Have had ours for 18 months or so, and works flawlessly for us.

If still under warranty, call Samsung and ask they want you to work with to get this resolved.

That being said. To get our unit in the coach, the doors came off. Have you done the old dollar in the seal test to see that you have solid contact with your door gaskets?

Please let us know how this turns out, and what you find out. As it could help others down the road!

Best of luck to you,

I have a 4+ year old Samsung RF-197. I have the fridge is set at 38F, freezer is set at -2F.

My fridge fluctuates between 36F - 39F everyday. The freezer used to fluctuate between -5F - +0F everyday for the first coupe of years. However, for the past two years of more the freezer is now fluctuating between -8F - +16F. This swing happens a few times throughout the day and night.

I have run a diagnostics on the fridge but it always comes back with everything checking out OK.

I've was told by a RV service technician from Elite RV in Harrisburg Oregon where I had stopped for some work back in 2015 that it needs a new control board.

I haven't taken the time to order a new board as that swing in temperature has not affected the quality of the frozen food. Plus it spends more time below 0F than above 0F.

It's possible that your control board has gone haywire.

I can't remember all the details, but if you take the back panel out (on the inside of the refer), there was a drain line in there that was getting plugged up and causing issues.

Thanks for suggestions..Smitty, not sure how to gage dollar bill test...yes some resistance when pull on bill but not much..Can't say tight enough..
Dr4, your problems with freezer similar to mine except 42 degrees grow bacteria.
Going without saying our problems with fridge go beyond just simple replacement..
Would love to fix it with circuit board, new door seals etc vs replacing..Samsung says they want me happy...hope my installer feels same way..

Sorry for your troubles. This doesn't sound right. Our's is always right on the mark, 34 & 0 degrees. Even after a long travel day running off our OEM MSW inverter.
