How do you know if the compressor of the air conditioner is broken?

The quality of the compressor is not clear in one or two sentences, even if it is a professional person, it can only be measured by a certain instrument. However, some maintenance personnel can also quickly judge, but after hundreds of thousands of repairs, from the circuit fault phenomenon, mechanical sound, plus the usual experience, can judge seven or eight, but there is no 100% certainty, most maintenance personnel use the replacement method, that is, suspect which part has a problem, just replace that one (to **), can you do it? If so, I will teach you step by step how to replace and how to check.

If it is not energized, it can also be checked, find the same model of compressor, compare and measure its inductive impedance, capacitive reactance, resistance, wave resistance, wave interference and other seven or eight motor parameters and the insulation of the shell (it is difficult to distinguish the light resistance), to measure about ten times at different temperatures, to put it in the constant temperature oil tank, each time half an hour apart, from room temperature to 150 degrees, etc., so that you can detect 100% of the quality of the compressor motor, the detection of the mechanical part is more complicated, can the above be done?

Use the refrigerant meter to connect to the high-pressure pipe of the compressor and press it with a vacuum pump If the watch hand is very fast, it means that your compressor is very powerful, on the contrary, the watch hand is slow, it means that there is no force, and it is not very cool, so you don't need to say so troublesome downstairs.

When the air conditioner is turned on, the air conditioner can run normally but the refrigeration effect is not good, either the lack of fluorine or the compressor is broken, if the noise and vibration are found to be significantly greater than usual in the operation of the air conditioner, you can judge that the air conditioner compressor is damaged, and the compressor surface becomes hot and the compressor cannot be restarted, indicating that the compressor is short-circuited. Solution: 1. The compressor does not work after power-on, and the protector works, usually the locking shaft or cylinder failure caused by compressor oil leakage or foreign body intrusion.

2. If the suction and exhaust valves of the compressor are damaged, and the system is not refrigerated or the refrigeration effect is poor, it is usually a failure that the suction and exhaust valves of the air-conditioning compressor are not seriously closed. 3. Collision between pipelines and casings, loose fixing bolts of compressors, falling off of hydraulic buffers, etc., such problems often occur in maintenance work, and generally have little impact on refrigeration performance. 4. The open circuit or working temperature point becomes smaller, this problem is easy to be confused with the micro-short circuit between the windings, but the working current when the thermal protector is damaged, and the current when the winding is short-circuited is larger, which is usually the damage fault of the thermal protector of the air conditioning compressor.

5. When the circuit is broken, the power supply is normal, the compressor does not work, once it touches the short circuit or the shell, it will energize to start the protector or burn the fuse, usually the fault of the short circuit, open circuit, coil contact with the shell grounding of the air conditioning compressor, so it is not easy to judge, please judge according to the measured current.

Hello Kiss Compressor is one of the most important components of a refrigeration system, and if it breaks, the entire refrigeration system will fail. Here are a few ways to tell if the compressor is broken: 1

Worse refrigeration: If you notice that your fridge or air conditioner is getting worse refrigeration, it may be because of a problem with the compressor. 2.

Louder noise: If the compression stool cleaner is faulty, it may make an unusual noise. These noises may be a low hum, a shrill rattle, or a high-pitched squeak.

3.Frequent repairs: If you find that your refrigeration equipment needs frequent repairs, it may be because of a problem with the compressor.

If you don't deal with it in a timely manner, the problem can become more serious. 4.Calorie excess:

If you notice that the surface of your refrigeration unit feels unusually hot, it may be because of a problem with the compressor. This issue can cause the device to overheat and can cause a disaster. 5.

Fluorine leakage: If you notice that your refrigerator or air conditioner needs to be refrigerant added frequently, it may be because of a problem with the compressor. This problem can lead to fluorine leakage in the refrigeration system.

In short, if you find any of the above situations in your refrigeration equipment, it is recommended to contact a professional maintenance personnel as soon as possible for inspection and repair.

Nowadays, summer is getting hotter and hotter, and air conditioning has become an indispensable comfort in people's lives, but what if there is a problem with air conditioning? Many people don't know how to tell if the air conditioner compressor is broken, so let's tell you a few suggestions.

