Customer Questions and Answers for Evaporator Assembly by Samsung

Hello Lena, You will need to thaw the unit out so the refrigerator evaporator fan cover assembly can be removed without breaking the styrofoam backing. If the styrofoam backing gets broken, it DA97-11772B will have to be replaced to prevent a frosting issue from occurring again. When removed, first move the sensor on the copper Freon line at the top of the evaporator coils to the other Freon line. You will then need to clear the ice from the defrost drain and install a defrost drain heater 819043. This should take care of the issue.
