Northland freezer model # UF30K-1485 Serial # 01K866398.
Worked on a Northland freezer yesterday, and when I got there unit was holding about 20 degrees F. Usually pulls down to about -10 F. This a reach in freezer on R-404a. Compressor was extremely hot to the touch, condenser fan running,fan shrourd intact and condenser was clean. Checked evaporator for ice build. Didn't have any tap valves with me so I couldn't check for restriction or low charge. Going back this morning to tap on to sealed system. Any ideas.
