NOT DEFROSTING IN FRIDGE SECTION EVAPORATER COIL / ERROR CAME UP AFTER UNPLUGGING UNIT 86/88 IS THE CODE , STRO

I have also found the tech sheet on a similar unit. Unfortunately it does not list the error codes.

Thank you for your question.Based on your model number this is actually a Samsung built refrigerator.I have attached a link to a Samsung refrigerator with your issue and you will find it to be the same unit as yours.Good luck.
