Hi,
I have problem with one commercial refrigerator with danfoss 120F0002 external compressor, before few days it was fully charged with 404A and oil and now it generate more cold air but also it generate too much noise and when is very hot outdoor it sometimes stop to work many times because pressure switch power it off!

Also when I check sight glass almost immediately after compressor start inside it look like mist, please check video:
