How much does it cost to repair the Gree F3

Gree's fault**F3 indicates that the air conditioner has a faulty indoor unit outlet temperature sensor.

The solution is to ask a professional air conditioner maintenance master to come and repair it.

Common air conditioner failures** are as follows:

E1 represents compressor high pressure protection, E2 represents indoor unit anti-freezing protection, E3 represents compressor low pressure protection, E4 represents compressor discharge temperature protection, E5 represents compressor overcurrent protection, and E6 represents abnormal communication.

F0 indicates that the room temperature sensor is faulty, F1 indicates that the temperature sensor of the indoor unit is faulty, F2 indicates that the temperature sensor in the middle of the indoor unit is faulty, F3 indicates that the temperature sensor of the indoor unit is faulty, and F4 indicates that the ambient temperature sensor of the outdoor unit is faulty.

F5 indicates the failure of the inlet temperature sensor of the outdoor unit, F6 indicates the failure of the temperature sensor in the middle of the outdoor unit, F7 indicates the failure of the outlet temperature sensor of the outdoor unit, F8 indicates the failure of the compressor exhaust temperature sensor (constant volume machine), and F9 indicates the failure of the compressor exhaust temperature sensor (digital machine);

FA indicates oil temperature sensor failure (volume control machine), FB indicates oil temperature sensor failure (digital machine), FC indicates high pressure valve failure, and FD indicates low pressure valve failure.

The cost depends on the parts you replace and the service.

If F3 occurs, the temperature sensor of the outlet pipe of the indoor unit is faulty.

The reasons are as follows: 1. The power module of the outdoor unit is damaged by heating and short circuit.

2. The power supply of the inverter module is abnormal.

3. The capacity of the boost filter capacitor is insufficient.

4. The main control board of the outdoor unit is a hail obstacle.

5. The power supply of the external unit is abnormal.

6. The external machine is resistant to abnormal communication.

7. There is a problem with the extension code setting.

8. There is a lot of dust in the net, and it is dirty.

9. The internal evaporator is dirty and blocked.

Solution: 1. If the indoor temperature has reached the set temperature, the air conditioner will not work, just adjust the air conditioner temperature.

2. The control compressor and cooling fan contactor are damaged and need to be repaired.

3. If the refrigerant is insufficient, just add it.

4. The circuit board is damaged, there is no output signal, and it needs to be repaired.

5. Overheating protection of the air conditioner, stop using it for one hour and then try to start.

6. The cooling fan itself and related wiring are faulty and need to be reported for repair.

The fault of Gree air conditioner shows that F3 is the opening and short circuit fault of the outdoor environmental temperature sensing package.

Here's how to detect faults:

1. Check whether the wiring is loose.

2. Check whether the sensor line is disconnected.

3. Check whether the sensor is faulty and the resistance value of the sensor is drifting.

4. Check whether the control circuit board is faulty.

1. It may be a communication failure: this situation is usually the signal line of the internal and external machine is broken or leakage, it is recommended to check whether the black connection line between the internal unit and the outdoor unit is loose, and tell the relatives to replace the indoor and outdoor Jane friends to accompany the connection signal wire and try the machine again.

2. It may be that the motor is stalled or the motor does not rotate fault: this situation is usually the fault of the air conditioning line, especially in public places such as restaurants, it is recommended to check whether there is a problem with the line. If there is no problem with the wire, observe whether the wire on the terminal block is connected incorrectly.

And turn it back on after disconnecting the power supply.

3. It may be that there are debris in the air conditioner: in this case, it is usually necessary to turn off the main power, open the lower cover, pull out the filter to clean and clean the electrostatic precipitator with a brush. It is also necessary to check whether the refrigeration line is blocked, and if it is blocked, the pipe needs to be cleaned.

F3: The outlet temperature sensor of the indoor unit is faulty.

Causes: 1. The power module of the outdoor unit is heated and damaged by short circuit.

2. The power supply of the frequency conversion module is abnormal.

3. The capacity of the boost filter capacitor is insufficient.

4. The main control panel of the outdoor unit.

5. The power supply of the external unit is abnormal.

6. Communication failure of the external machine.

7. Problem with extension code setting.

8. The net is dusty and dirty.

9. The internal evaporator is dirty and blocked.

Solution: 1. If the indoor temperature has reached the set temperature, the air conditioner will not run, and you only need to adjust the temperature of the air conditioner.

2. The contactor controlling the compressor and the cooling fan is damaged and needs to be repaired.

3. If the refrigerant is insufficient, add it.

4. The circuit board is damaged, there is no output signal, and it needs to be repaired.

5. Air conditioner overheating protection, stop using for one hour and then try at start.

6. The heat dissipation fan itself and related wiring faults need to be repaired.

1. First of all, observe whether the air outlet volume of the air conditioner becomes smaller;

2. Then open the inner machine to see if the filter screen is blocked by dust, and if so, clean it with clean water;

3. If there is no problem with the air outlet volume and filter screen of the air conditioner, it means that the pipe temperature head is damaged, and the pipe temperature head can be replaced.
