Can Car AC Compressors Repair?

In general, the cost of replacing a new air conditioner compressor is expensive. If it's just some basic problem like the poor condenser, damaged gasket, etc., it can be repaired. We recommended direct replacement if the coil would burn out, short circuit, or has other serious conditions due to some reasons.

Because in complicated cases, A/C compressor replacement cost is relatively higher, and it is easier to directly replace it with a new one. The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit. The air conditioner compressor is generally installed in the outdoor unit. The refrigerant is extracted from the low-pressure area, compressed, and then sent to the high-pressure area for cooling and condensation. The heat is released into the air through the heat sink. The refrigerant also changes from gaseous to liquid, and the pressure increases.

Signs of a bad car ac compressor

In daily use, if there is a problem with the air conditioning pressure reducer, there are usually obvious characteristics:

1. Although the air conditioner is on, there is no obvious temperature change. In this case, it is generally necessary to check whether the refrigerant of the air conditioner is used up, and then check whether the suction and exhaust valves of the air conditioner compressor are not closed tightly. If there are no above two conditions, it means that the air conditioner compressor is in the initial stage of damage.

2. loud noise. After turning on the air conditioner, there is a louder noise than usual, and there is even an obvious sound of metal friction

3. The opening or operating temperature point becomes smaller. Usually, the air conditioner compressor is short-circuited, or open-circuited, and the winding touches the ground fault of the chassis, so it is not easy to judge. It should be judged according to the measured current. This problem is often easily confused with a slight short circuit between the turns of the winding. The difference is that the working current is normal when the thermal protector is damaged, and the current is too large when the winding is short-circuited. It is a fault of the air conditioner compressor thermal protector. When the circuit is broken, the power supply is normal, the compressor does not work, and the protector acts or burns the fuse after the power is turned on when the circuit is short-circuited and the case is touched.

What causes car ac compressor failure?

The equipment itself is aging or damaged: 1. Burning out of the motor coil. 2. Poor heat dissipation of the condenser. 3. Leakage of the exhaust valve. 4. Damage to the insulation layer of the stator winding and open circuit.

User habits or long-term use: 1. The dust accumulated in the condenser cannot be discharged for a long time. 2. The air cooler pipeline is blocked. 3. There are pollutants in the system, including air, moisture, dirt, debris, leaves, soot, acid or insects, etc. 4. Every air conditioner compressor types require regular maintenance. If the daily maintenance is insufficient, the engine oil or lubricating oil will not be enough, resulting in equipment loss.

Replacing car ac compressor

If your equipment only has some small problems, such as the blockage of equipment pollutants and the damage of individual parts, you will purchase the corresponding parts for replacement. If it is a circuit problem, a problem with the refrigeration system, etc., we recommend that you replace it in time, because all parts of construction machinery are a whole, and each part has something in common. If you do not replace the damaged compressor for a long time, it may cause irreversible damage to your air conditioning system, vehicle engine, and other important components, and the loss outweighs the gain.