First, listen to the sound. When you turn on the air conditioner, if you hear a screeching noise or a screeching sound, then it is possible that the air conditioner is broken. This is because the squeak and noise of the compressor is usually caused by problems such as insufficient oil supply, damaged bearings or wear of mechanical components.

Second, measure the temperature. If your air conditioner doesn't cool at all or doesn't cool well, then it's possible that the compressor is broken. At this time, you can use a thermometer to measure the temperature difference between the inside and outside of the machine, if the difference is not obvious or the temperature is too high, then you need to find a professional to overhaul it.

Third, observe whether the compressor is running. When you turn on the air conditioner, if the compressor in the outdoor unit does not run or keeps turning on, then it may be because the compressor is malfunctioning. Therefore, it is best to get a professional to have it checked at this time to avoid greater damage and repair costs in the future.

In short, the above three points are the basic methods to judge the failure of the air conditioner compressor, if you find the above problems, please find professionals in time to check and repair, to avoid greater damage and repair costs in the future. At the same time, regular cleaning and maintenance of the air conditioner during daily use can effectively extend the life of the air conditioner and ensure the stable operation of the air conditioner.

1. To judge the quality of the air conditioning compressor, we must first learn to identify the three binding posts on the air conditioning compressor, which are S, R, and type C, where S is the starting winding, R is the running winding group, and C is the common end.

2. Then use a multimeter to measure its resistance value, where the resistance between SC and RC is equal to the resistance between RS, which is the normal data. For example, if the resistance between RC is 5 ohms and the resistance between SC is in Euros, then the resistance between RS is in Euros.

3. If the resistance is offset too much, or there is no resistance between the three, then the compressor is likely to be bad.

4. However, sometimes, even if the multimeter measurement display value is normal, if the compressor is short-circuited, the multimeter cannot be measured.

5. For this situation, the easiest way is to use a multimeter to measure the power-on situation. If it shows that it is powering on, but the compressor does not start, you can change a starting capacitor (50uF) to try. If the compressor does not start after changing the capacitor, it is undoubtedly the compressor that is broken.

Summary. Hello, glad to answer for you. Determine whether the air conditioner compressor is damaged.

1. When the air conditioner is turned on, the air conditioner can operate normally, but the refrigeration effect is poor, indicating that the compressor is broken.

2. If the noise and vibration are obviously louder than usual when the air conditioner is running, it can be judged that the air conditioner compressor is damaged.

3. After running for a while, it will be found that the surface of the compressor is hot, and the compressor cannot be started again, indicating that the compressor has a short circuit.

Does anyone know how to tell if an air conditioner compressor is broken.

Hello, glad to answer for you. Judge whether the air conditioner compressor is damaged 1. When the air conditioner is turned on, the air conditioner can operate normally, but the refrigeration effect is poor, indicating that the compressor is broken. 2. If the noise and vibration are obviously louder than usual when the air conditioner is running, it can be judged that the air conditioner compressor is damaged.

3. After running for a while, it will be found that the surface of the compressor is hot, and the compressor cannot be started again, indicating that the compressor has a short circuit.

As soon as you open it, it turns it off.

As soon as it is turned on, it will be turned off, it may be that the actual indoor temperature has reached the set temperature, and the air conditioner does not need to work, and it will automatically enter the standby state; When there is a certain error between the indoor temperature and the temperature set by the air conditioner, the air conditioner will automatically turn on and run.

Hello dear, the way to tell if the compressor is broken is as follows.

1. Use a universal meter to measure the resistance value

There are three binding posts on the compressor, which are S, R, and C, which refer to the starting winding, the running winding, and the common end. In general, the resistance between SC and RC is the resistance between RS, allowing for small deviations.

If the difference is large, the compressor may be broken.

Second, the use of a universal meter to measure the power-on situation

Sometimes, the measured resistance is normal, but if it is a short circuit inside the compressor, it cannot be measured.

If it shows that it is powered on, but the compressor does not start, replace the starting capacitor, and it still does not start, then the compressor is broken.

Improper wiring at the terminal of the compressor, leakage of refrigerant in the system, damage to the capacitor, inconsistency between the capacitor specification and the compressor, unreasonable wiring of the power cord, copper plating or rust of the compressor, abnormal wear of the compressor, etc., will cause problems in the compressor.
