Raising the front of the fridge is not a solution. Doesn't hurt to do it, but it's not going to help, either.
I have a model RF28HFEDBSR. Bought in 2014. Started getting ice buildup on the evaporator coils about 6 months ago. I usually also get ice buildup forming in the ice maker compartment. When I first experienced the problem, I used the twist down legs to raise the front off the wheels. I also replaced my water filter. Those were the two solutions offered by Samsung. Neither has worked. I have now defrosted the fridge 3 times in 6 months.
I have observed water pooling under the crisper drawers. But that's the least of the problems. The big problem is that the ice buildup eventually gets so great that the ice maker stops working and the fridge starts to buzz because the fan in back of the fridge is striking the ice buildup.
Samsung knows this is a design flaw. They have issued a technical service bulletin to supposedly address it. They are also facing a class action lawsuit in the federal District of New Jersey. Samsung's motion to dismiss the suit should be heard in late May 2018. Assuming they lose (and I think they will), Samsung will likely settle quickly and perhaps everyone will finally get some relief. That relief will likely require a mandatory, free repair and perhaps a monetary pittance.
For now, best you can do is badger Samsung for a fix. The best Samsung initially offered to do was pay for material, but not labor. So they comp a few bucks in parts and hit me with hundreds in labor?! That's real generous, Samsung. Creeps. It took me 5 days of calling and speaking to over 10 reps, including several managers, but they finally relented and are paying for the entire cost of the "repair." You have to be persistent, and you have to speak to a manager. Don't let them admonish you that your fridge is out of warranty, or that the best they can do is pay for material. They KNOW this is a *design flaw* that is subject to a lawsuit.
Mind you, I have no idea if this repair will actually fix the problem, but it's a start.
This advice is pure nonsense, pardon me for saying so. This problem is a known issue with Samsung, even though they keep selling them. The cause is a piece of metal attached to the defrosting heater cableing behind the rear panl inside the fresh food compartment. The little piece of aluminum is attached to the heater and is supposed to stick down into the drain hold under the coils... it should transfer some heat from the heater into the hole to prevent an ice plug. Well, it barely sticks down 1/8" into the hole... Ice plugs it up, water can't drain, more fruost leads to a massive ice build-up which stops the fan, which warms the food compartment, which pools water (which often freezes) below the deli drawer, which stops the fridge from keeping food cold.
This is a KNOWN ISSUE and Samsung should refund... buyback... recall ALL units with this problem (there are many models).
In regards to the accepted solution: I'm assuming it should be defrosted first and then raised? Or will it defrost after raising? Can anyone verify that this works? After reading all about the multitudes of angry Samsung customers and the class action lawsuit I'm feeling a bit hopeless!
Raising the front does work! I have regretted buying my Samsung refrigerator right from the beginning. Not only has it made this terrible noise from only about 2 weeks of ownership, but it had a faulty compressor. Samsung did replace the compressor, but it took 7 visits from 2 different repair companies to convince them. After that, the noise was still so loud tha the appliance store (who also does repairs) took my fridge for an entire month and plugged it in at their repair shop. They said the stupid thing never made a peep while it was there...probably because they had it sitting properly. Basically, I've been suffering this poorly designed appliance since June 2016 for two reasons: 1. It's a crap design and 2. The guys who delivered the appliance didn't install it correctly. They had it sitting on its front wheels - never lowered the legs. Mind you, I had this fridge delivered twice from the appliance store and neither time did they bother to bring down the legs/lift the front off of its wheels.
This week it got so bad that the vibration was causing the top freezer drawer to rattle constantly and the fridge was running non-stop with the ice maker freezing over. So I found the advice to raise the front. I did that on Wednesday. I did not defrost the appliance and I really didn't raise the front very much...just took the wheels about 1/8 in. off the ground. The fridge was already level, just sitting on its wheels. I never did defrost the fridge, just let it defrost itself through regular cycling. It has not made a peep since Thursday!! This is the first time in 16 months that I can sit in my living room and enjoy peace.
So TL;DR - it works!
There is something very flawed with my Samsung french door fridge. I have been using an automatic power graphing monitor to track what is happening.
Back when my troubles began, it all started with the fan noise. That was from a large buildup of ice in the evaporator compartment that eventually grew into the path of the fan blades.
Why does this happen? The refrigerator ices up because the defrost system times out. The defrost system depends upon the defrost sensor to tell when the evaporator chamber has warmed up sufficiently, thus indicating that any ice has melted. Once the temperature threshold is reached, the defrost cycle ends.. If it does not detect a warm enough temperature after 1.5 hours, the defrost times out and will NEVER RUN AGAIN until you shut off the power to the fridge. That resets the error.
How do I know the defrost timed out? First, I can see from the power use graph a drop from 108 watts to near zero, followed by the compressor resuming and power use spiking back up. To verify, if I hold down the Fridge and Freezer touchpad buttons simultaneously for about 8 seconds (until all of the entries on the display light up and flash), then it flashes "25E" for a minute or so. That is the defrost error indicator. As far as I know, the only way to clear that is to remove power from the fridge. Then it can defrost until the next timeout.
Are my wheels off the floor? Yes
Is the defrost working? Yes, my monitor shows 108 watts being used during defrost. That is correct within measurement error. Furthermore, when I open the cover to expose the evaporator compartment, it is free of ice. And the gutter at the bottom has no collected water. The drain is working fine.
Is the sensor bad? I doubt it because I just installed a new one.
Is there anyone who can give me technical support? As far as I can tell, that sort of thing doesn't fit Samsung's belief system.
What is wrong? The last time I cycled through the Samsung "support" system, I was given a trouble ticket number and referred to the only official Samsung repair location in Seattle. They told me I could not talk with a technician over the phone unless I paid something like $80 for a service call. This is to talk with a technician!!!
I am very reluctant to spend money on a service call on a refrigerator that's had so many reports of refrigerator defrost problems. I am simply not convinced that the repair folks can fix this fridge.
Back at the beginning of the thread, there was a claim that all you need to do is tilt the fridge back. Bogus!
A REAL SOLUTION A REAL SOLUTION A REAL SOLUTION A REAL SOLUTION!
This a followup and I have a solution for the defrost timeout problemI posted a few days ago! The root cause is a manufacturing defect that I photographed the first time I took the evaporator chamber cover off the fridge on 9/29/17. Here are the specifics of my fridge which was purchased 3/30/16 Model #RF26J7500SR/AA S/N: <HIDDEN>)
I realized that the defrost sensor and the defrost power wires passed along and across the gasket that is supposed to keep air from passing where it shouldn't. This crushed the gasket and made it less effective. Apparently there was enough movement, perhaps from changing temperatures, that the air leaked more and more.
Once I realized the problem, I fashioned a section of foam-type material to fill in where the gasket had been crushed at manufacture. The results were dramatic! Now the defrost cycle runs anywhere from about 30 minutes to just under an hour. There are no more error messages either.
I have photographs to show what happened as well as samples of the power graphs. I have no doubt that Samsung was at fault and that it would be proper for Samsung to do the honorable thing and repair units like mine free of charge
