Samsung RS2533SW freezer not cooling problem

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.

I also had an issue with the freezer not cooling. I found that one of the kids had left the freezer open a crack overnight, and the humidity caused ice to form on the coils. This stopped air flow and thus cooling the unit. I had to take the back panel off (on the inside of the freezer) and use a hair dryer to thaw everything out.

We did what schin7524 suggested and it worked like a charm!! Saved us on a repair man and/or a new frig. Learned a lesson to pull frig out once a year and clean the back.
