When you are saying it is noisy, then I will recommend to call a technician. Don't try to run it again. It may damage the scroll.

There is one valve to cut the air supply for machine.
Open this cover and close the valve.
Check motor belt is ok or not.
Check pump is inhaling air from filter side or not.

Check the drive belt also the motor pulley -- is it correctly positioned ??

Disassemble the two drive belts and then power the motor tt alone; if it does not turn or there is a problem with starting the control contactor, it needs to be replaced (you may find a lack of phase due to damage to the contactor). Disassemble the compressor element and see if there is a blockage at the bearings
