Cant get it down far enough...11 degree temp,low pressure is 24.5,hi pressure is 275 been running for 4 hrs straight. This is a True three door freezer,about 4 yrs old ,has 404a refrigerant
If the unit is indoors, the pressures are not that bad. I would look for possible issues with air flow. Maybe heavy frost forming on evap. If not, then go to basics. Remove charge, replace filter/dryer, pull good vacuum, weigh in the charge. This usually eliminates most problems.
