The air conditioner compressor does not work, but the fan of the external unit works, please , how

There are the following reasons why the air conditioner compressor is not working:

Common faults of air conditioning compressors include abnormal noise, leakage and non-operation. First: There are many reasons for abnormal noise to cause abnormal noise of air conditioning compressors.

For example, the electromagnetic clutch of the air conditioning compressor is damaged, or the internal wear of the compressor is serious, etc., can produce abnormal noise. The compressor electromagnetic clutch is a common part of the abnormal noise. The air conditioning compressor often runs from low speed to high speed under high load, so the requirements for the electromagnetic clutch are very high, and the installation position of the electromagnetic clutch is generally close to the ground, and it is often in contact with rain and mud, and when the bearing in the electromagnetic clutch is damaged, it will produce abnormal noise.

In addition to the problems of the electromagnetic clutch itself, the tightness of the transmission belt of the air conditioning compressor also directly affects the life of the electromagnetic clutch. If the transmission belt is too loose, the electromagnetic clutch is prone to slippage; If the transmission belt is too tight, the load on the electromagnetic clutch will increase. Improper tightness of the transmission belt will cause the compressor to not work, and at worst it will cause damage to the compressor.

When the transmission belt is working, if the compressor pulley and the generator pulley are not in the same plane, the life of the transmission belt or compressor will be reduced. Repeated engagement of the electromagnetic clutch will also cause abnormal noise in the air conditioning compressor. For example, insufficient power generation from the generator, high pressure in the air conditioning system, or excessive engine load can cause the electromagnetic clutch to engage repeatedly.

There should be a certain gap between the electromagnetic clutch and the installation surface of the air conditioning compressor, if the gap is too large, then the impact will also increase, if the gap is too small, the electromagnetic clutch will work with the compressor installation surface between the motion interference, which is also a common cause of abnormal noise. Air conditioning compressors require reliable lubrication when they work. When the air conditioning compressor lacks lubricating oil, or the lubricating oil is used improperly, there will be serious abnormal noise inside the compressor, and even cause the compressor to wear and scrap.

Second: Leaking Refrigerant: Leakage is the most common problem in air conditioning compressor systems.

The leakage of the air conditioner compressor is usually at the junction of the compressor and the high and low pressure pipes, which is usually troublesome to check because of the installation location. The internal pressure of the air conditioning system is very high, and when the refrigerant leaks, the compressor lubricating oil is lost with it, which leads to the air conditioning system not working or the lubrication of the compressor is poor. There are pressure relief protection valves on the air conditioning compressors, and the pressure relief protection valves are usually used once, and the pressure relief protection valves should be replaced in time after the system pressure is too high for pressure relief.

Third: There are many reasons why the air conditioner compressor does not work, usually because of the problem of the related circuit. The compressor can be preliminarily checked for damage by supplying direct power to the compressor's electromagnetic clutch.

You first see if the wire end of the starting capacitor has a burnt section, if not, change the capacitor to see if it is OK, if not, open the top cover of the compressor to see if the wire head is burned, not yet, the pressure is too high, let go of some potion, if it is not good, check whether there is 220V electricity at the power supply end of the compressor, if not, there is a problem with the computer board of the internal machine, and then don't repair it and buy a new one.

1: Compressor failure.

2: The control circuit is damaged. 3: Refrigerant leakage system problem.

<> reasons why the air conditioner compressor does not work are:

1. When using the air conditioner, there is a sudden power failure or the power supply of the air conditioner is suddenly loosened, and the air conditioner compressor cannot work normally at this time.

2. If the voltage is not enough, it will lead to shutdown, first check whether the voltage reaches the rated voltage, if the voltage is not enough, the compressor will not work.

3. The refrigerant of the air conditioner is insufficient.

When using air conditioners, if the air conditioner product has insufficient refrigerant, then the air conditioning compressor will also fail in this state, and the air conditioning compressor will not work. If the air conditioner compressor does not work due to insufficient refrigerant, then only the refrigerant needs to be added to the air conditioner.

4. The air is not discharged during the installation of the air conditioner.

When we install the air conditioner, if the air in the air conditioner is not excluded clean, there will be ice blockage, the load of the air conditioning compressor will increase, the temperature will continue to increase, the refrigeration oil in the air conditioning compressor is easy to deteriorate in such a high temperature situation, and the air conditioning compressor will not play the role of lubrication and cooling of the air conditioning compressor, and the temperature of the air conditioning compressor will rise to too high a temperature, which will lead to the reduction of the insulation performance in the most coil. Eventually, it will cause damage to the air conditioner compressor and make the air conditioner compressor not work.

**The internal and external fan bureau of the empty tung liquid adjustment is running normally, and the compressor is not working, it may be that the compressor is faulty, and you can ask professionals to repair it. Blind travel.

