How does the AC compressor work?
Your car’s compressor is one of the key components of your car’s air conditioning system. The compressor’s job is to compress the refrigerant gas and pump it through the system so that it can remove heat and humidity from the air.
The compressor is usually very reliable, but if it fails before its expected life span (10 to 15 years), it is often due to an underlying cause that is preventable. If it does fail, it can be expensive or impossible to fix. By maintaining your car’s air conditioning system, you can help prevent compressor failure and keep your car cool in the summer months.
9 Reasons for AC compressor failure
When an AC compressor fails, it’s often the result of an underlying issue that has caused stress on the system. By addressing these underlying issues, you can help prevent AC compressor failure.
1. Dirty air filter
A dry air filter is one of the most common reasons for a car’s AC compressor failure. The filter keeps dirt and other particles out of the compressor, but if it’s dirty, it can cause the compressor to overheat. To prevent this, make sure to change your air filter regularly and keep it clean.
2. Low refrigerant level
If the refrigerant level in your car is low, it can cause the AC compressor to overheat. To prevent this, make sure to keep your car’s refrigerant level at the correct level.
3. Defective relay
A defective relay can cause the AC compressor to overheat. If you think your relay may be defective, have it checked by a mechanic.
4. Leaky hose
A leaky hose can also cause the AC compressor to overheat. If you think your hose may be leaking, have it checked by a mechanic.
5. Faulty fan motor
If the fan motor in your AC unit is faulty, it can cause the AC compressor to overheat. To prevent this, make sure to replace your fan motor if it’s faulty.
6. Faulty AC clutch
If the AC clutch in your car is faulty, it can cause the AC compressor to overheat. To prevent this, make sure to replace your AC clutch if it’s faulty.
7. Blocked condenser fins
The condenser fins on your car’s AC unit help dissipate heat and keep the unit cool. If they’re blocked or covered in dirt, they can cause the AC compressor to overheat. To prevent this, make sure to clean them regularly and keep them clear of debris.
8. Clogged expansion valve
The expansion valve helps regulate the flow of refrigerant in your car’s AC unit. If it’s clogged, it can cause the AC compressor to overheat. To prevent this, make sure to clean it regularly and keep it clear of debris.
9. Blown fuse or tripped breaker
One of the most common reasons for a car’s AC compressor to fail is an electrical issue. This can be caused by a problem with the power supply, the circuit that powers the system, or a break in the electrical connection. If you suspect that an electrical issue is to blame for your compressor failure, it’s best to take your car to a qualified mechanic for repair. With their knowledge and expertise, they’ll be able to pinpoint the root of the problem and get your AC up and running again in no time.
Those are the 9 top causes of car AC compressor failure. To prevent your compressor from failing, make sure to keep an eye on these potential problems and have them fixed as soon as possible. If your compressor does fail, don’t panic! These solutions will help you get it up and running again in no time.
