What happens when the AC compressor is not engaged?
If your air conditioning system is turned off, the clutch is not engaged, hence the AC compressor is not driving. Once you turned your air conditioning system on, the AC compressor will start rotating by engaging the clutch. This is the reason why you hear your engine makes louder noises after turning the A/C on.

What to do when your AC compressor doesn’t work?
If AC compressor clutch doesn’t engage automatically when turning on the AC switch in the car AC panel, you need to check the refrigerator and compressor oil levels. At the compressor’s front side, unplug the single wire connector, take a jumper wire and attach it to the wire that you just disconnected from the compressor.
How does an AC compressor get its power?
An AC clutch is what makes the AC compressor to turn. It is connected to the flywheel with an accessory belt, and that is how it gets its power. The AC clutch is controlled by a clutch system. The shaft is joined to the flywheel’s rotating shaft by an electromagnetic switch.
What happens when an AC compressor is not engaged?
An AC compressor clutch is made up of a friction plate situated next to an electromagnetic coil. Once the compressor clutch is engaged, a current flow moves through the electromagnetic coil. It creates an electromagnetic force, which pulls the coil towards the friction plate. This gives power to the pump rotor that keeps the compressor running.
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 if you run a compressor with no oil?
At that point you’re running the compressor with little to no oil. You may get it to accept a charge, but you may have already damaged the compressor before the system reaches full charge. NEVER try to bypass the low pressure switch. Doing so will force the compressor to run with inadequate oil and can destroy the compressor.
What does low side pressure on compressor mean?
Static low side pressure won’t give you any idea of system charge. You could have a low side target range of 50-psi and see that static pressure on your gauge. All that tells you is that there is some refrigerant in the system. But 1 ounce of refrigerant will provide a 50-psi reading the same as a full system.
