Found the Walk-In Cooler unit above 50 degrees Fahrenheit with the compressor running. Went on top and found the unit was low on refrigerant. The condenser fan shroud is missing and the door closer does not work. Leak tested and found the evaporator coil leaking. Added R404A to a little bit over a full sight-glass. Brushed off condenser coil. Need to quote . Norlake does not identify parts after hours. Need to call on Monday.
