Question about Refrigerators
The freezer is not cooling. first we cleaned out the back coils. then found that there was ice buildup showing through the holes in the back of the freezer. so we defrosted that. now it is cold enough to barely keep the food frozen and the temperature on the digital readout on the door says 2 degrees but we put a thermometer in the freezer and it reads 20 degrees. fan is running and compressor is warm. what are we missing?? does the digital control panel have anything to do with it? thank you for your help. carol
If the ice buildup was by the pipe just going into the evaporator in the freezer compartment and the suction line going into the compressor is warm to the touch and not cold and/or sweating you are low on freon.
If the entire evaporator was buried in ice, the ice covering is also serving as an insulator and preventing internal temps from going down any further. There is a problem with the self defrosting mechanism which is designed to prevent the ice buildup. Could be either the defrost timer, defrost thermostat or the defrost heating element. Hope that it is just the heater element. If you have an electronic module for the rest you are in for unpleasant surprise to replace the unit. Proprietary parts mucho expensive plus labor.
Until you fix it, just let the unit manually defrost (U can use a hair dryer to speed it up) and turn it back on again. It will work fine till the ice builds back up. Keep opening and closing of freezer compartment to minimum to minimize moisture laden air that enters compartment.

When you have an ice problem on the evaporator coils, the problem is usually the defrost timer is bad. On this unit, the timer is located on the main control board. http://www.repairclinic.com/Samsung-Refrigerator-Model-RB195BSBB-ID-1067877-Circuit-Board-Timer-Parts

it can be two things the refrgerator probably has a small refrigerant leak therefore it ices up, or the defrosting heater on the begining of the coil is faulty.
