Midea air conditioner shows what s going on with PD

High Voltage Protective Action (PD) sensor "22".

Midea air conditioner display fault**PD represents the compressor current overload protection, which may cause overload when its refrigeration pipeline is blocked, or when the compressor output pipeline is in a high pressure state. Troubleshooting method: 1. Check whether the plug of the compressor overload protector on the short-circuit electronic control motherboard is damaged, if there is no problem, but the air conditioner still shows a fault, it can be judged that the air conditioner motherboard is faulty.

Solution: You need to replace the main board of the air conditioner. 2. Use a multimeter to detect whether the compressor overload protector is normal at room temperature, if the overload protector is detected as an open circuit, it can be judged that the overload protector is damaged.

Solution: Check whether the performance resistance of the compressor is normal, and whether the performance system is dirty and blocked, and deal with it according to the situation, if the situation is serious, you can choose to replace the overload protector. Types of faults in Midea air conditioners:

1. Refrigeration system blockage: It often occurs at the capillary tube and filter drier, because these two places are the narrowest places in the system. Second, the refrigeration system leaks:

The carrier of air conditioning refrigeration and heating is the refrigerant, if the system leaks, the refrigerant leaks the air conditioning refrigeration is poor or not refrigerated at all, and the leakage of the air conditioner is mainly concentrated in the welding head of the two devices, the capillary welding, the compressor suction and exhaust pipe, the bell mouth, the copper sodium crack, the connecting pipe, etc., to check the visual inspection first, focusing on the inspection of the joints of the connecting pipe, the leakage generally has oil traces. Three, four-way valve failure: usually occurs when heating, the four-way valve is not good, gas or stuck, resulting in poor heating performance, in the judgment of the four-way valve can be turned off to listen to whether the suction is good, in the maintenance can be repeatedly energized to the four-way valve or gently knocked on the four-way valve to reset it.

Fourth, check valve failure: check valve in the refrigeration directly on, but in the heating of the refrigerant through the auxiliary capillary, when the check valve seal is not tight or the auxiliary capillary is blocked, heating is affected, so if the air conditioning refrigeration is normal but the heating is poor, after eliminating the problem of the four-way valve, it is necessary to focus on checking the check valve.

Summary. Midea Air Conditioner Failure**PD indicates compressor failure. Troubleshooting methods: 1. Short-circuit the plug of the compressor overload protector on the electronic control motherboard, if the air conditioner still reports a fault, it can be judged to be a fault of the air conditioner motherboard and needs to be replaced.

Midea's air conditioner failure**PD table Wang sedan is indicating the failure of the pressure sail shrinking machine. Troubleshooting methods: 1. If the air conditioner still reports a fault, it can be judged that the air conditioner motherboard is faulty and needs to be replaced.

Can there be a ** reminder thank you.

No, oh dear. PD**: Compressor failure.

Its base cherry blossom is mainly caused by the following reasons: 1. The failure of the intake filter: the fouling and blockage of the Midea air conditioner appears PD, and the air conditioner shows PD indicating that the compressor is faulty, and the piston compressor current overload protection is known.

It may be due to the overload of the compressor, check or the fault of the main board of the air conditioner and need to replace the seepage, start to see it is recommended to find a professional repairman to call the cong staff to replace it, and avoid damage caused by the process of disassembly and assembly outdoors.

PD**: Compressor failure. It is mainly caused by the following reasons:

1. Failure of the intake filter: fouling and blockage, increase and decrease the sensor to reduce the exhaust volume by 1The plug-in of the compressor overload protector on the short-circuit electronic control motherboard shows PD of the vertical air conditioner, if the air conditioner still reports a fault, it can be judged as a fault of the main board of the air conditioner; Workaround:

It needs to be replaced. 2.At room temperature, use a multimeter to detect the compressor overload protector, what does the temperature condenser mean that the suction is too high, if the overload protector is liquid-off, guess the key, and the Lumei air conditioning cabinet shows PD, it can be judged that the overload protector is damaged.

Solution: Check whether the performance resistance of the compressor is normal and whether the performance system is dirty and blocked; Whether it needs to be replaced.

For this kind of question, it is more useful to read the manual than to ask a question.

On the manual, there are clear instructions for the flashing status of different indicators and different faults, which are accurate and reliable.

If there is a solution that can be used, the manual will also have a detailed process, as well as an accurate schematic diagram, and how to operate.

Generally, Biliangmei's air conditioner shows that the PD is the fault of the air outlet, and your first step is to unplug the compressor power supply, and then check if there is something blocked in the air outlet Huisou, which makes the air outlet blocked.

Hello: Midea's crosswind built-in air conditioner will display the fault of PD**, and the meaning of fault ** is four current protection.