It may be because of the lack of engine oil, go outside to buy some oil and apply it to the compressor, wait for the compressor to lubricate and then use it normally.

Because each part of the air conditioner has its own work Hengkai's efficiency, all have their own certain functions, if this situation may occur, the noise is a problem with the compressor, the setting of the air conditioner is not very correct, and the air conditioner lacks oil.

It may be because the mode of use of the air conditioner is incorrect, it may be that the accessories of the driver are born and damaged, it may be because the temperature is too high, but it can be because the temperature sensor is short-circuited.

After the air conditioner has been used for a long time, or the installation process is not in place, it may cause the fan of the air conditioner to not rotate. If such a problem occurs, you should find a professional maintenance personnel to repair it. The maintenance methods are described below

Cause. 1. Poor contact of the main control switch.

Maintenance method: Use a multimeter to measure the contact resistance of the main control switch, when the resistance is too large or zero, it should be repaired or replaced.

Cause. Second, the fan motor coil is damaged.

Maintenance method: Use a multimeter to measure the contact resistance of the main control switch, when the resistance is too large or zero, it should be repaired or replaced.

Cause. 3. The set screw between the motor of the fan and the fan blade is loose.

Maintenance method: Tighten the set screws.

Cause. 4. The fan capacitor is open or short-circuited.

When the air conditioner cannot work, the first thing we should check when inspecting is that the heat dissipation effect of the condenser of the air conditioner is very good, and when the heat dissipation effect of the air conditioner's condenser becomes poor, the air conditioner will be overheated for protection.

There is a reward to write that the air conditioner compressor works but the external fan does not turn how to repair? There are incentives to write about the maintenance of household appliances, and the life home focuses on the repair, maintenance, and development trend of household appliances. Follow to become the 2032nd fan: air conditioner compressor running fan does not run possible faults are as follows.

First. The external fan is faulty. If the fan motor coil is damaged and the external fan does not run, this situation can only be replaced or the liquid is repaired by the motor.

Second. The starting capacitor of the external shed pin fan is damaged or the capacity is insufficient. Replace the external fan directly, and the starting capacitor can be repaired.

Third. The connection line of the internal and external units is damaged, resulting in the failure of power supply to the capacitor of the fan. Causing the fan to be unable to operate.

In this case, it is enough to replace the connecting cable of the internal and external machine. Fourth. The motherboard of the internal machine is faulty.

The internal motherboard does not supply power like the external fan, which means that the relay of the internal motherboard is damaged, or the CPU program is chaotic and cannot supply power to the external imitation machine. In this case, it can only be repaired or replaced with the motherboard of the internal machine.

What is a CPU.

It is the air conditioner processor, which is a major component.

There are many possible reasons why the fan of the outdoor unit of an air conditioner does not turn and the compressor is running, and here are some common reasons:

Fan motor failure: If the fan motor is damaged or malfunctioning, the fan will not work properly. This can be caused by a circuit problem, a burned motor winding, or a worn bearing on the ruler plexiculturer.

Stuck or deformed fan blades: If the fan blades are stuck by debris or deformed by impact, the fan will not rotate properly.

Faulty circuits: The circuitry of the outdoor unit of the air conditioner may be faulty, such as damaged switches, relays, or fuses, etc., which may cause the fan to not work properly.

Faulty capacitor on the fan: The capacitor on the fan may fail, causing the fan to fail properly.

Faulty control board: Components on the control board may fail, causing the fan to fail properly.

The above are some of the common reasons, but this is not an exhaustive list. If you encounter the problem that the fan of the outdoor unit of Zhengyan air conditioner does not turn and the compressor runs, it is best to ask professional and technical personnel for maintenance and maintenance.

Hello dear, happy to solve the problem for you, <>

The compressor of the external unit does not work; 1. The remote control mode is incorrect Check whether the remote control is set to refrigeration mode. Using the remote control of the air conditioner, adjust the mode to a state that shows "cooling" or "snowflake" and set the temperature to 26 degrees or below. 2. Power supply problem: Pay attention to whether the outdoor unit has working sound (including the outdoor unit, only the fan and the compressor).

If the outdoor unit fan is running, the control circuit is basically normal. At this time, you should observe whether the compressor starts or not, and if the compressor does not start, you should check whether the power supply is normal. 3. The reason for the voltage There are many reasons why the voltage is not enough, so I won't say much here, if the air conditioner can't be turned on, it is necessary to check whether the power supply of the external unit is electric or whether the voltage reaches the rated voltage.

If it is not the cause of low voltage, please check whether the indoor and outdoor units are connected correctly, whether the wires are aging, and whether the motherboard of the indoor unit is wired correctly, otherwise replace the motherboard of the internal unit.
