Samsung fridge freezer SR2028CVW not cooling or freezing

SOURCE: Digital display is blank in GE Profile fridge

Hi. Its either a bad motherboard or control board. I would check the control board for any obvious signs of damage to the board first. I've seen the control board go blank on the GE side by side and it turned out to be the motherboard. The motherboard is located behind a cover on the back of your refrigerator cabinet. You should have a new motherboard on hand at all times because they fail alot. Be sure to put a surge protector on your refrigerator. Good Luck, Mack

soiunds like the coil on the refrigerator side is iced up.take and open the refrfigerator side and take a blow drier and after removing the 11 screws use the hair drier to slowly melt the icec behind the cover. If you pull too hard and or too soon you'll break the stryofoam ductin that has to be around the coil. then make sure that the drain line is clear reassemble and have a Merry Christmas!

I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........

In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.

Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.

Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)

Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.

My husband removed the covers inside the fridge which contain the lights and the cooling fan. The problem was the icing up of the cooling fan (which circulates the cold air) preventing it from rotating also the drain hole at the bottom of the fan was also iced up.
The fridge was switched off at the wall socket whilst working on it. After removing the panel containing the fan and unplugging the connection take the panel outside. A hair dryer was used to thaw out the ice. The drain hole was made slightly bigger to hopefully prevent this happening again.
When panel is screwed back in fridge make sure the black sealing tape is in position also take care not to damage cooling pipes which are attached to the evaporator unit. Defrosting a couple of times a year might prevent this happening again. It seems to be a design problem which im sure the makers will be aware of and modify future appliances. Q Will the makers repair this problem free of charge even if the warranty has expired !?

Ok, what I found out is that there are codes built into the front panel. If you hold the top left and right buttons for 5 seconds, the fridge will reset. If there are no issues, the panel goes blank. If there is a dash in the right side of the panel, there is an issue with the fridge side. In the left, freezer side. The dash indicates a defrost problem. Only a couple of things can cause this. 1. Sensor 2. Heater 3. Fan, 4. control board.
