be replaced, please take off the old for the new PCB

F1: Malfunction of indoor ambient temperature sensor:Check if indoor room temperature sensor is connected properly.

F2: Malfunction of evaporator temperature sensor:Check if the evaporator temperature is connected properly.

H1: Defrosting:It is normal

H6: Indoor fan block:Check if terminal of the indoor motor is connected properly. Replace the fan motor or the indoor board if disabled.

1. The wiring terminal between indoor evaporator temperature sensor and controller is loosened or poorly contacted;
2. There’s short circuit due to the trip-over of the parts on controller;
3. Indoor evaporator temperature sensor is damaged
4. Main board is broken.

Gree AC Error Code: F3

Malfunction Name: Outdoor ambient temperature sensor is open/ short-circuited

A/C Status: The unit will stop operation as it reaches the temperature point. During cooling and drying operation, compressor stops and indoor fan operates; During heating operation, the complete unit stops operation.

Possible Causes:

1. The wiring terminal between outdoor ambient temperature sensor and controller is loosened or poorly contacted;
2. There’s short circuit due to the trip-over of the parts on controller;
3. Outdoor ambient temperature sensor is damaged
4. Main board is broken.

Gree AC Error Code: H6 

Malfunction Name: PG motor (indoor fan motor) does not operate

A/C Status: Indoor fan, outdoor fan, compressor and electric heat tube stop operation. 2 minutes later, 4-way valve stops; horizontal louver stops at the current position.

Possible Causes:

1. The feedback terminal of PG motor is not connected tightly.
2. The control terminal of PG motor is not connected tightly.
3. Fan blade rotates roughly due to improper installation.

A/C Status: Operation of remote controller or control panel is available, but the unit won’t act

Possible Causes: Controller is damaged.

Gree AC Error Code ANd Troubleshooting: E2 

Malfunction Name: Antifreezing protection

A/C Status: During cooling and drying operation, compressor and outdoor fan stop while indoor fan operates.

Possible Causes:

1. Poor air-return in indoor unit;
2. Abnormal fan speed;
3. Dirty evaporator;
4. System is normal but the indoor tube temperature sensor is abnormal, or the tube temperature sensor is not connected well.
