Causes of Car AC Compressor Clutch Failure

The compressor clutch of your vehicle’s ac is among the most crucial parts of the A/C system. The compressor is responsible for pressurizing the entire air conditioning system, pushing the cool refrigerated air throughout, and ensuring that things are working efficiently. 

However, as the ac compressor clutch is cycling on and off consistently, it begins to show signs of wear after some time. When something happens to the compressor clutch, your vehicle’s A/C will not be able to continue blowing cool air. A worn, failing, or damaged clutch will be unable to control the refrigerant’s flow in the system and blow cool air.

 

Too Little Refrigerant

When the pipes for refrigerant develop cracks or holes, the refrigerant will leak out. After some time, there would be too little refrigerant left, and the compressor will seize. It is because it will need to work extra hard to pump insufficient refrigerant through the system. Eventually, it will break, and you will have to shop around for air conditioning auto parts.

Excessive Amount of Refrigerant

It happens when an inexperienced mechanic or technician works on your car’s A/C system and unintentionally adds either a large amount of refrigerant or the wrong refrigerant. 

The size of the Suction Line does not match

When the suction line is either too big or too little for the ac system in your car, it can cause the ac compressor clutch to fail.

Filthy Coils

Regular use of car air conditioner will cause grime build up on the condenser coil. When the grime becomes too much or has been there too long, your vehicle’s ac system will not be able to eject heat from the system. The condenser then runs constantly to cool your vehicle’s interior. Owing to the pressure and temperature increase, the ac compressor clutch will overheat and may fail.

Electrical Issues

Electrical failure happens at times. It can cause acid build-up, which can damage the compressor and other parts. When you approach a technician or mechanic due to a failed compressor, they will look for corrosives. If there is an electrical burnout, and the entire system is damaged, it will need replacing air conditioning auto parts.

The compressor clutch is a vital part of your car’s air cooling system. If your ac system is not cooling efficiently, see a qualified technician immediately.
