Hello, everyone. Lin Fei has come to answer the above questions. How to collect freon if the outdoor unit of the air conditioner does not work, and many people do not know if the outdoor unit of the air conditioner does not work. Now let's take a look!

Nowadays, air conditioning is a necessity for every family. When we are in the hot summer, the air conditioner can bring us cool, when we are in winter, the air conditioner can bring us warmth. So with air conditioning, our life is really warm in winter and cool in summer, very comfortable.

In fact, there are many reasons why the external air conditioner does not work. Let Benshaw give you some reasons. You should listen carefully.

1. The reason why the external unit of Gree air conditioner does not work.

First, the voltage is low or the line is aging.

Second: the electric buzzer does not ring, please check the transformer.

Third, the red light of the external unit is not lit.

Fourth, the external machine has a power supply, the red indicator light is on, and the external machine does not start. Communication between the internal machine and the external machine can be checked.

Fifth, the air conditioner will be on for about 10 minutes, but it won't.

Sixth, the external environment of the air conditioner is hot and the air conditioner cannot be started.

Second: the solution that Gree air conditioning does not work.

1: check whether the external power supply has electricity or whether the voltage reaches the rated voltage. If the voltage is not low, please check whether the indoor unit and outdoor unit are connected correctly, the wires are aging, and the wiring of the indoor unit motherboard is correct, otherwise replace the indoor unit motherboard.

two。 If the voltage of the external device is 220V, check if the red LED on the motherboard of the external device is lit. If the LED is not on, check that the connection of the external unit is loose and that there is a DC voltage of about 300V between the power supply module P and N -. If not, check the reactor, rectifier bridge and wiring. If there is, but the external extension motherboard indicator is not on, first check whether the signal connection cable from the power module to the motherboard (a total of 10) is loose or poor contact. If it fails again, replace the power supply module. When replacing the module, the radiator and the module must be evenly coated with heat dissipation paste.

3: (check method: press the "test" button once after turning on to observe the indoor unit indicator light. Any kind of light flashes normally, otherwise there will be communication problems; check whether the connection line between internal and external machines is a special soft cable, if not, replace it in time to avoid similar situation. If the communication is normal, please check whether the temperature sensors of the indoor and outdoor units are open or short-circuited or the resistance is abnormal, and whether the ports of the overload protector are connected correctly. If none of the above methods can solve the problem, please replace the outdoor controller.

4: please check whether the indoor tube temperature bulb is on; if the external fan is not activated, check whether the indoor and outdoor temperature sensors are short-circuited.
