Orman, we had the same problem. I found this DIY site online http://imgur.com/gallery/otSiW
It worked and haven't had issues since. 

Joel Ashley:
Our home GE I discovered was Samsung built, and this spring developed water pooling under the deli drawer that's under the crisper drawers.  The pool would then freeze and stick to the drawer bottom and the deli drawer wouldn't open. 

Online I found several approaches to the same fix the previous poster mentioned... replacing or augmenting the metal strip in the evaporator's drain port thats supposed to keep it too warm to freeze and plug up.  When the drain freezes the water overflows, runs down inside the wall and to the floor under the drawers. Using the original as a pattern I made my own simple strip out of aluminum sheeting, but with a longer "tail" that goes down into the port further than the factory one, and with fingers that wrap thoroughly around the heater tube.  It's worked fine since, so the fix does prevent the drain tube from freezing closed.  There was a small amount of gunk that I flushed out of the drain tube, so ice isn't the only possible plugging culprit.

Of course your leak could be from an entirely different source, but this one apparently has been a common malady with Samsung-built units.

Seems legit... A malady with the salady..drawer.   ;D

After removing the "snap in" panel on the inside back of the fridge, exposing the evaporator, I poured hot water in the drain port.  This took a very long time since the port doesn't hold much, so you have to do it with an unplugged, unloaded fridge. I put the food in ice chests with ice bags, etc.  A person that's full timing would need to do the following before inserting a modified drip tube port heater strip, but otherwise you could wait to fix the strip after the Coach was in storage and the tube's ice plug had melted on its own.

You have to put towels around the drain port/funnel under the evaporator to catch and wipe overflow, and sop out cooled water from each previous application, then add hot water every 5-10 minutes until it eventually melts through the ice plug that's way down into the drain tube.  As I recall, a turkey baster is handy for squirting in hot water and sucking out cooled water.  When it finally gives and clears, you go may need to empty the drip tray under the back of the fridge. 

Getting the back panel to align and press back in place evenly was tricky too.  There are videos on YouTube that helped me.  This may assist getting you started as well:   https://www.searspartsdirect.com/article/how-to-get-rid-of-refrigerator-puddles.html

Don't try a hairdryer as it can easily warp plastic panels and mess up their fit and seal.

We just had a defrost issue fixed at an in home installation and asked the installer about Samsung fridges for motorhome installation. Almost every fridge made has a "duckbill" rubber valve draining the defrost water from the freezer to the drainpan where it is supposed to evaporate. After a few years they all glue themselves shut as the rubber deteriorates and the water doesn't drain properly, it ends up in the bottom of the freezer as a sheet of ice, which then overflows onto the floor. They all require replacement. The reason for the valve is so moisture doesn't flow from the outside in humid weather to the inside of the fridge creating a hyper-frost condition. The manufacturers found that this valve wasn't necessary and caused too many warranty repairs and they discontinued the valve. Samsung is apparently one of those that did not. The hot ticket is to remove the valve BEFORE INSTALLATION so you avoid this problem. He also disliked the lack of support he got from Samsung on warranty repair, being left twisting in the wind with only a Samsung shrug in response. He recommended Whirlpool, also with the removal of the said valve before installation. YMMV. I'm looking for the Whirlpool equivalent of an RF 18 to replace our old fridge.
