The Gree air duct machine shows what fault F2 is

Gree air conditioner shows F2 indicating inner tube heating, that is, the condenser temperature sensor is short-circuited.

After the Gree air conditioner is turned on, the LCD screen shows that the F2 is faulty, and the indoor and outdoor units stop working. If the fault still appears, the detection method is as follows:

Analyze whether the indoor circuit board is faulty, and check the resistance value of the indoor room temperature sensor. If it is 15kq, it is normal, and other values are abnormal. Re-measure the resistance of the indoor tube temperature sensor, if the actual resistance is 15kq, it is normal.

Measure the voltage at both ends, and the normal value is if it is abnormal, you can determine that the indoor pipe temperature sensor is damaged, and the air conditioner shows F2.

Heating principle: The low-pressure gas inhaled by the compressor is compressed into high-temperature and high-pressure gas by the compressor, and the high-temperature gas is heated by the heat exchanger, and the high-temperature gas is condensed into liquid.

When the liquid enters the evaporator for evaporation, the evaporator also needs a heat exchange medium. According to the different heat exchange medium, the model and structure of different machines are also different. Commonly used are air-cooled and ground sources.

After passing through the evaporator, the liquid becomes a low-pressure cryogenic gas, which is again sucked in by the compressor for compression.

The side circulating water of the air conditioner becomes hot water around 45-55 degrees Celsius. Hot water is transported to the room that needs to be heated through the pipe, and the room is equipped with a fan coil unit to exchange hot water and air to achieve the purpose of heating.

If the temperature sensor package of the indoor unit tube fails, let the after-sales master come to the door for maintenance.

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

After the Gree air conditioner is turned on, the LCD screen shows F2 fault, the indoor and outdoor units stop working, unplug and turn on again, and the detection method is as follows:

Analyze whether there is a fault in the indoor circuit board, check the resistance value of the indoor room temperature sensor, if it is 15kq, 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 15kq, which is normal.

If it is not normal, it can be determined that the indoor pipe temperature sensor is damaged and the air conditioner displays F2.

Heating principle:

The compressor sucks in low-pressure gas and compresses it into high-temperature and high-pressure gas, and the high-temperature gas increases the water temperature through the heat exchanger, and the high-temperature gas will condense into liquid.

The liquid enters the evaporator for evaporation, and the evaporator evaporates at the same time, and there must be heat exchange, according to the heat exchange, the model structure of the machine is also different, and the commonly used ones are air-cooled and ground source, and the liquid becomes a low-pressure cryogenic gas after passing through the evaporator, and the cryogenic gas is sucked in by the compressor again for compression.

The circulating water on the side of the air conditioner becomes hot water at about 45-55 degrees. Hot water is sent to the room that needs to be heated through the pipe, and the room is equipped with a fan coil unit to exchange hot water and air to achieve the purpose of heating.

1. Air conditioner failure**F2 indicates that the indoor evaporator temperature sensing package is open and short-circuited. 2. The F2 of the air conditioner is generally manifested as a failure after about 5 minutes of start-up**, and at the same time, the indoor and outdoor units stop working, which is generally a temperature sensor failure, and a new tube temperature sensor can be replaced.

What does the air conditioner mean when it shows f2.

Gree air conditioner shows that F2 is the indoor evaporator temperature sensing package open, short circuit, the specific cause of the fault needs to be detected and dealt with by service personnel, please click "Appointment Service" or call the national unified after-sales service** feedback your suggestions and needs.

The air conditioner shows F2 is generally a problem with the condenser temperature sensing head of the air conditioner, if the air conditioner is within the warranty period, contact the manufacturer directly for maintenance. If the air conditioner exceeds the warranty period, you can remove the air conditioner shell to detect whether the temperature sensor head is short-circuited or damaged, if the temperature sensor head is damaged, you only need to replace the temperature sensor head again, or you can find a professional maintenance master for maintenance.

Re-measure the voltage at both ends as, abnormal, normal value. Therefore, it is clear that the indoor pipe temperature sensor is damaged, and the air conditioner shows F2, and the power supply will return to normal after replacing the new indoor pipe temperature sensor.

Precautions for the use of air conditioners.

Choose an air conditioner with moderate cooling power. An air conditioner with insufficient refrigeration power can not only not provide sufficient cooling effect, but also shorten the service life of the air conditioner and increase the possibility of air conditioner failure due to long-term uninterrupted operation.

If the refrigeration power of the air conditioner is too large, the thermostat of the air conditioner will be turned on and off too frequently, which will lead to increased wear and tear on the air conditioner compressor; At the same time, it will also cause an increase in the power consumption of the air conditioner.

The reasons for the failure of Gree F2** are as follows1. 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 and the air conditioner displays F2, and it is recommended to find a special maintenance personnel to repair the replacement parts.

3. Use a universal meter to detect the outdoor coil, scattered rock may also be the fault of the outdoor coil sensor, detect the value, judge whether it is broken, and if the detection sensor is normal, it is a computer board failure. Gree Air Chong Lu Yu Fault **F2 Solution Replace the air conditioner with a new tube temperature sensor, and then turn on the machine to return to normal.
