What fluctuating are you getting,the unit normally uses r404a,the condensor fan is pressure controlled so it will not run until delivery pressure reaches 250 ish then it stops at approximately 170,are you getting any codes on the display panel? If you hold the set button it will show past alarms which will be for example PO1'PO2 etc
