What is the reason why the Gree air conditioner shows that after a few days of f2, the refrigeration

The refrigeration panel of Gree air conditioner shows F2, which is because the temperature sensor of the indoor evaporator is open or short-circuited.

Based on your fault description, there are two possible reasons:

1. The reliability of the air conditioning detection circuit board is poor, and the indoor evaporator temperature sensing package is not detected, and the fault phenomenon is that it is not working, and there are few times when it is not working;

2. The wiring of the indoor evaporator temperature sensing package is unreliable, and the fault phenomenon is also sometimes ineffective, and there are many times when it is not working.

If the fault occurs frequently, it is recommended to find a professional maintenance personnel.

Gree air conditioner F2 means that the temperature of the inner tube is open, that is, the condenser temperature sensing head is faulty and short-circuited.

The condenser thermometer head needs to be replaced.

When the temperature sensing head is replaced, the air conditioner opens the panel, and the filter on the right side is removed, and you can see that there is a black lead, which is the temperature sensing head.

Then connect it to restore the insulation.

That's because the indoor thermostat is short-circuited, and the shutdown may be restored when it is turned on

What's going on with the Gree air conditioner showing F2? How to solve it?

After the power on, the LCD screen shows that the F2 is faulty, and the indoor and outdoor units stop working, and then turn on the machine after unplugging, and the fault phenomenon is the same. Reason: Gree air conditioner shows F2, which means that the temperature of the inner tube is open, that is, the condenser temperature sensor head is faulty and short-circuited.

1. First of all, analyze whether there is a fault in the indoor circuit board, check the resistance value of the indoor room temperature sensor, if it is 15k, it is normal, and other values are abnormal. Re-test the resistance value of the indoor tube temperature sensor, and the actual resistance value is 15k, which is normal. 2. Measure the voltage at both ends, the normal value is, if it is not normal, it can be very sure that the indoor pipe temperature sensor is damaged, which causes the air conditioner to display the outdoor coil with a universal meter to detect the outdoor coil, or it may be the failure of the outdoor coil sensor, detect the value, judge whether it is broken, and the detection sensor is normal if it is a computer board failure.

Gree air conditioner failure**F2 solution The air conditioner is replaced with a new tube temperature sensor, and then it can be turned on to return to normal. It is recommended that you find a special maintenance personnel for maintenance to replace parts, and if the circuit board is faulty, it is more necessary to repair the operation.

Gree air conditioner shows F2's solution to the family's hunger:

1. Check the power supply first.

The performance of the Gree air conditioner with power supply is that when it is just powered on, it will make a very crisp "beep" sound, then the air conditioner power supply is normal, and then see if the air conditioner remote control has a battery or whether the battery power is enough.

2. Check whether the connecting line is broken.

It may be because the connection cable between the indoor unit and the outdoor unit has been bitten off by mice, and the contact staff can run normally if it is connected.

3. No maintenance for a long time.

Long-term non-maintenance will make the outdoor unit of the air conditioner unable to operate normally and prompt F2 failure, which needs to be maintained or cleaned up for normal use.

4. The ambient temperature is too high, resulting in system protection.

When the ambient temperature is too high, the outdoor unit has poor ventilation and a mesh cover or the wall is blocked in front of the outdoor unit, the heat of the air conditioner cannot be blown out, and the temperature is too high, the compressor will automatically start the protection, and only need to suspend the use for 30 minutes to one hour and restart it to solve the problem.

5. The reason for voltage.

Check that the voltage is up to the rated voltage. If it is not the cause of low voltage, please check whether the indoor and outdoor units are connected correctly, and whether the wiring is wrong due to the mobile air conditioner.

6. The inspection is the communication between the internal machine and the external machine.

If the outdoor unit has a power supply, the red indicator light is on, and the external unit does not start, you can check that it is the communication between the internal unit and the external unit, and any kind of light flashing is normal.

7. Caused by insufficient operation of Freon.

The root cause of refrigerant insufficiency. Solution: Replenish the air conditioner with freon.

8. Hardware failure.

Gree air conditioner showing F2 is usually caused by the following reasons:

1.Humidity sensor failure: The humidity sensor is an important component to control the humidity of the air conditioner, if the sensor is damaged or malfunctioning, the air conditioner will malfunction**f2. The solution to do is to replace the humidity sensor.

2.Fan failure: The fan of the air conditioner is used to circulate air, if the fan is damaged or does not run smoothly, it will cause the air conditioner to work abnormally and malfunction**F2. The workaround is to clean or replace the fan.

3.Control Board Failure: The control board is the main control center of the air conditioner, and if the control board fails, it may cause the display of F2 to fail**. At this time, the control board needs to be overhauled or replaced by professional technicians.

4.Faulty sensor circuits: The sensor circuits of the air conditioner connect the sensors to the control board, and if the wires are damaged or loose, it will also cause the display of F2 faults**. The solution is to check the line connection and repair or replace the damaged line.

If you have any questions about air conditioning, you can consult Gree! Products and services are the most direct embodiment of enterprise quality management, and they are also the most direct way for consumers to recognize the brand. Gree Electric adheres to the guidance of consumer demand and consumer satisfaction as the standard, and Yeyuan took the lead in the industry as early as 2005 to launch the policy of "6-year free repair of household air conditioner" to upgrade the service quality.

In 2021, Gree announced the implementation of a "ten-year warranty policy" for household air conditioners to protect the interests of consumers to a greater extent.
