There is one small plastic cover which is hiding center screw, pop that off carefully and you will see it. Good luck, I have been having problem for a long time, mostly in summer, so I am just starting to pull it apart.

If you have french door RF266 version, there is a rack bracket mount in center of the plastic twin cool panel, and one screw is at top of rack, small square plastic cover same as the exposed one at the bottom of rack bracket.

I must warn you, cover is probably stuck if it was like mine with frost and ice buildup behind cover. Defrost with hair dryer first is best advice. Also, there are small raiser arrow indicators, two on each side, these are plastic grasps, so you have to apply a little screw driver pressure to release cover. If you get one side released, the other comes out easy with a little wiggling.

Good luck,

Yes, this is a constant issue, and it is always the same problem, ice frost buildup given the defrost cycle is too short ezpecially in summer months. I solved problem by blow drying ice, ran a coat hanger down drain hole at the center bottom drain hole as ice was formed down about an inch into drain. It was hard as ice, not just frost, and this has been the same issue over and over.

This time I wrapped 12 guage copper wire around bottom of defrosting heat coil and then inserted one end of copper wire down drain hole. Now when defrost cycle comes on, it heats the copper wire melting any build up at the drain hole. So far, so good, but easy fix overall.

The coil is metal, square in shape with input plug at top right hand side and surrounds to evaporator. Coil bottom is close to the drain hole where there is a metal shelf or gutter like in shape, the hole is in middle, so wrapping the wire around coil tightly is how wire picks up high heat from coil during defrost mode every 8 hours or so and this will keep the hole clear of ice preventing overflow into bottom of refrigerator section, or under veggie bin. I had this problem get worse in summer, not much of problem in winter months.

As to cracking sound, yes, they all do this, expansion noise, normal by what I heard from Samsung's useless service support system. I got fed up with waiting for a call back, and after weeks of emailing and leaving messages, this is when I decided to fix it myself. Icemaker is not the issue with water building up unless it was visibly leaking from spout. I did have this water line freeze up and stop working once or twice due to ice buildup in water unit at back left corner, so this is another issue common in these terrible units. Never again, my Samsung Plasma TV just blew too, so not happy with this Korean junk.

Good luck,

Wow, Genius! Is there any risk of fire in doing this? I went to home depot to pick up some copper wire and when I told them what I was trying to do with it the lady got upset and almost didn't want to sell it to me claiming someone has caught their fridge on fire and burned down their house trying to do this. I can't see how that could happen given that copper doesn't catch on fire. How hot do the coils get? Could it melt the plastic around the drain tube if it's in too deep?

For those having trouble locating the heating coil, this thread has clear pictures to help you find it http://www.justanswer.com/appli...freezer-french-door.html
