Hi @kmm56489

Your refrigerator is basically a rebadged Samsung model, as it uses all Samsung parts.

Couple of things to check first, assuming that the sealed system high and suction pressures were tested as being OK, after the new evaporator units were installed and the correct amount of refrigerant had been pumped back into the system.

i.) Check if the freezer door seals are OK. Place a turned on flashlight inside the freezer compartment and with the door closed normally i.e. no pressure on it by you to keep it closed, check if you can see any light coming out past the freezer door seal at all. Check all around the door. Perhaps this is best done at night when it is dark.

ii.) Check if the freezer ice door is closing properly, preventing warmer air getting back into the freezer compartment. Here's a video that may help. Note: The part number shown in the video i.e. DA97-00883E is for the one used in your model.

If the above are OK, I couldn't find a service manual online for the model, but here's the service manual of an equivalent Samsung series model that may help to find out what's wrong.

Go to p.33 in the manual (p.34 of 78 pdf) and run the Self-diagnostic function during normal operation procedure as described and check if any error codes are shown.

The error codes and their possible causes and checks are shown on the following pages.

If you find the problem and a part needs replacing, here's the parts list that is useful.

Locate the wanted part in the list and note the manufacturer's part number, that is listed with it. Search online for the part number only, to find suppliers that suit you best.
