* Low refrigerant level: If the refrigerant level is too low, the compressor will not be able to create enough pressure to circulate the refrigerant and cool the air.
* Faulty compressor clutch: The compressor clutch engages and disengages the compressor. If the clutch is faulty, it will not be able to engage the compressor, even if the refrigerant level is correct.
* Electrical problems: A variety of electrical problems can prevent the compressor from engaging, such as a faulty wiring, a blown fuse, or a bad relay.
* Faulty pressure switch: The pressure switch turns the compressor on and off based on the refrigerant pressure. If the pressure switch is faulty, it may not turn on the compressor, even if the refrigerant level is correct.
Solution:
The solution to this problem will depend on the cause. If the refrigerant level is low, you will need to add refrigerant. If the compressor clutch is faulty, you will need to replace it. If there are electrical problems, you will need to find and fix those problems. If the pressure switch is faulty, you will need to replace it.
Conclusion:
If your AC compressor is not engaging, even with full freon, you will need to diagnose the problem and make the necessary repairs.
