Hi @kdalla5 ,
Have you checked that the condenser coils are clean and not dusty etc? Dirty condenser coils reduce the efficiency of the cooling cycle making the compressor work harder trying to achieve the set temperature as the heat that the refrigerant absorbed from the freezer compartment is not dissipated to the air as quickly.
You said that you replaced the door seal but check that it is providing a good seal with the door jamb in case it is a door alignment (hinge?) problem allowing the cold air to escape (or warmer air to enter if you prefer). Place a piece of paper between the door and the door jamb and with the door closed try pulling it out. It will come out with a bit of effort but it shouldn’t be too loose or just fall out by itself. Try this at various places around the door, top, bottom and both sides.
If the compressor is running constantly trying to cool down the freezer compartment but it is not reaching the set temp it sounds as though there is a problem with the sealed system somewhere.
Check for any frost on the lines to the evaporator unit from the condenser coils or to the compressor which may indicate that there is a blockage in the system.
Also check for any oily residues on or below the compressor or on the condenser coils which may indicate a lack of refrigerant in the sealed system. There is a special oil mixed in with the refrigerant to lubricate the compressor and sometimes when there is a leak, the refrigerant will escape to the air undetected but the oil may leave a trace.
The only thing after this is to get the high and low (suction) pressures in the sealed system tested to see if they are OK or not. The pressures will tell what and where the problem is e.g. lack of refrigerant, blockage, faulty compressor etc. Depending on your location you may need a licensed refrigerator repairer to do this due to the environmental regulations regarding the handling of refrigerant gases. Besides which they have the necessary equipment to do the checks. Here’s a link to the wiring diagram for your refrigerator. It is useful as it not only shows the wiring, it also shows the pressures for the sealed system
