Why is my samsung refrigerator flashing 34 on temp display and not cooling properly

mine did the same thing. It was the mother board.

and guess what? they don't sell that motherboard anymore.

I will never buy Samsung again!

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 !?

it sounds like the refrigerator evap is frozen up causing the compartment to get too hot. shut the unit off and let it thaw out. then take the screws out of the cover to check the stryrofoam on the back side of the cover to see if theres broken spots on it causing the air to bypass the evap causing it to freeze. Theres two screws behind the light cover and two at the very bottom of the cover and two behind the decorative plugs about 1/2 way

I was having the same problem but with the refrigerator side. I know your problem was with the freezer side but I hope this works in your situation too. I was also told to unplug the fridge for 20 minutes and that did not do a thing to reset the circuit board in my situation. Unplug the refrigerator first. In the back of the refrigerator at the bottom is a metal panel. Remove that panel and off to the right side of it should be a white looking plastic box. Unscrew that box from the fridge and open it up to get to the circuit board. Remove ALL harnesses from the circuit board and capacitor. After doing so plug them all back in and reassemble everything back together and plug in the fridge. This should reset the board and allow it to function correctly. This is advice I got from someone else and everything as of today is cooling down like it should. I hope this helps everyone else out. Best of luck.

Also since the evaporator was frozen solid at the bottom on the refrigerator side I had to leave the power off until it thawed and then had to soak up all the water that collected at the bottom of it.

Hi Adshegern,

I think you have a fan problem. Your refrigerator mus have a bad fan or not working fan. I suggest you full out the refrigerator and open back lower cover. Two months ago, I have a problem like your. I fixed by replace a fan. You have to options to fix it.

Option 1. Check your refrigerator's fan with voltage. It think it should be 120VAC. If yes, you can buy a fan from electronics store (it cost about $12.00 to $17.00). they you remove the old fan and its motor out. Install the new fan in. Then you need to drill 4 holes to tie the fan. By doing this, you keep the fan running stable. The fan won't vibrate.

Option 2. You can go online to this website partstore.com and buy an exactly the one you need and replace the old one. It cost about $40.00.

Good luck
