I have a Samsung RFG297AARS Refrigerator. French doors on top, Freezer on the bottom The hinge on the left door that swings to seal the two doors is not moving when shutting the door to the frig. The plastic guide is low and misses the center mounted channel that should turn it to seal. Is there some kind of adjustment that I can make to have it swing shut?

A good place to view exploded parts diagrams is Sears Parts. See http://www.searspartsdirect.com/samsung-refrigerator-parts/model-RFG297AARSXAA0000/1482/0161000.html. Note that the parts you are looking for could be in the left door diagram or mor likely the cabinet diagram.

Freezer /fridge water/ice in fridge and or freezer

Usually due to CONDENSATION due to bad door seals or a plugged evaporator drain line? Can use a soft flexable tubing and very hot water to clean it out. Bad door seals usually need replacement, but u can use a blow dryer and something to pry it closer to the door wall while blowing hot air on to it. To create a seal, to test for bad door seals place a dollar bill in between the door and wall of fridge where it closes. Then slide out the dollar bill with door closed. It should offer some resistance and not be easy to pull out.
Most all fridges have a drain. Look inside your fridge for a "V" shaped channel with a small hole. This hole leads to a tube and a small pan which sits on top of your refrigerator's compressor. The defrost cycle causes water to run into the channel, down the tube, and then it generally evaporates with the heat of the hot condenser/compressor.
However, if that tube is clogged with food crumbs, particles , debris etc, you will have to clear it to get back to a normal mode of operation. A toothpick, pipecleaner, straw or a cotton bud can often do the trick.
Even a frost free freezer will still ice up at times in the areas away from the heated defrost area and the drain line can freeze. This icing causes the pipe work to the compressor to ice over or sweat and cause a puddle. Or if the drainage has frozen over, it will need to be de-iced. ( usually the line is under the freezer bottom plate covering. Towards the back of the unit) And there is another inside the fridge area also.
Give the freezer a good overnight defrost until it's totally clear of ice in addition to making sure the drain is clear to the pan at the back and then restart the freezer.

What do you mean by "pops"? If your problem is the door, then it is possibly leaking out your cold air. It could be the seal or the hinge.

My Samsung French door fridge #RF267abbp makes a knocking sound coming from the ice maker. The knocking lasts for about45 minutes and continues throughout the day and night, It is very annoying especially at 3 am.

tigthen and alligned the door screws together the shelves place it or arrange it possible of wiggle. then observe after.

It appears that your door hinges are loose. Open each door, take a close look at hinges at the top and bottom. You may be able to see an outline of where the hinge was and needs to be. Raise / Lower Door by hand until hinge is back in place, and tighten with a screwdriver. Pretty common.

Check the lower hinge of that door for a broken closer cam. The upper hinge is adjustable and adjusting the corners in the front will shift the cabinet to align the door also.
