bobcat E 60, air condition system clicking and turning the clutch on and off

[Bobcat todd]

I’m working on an E 60 with an AGSZ serial number, it’s a Doosan older excavator. The left-hand air condition display works and is in good shape but when you click on the green button to make the air condition work, it cuts the clutch on the compressor on and off and there’s a steady, audible tone. That’s irritating as hell. Can’t figure out why this is doing what it’s doing

low freon can cause this

Loose/worn connector or wires on a sensor maybe?
