Why is my AC compressor not receiving power?
There are many ways for AC compressor clutches to receive power. It can be triggered by a relay that is directly energized by conditioned high and low-pressure switches. Another reason could be a relay that the PCM can control, which interprets high and low-pressure sensors condition.
What causes a compressor clutch to not engage?
There are three reasons why the compressor clutch does not engage, especially if the sensor detects them. These include low or excess refrigerant and insufficient oil. Burnt fuse
How can you tell if your compressor has overcharged refrigerant?
Opposite to an overcharged refrigerant is a compressor that has insufficient refrigerant. Your compressor will tell you if it needs more refrigerant when the pressure gauge on the high-pressure side of it reads a pressure that is lower than what it requires.
It could be because of a blown fuse, a bad clutch coil, or an open on the wire to the clutch coil. It could also be of poor ground or a low-pressure lockout.

What to do if your car compressor is not working?
Turn the key to the RUN position and turn the blower fan to HI. Turn the AC to MAX to start the radiator fans. Then start adding refrigerant. If your vehicle is an orifice tube system, the refrigerant gas will flow through one of the open compressor reed valves and into the condenser coil.
What causes an AC compressor to not engage?
If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.

Why is the clutch not engaged on my gas compressor?
But if the system is low on refrigerant, the clutch will never engage. Some DIYers then hotwire the low pressure switch to force the compressor clutch to engage while they recharge. BAD MOVE. At that point you’re running the compressor with little to no oil.
What happens to the clutch when the AC is turned off?
The clutch becomes energized when the ac is turned on. The compressor belt and the armature plate of the compressor drive are engaged, which causes the compressor drive to rotate along with the engine. When the ac is turned off, the clutch is de-energized and the compressor belt and the armature plate of the compressor drive are disengaged.
