Samsung RF 4287 hars/XAA Freezer at 60 degrees only. Frij and deli box ok.

[Dennis Bran]

Samsung RF 4287 HARS freezer is on the blink.  Cannot get it below 60 degrees.  Switched out the freezer ceiling sensor as well as the evaporator defrost sensor, NO Change.

The icemaker is cool but not producing ice.  Also not sufficiently cold for freezing.  I think the ice maker and the freezer are connected someway but not positive.

Forced mode (FF1) overnight also no change,  Refrigerator and middle deli drawer has no problems.  Diagnostic mode shows NO faults.  This model has NO Diverter valve in the compressor compartment and I don't know if it is accessible. 

Have NOT checked the Fresh Food Refrigerator compartment evaporator as I am under the impression it is not associated with the freezer problem and it is providing proper temps.  Two fans  in freezer working as I can feel cool air being blown out.

Hoping someone can provide info.  Saw HAPPYDAD post over 6 years old with same symptoms but his post ended with no solution.  At a loss and about to call a tech in but at $100 just to enter the house, I don't know if its worth it if it is unrepairable.
