First step.. did you run diagnostics? This is always step one when working on Samsung fridges. Samsung fridges will clear certain diagnostic code for 4-6 hours after unit is unplugged. If you don't use diagnostics prior to unplugging, you have to wait 4-6 hours for any codes to reappear.

did you replace all temp sensors including ambient sensor?

Make sure you don't have a stuck power cool button.

Should be able to engage a self diagnostic mode by simultaneously pressing Power Freeze and Power Cool buttons.  Take note of any blinking led segments particularly on the refrigerator temperature display.

Energy Saver - Lighing for 8 to 12 seconds for diagnostic (no Power freeze Power cool on this one). I always run Diagnostics on any electronic unit prior to and after performing any repairs.

Here's the Fast Track Manual which is all you should need for the proper diagnostics. Please post your results of all of the proper tests.

hello, the diag had us replace the compartment temp sensor lower center of fridge. and that's when we started to get cool air before we could not get below 70 degrees f then we we're told by samsung to reverse the stepper valve. Now we have got 22 degrees, no current temp display just set temp. no codes 88. 88 is all I get. the main board, 2 temp sensors the defrost coil have all been replaced.

I think you may have misunderstood the tech line. If you had no cool in the fresh food section but did in the freezer you could reverse the stepping valve (hot gas solenoid stepping motor switching valve) and you would see the ff section start to cool and the freezer warm up. But, you're really throwing the control for a loop, trying to cool one section and can't. I have seen many techs misdiagnose these units that with two sealed systems that share the same refrigerant and compressor. The little valves are tricky sometimes. You shouldn't need to do a sealed system repair just the electrical part on top if its changeable by itself.

Why would the hot gas solenoid stepping motor switching valve have any effect on the display of set and current temp?

I wouldn't put too much thought into the display showing the set temp versus the actual temp. The unit may only show the set temp and not the actual. That's always better that way the customer doesn't get worried about the temperature swings that occur with the air temperature.
