I have a RF22KREDBSG/AA <EDIT>. Our ice maker froze over last May of 2018 after owning the unit for a little over a year , we called Samsung and they advised out of warranty but they would go ahead and send repair company to fix under warranty. MetroTech (Greenville, SC) came out and replaced the entire ice maker at no cost to me. Now a year later (May 2019) the ice maker doing the exact same thing freezing over. Called Samsung and was told they did 1 time free fix and nothing they would do now. I explained to the rep that it is doing the exact same thing and I explained that there is a 2017 Tech bulletin that describes my issue. They basically said sorry you have to pay. I explained that I just remodeled last year and all my appliances are Samsung. They did not care!!! I called MetroTech to get a price and they advised $300 but they also told me that Samsung just issued a repair kit 2 months ago that is suppose to fix. I have not scheduled yet. If I was having any other issue I would understand being out of warranty but this is a well known issue by Samsung and all I can do is hope they might do the right thing.
You can try defrosting with a hair dryer. Make sure to defrost the far back of the unit. Dry up any water.
The ice maker frosts over due to most air getting into it. Inspect the dspensor flap to make sure it isn't stuck open or warm room air will get in. Inspect the gasket that mates the ice maker to the refrigerator door. You can view it by opening the other refrigerator door.
Lastly take a flash light and shine it at the bottom of the ice maker from the fridge side. Look inside the ice maker and look for a gap where the ice maker meets the left wall of the fridge and light shines through. If so, remove the screw holding the trim in the ice maker and run a bread of caulk along the seam.
Leaving the left refrigerator door open during normal use will allow air into the ice maker through the hole. Minimize leaving the door open.
I have the same issue with mine. I purchased the fridge in Feb. of 2018, two months later the problem started. I've been dealing with this stupid fridge ever since and regret ever buying this poor quality appliance. I have extended warranty on it, so every time it goes out, I call the techs. They replace the icemaker and seal it every time. Two to three months later, the issue reappears. I've had my icemaker replaced at least 6 times now. Samsung is clearly producing defective icemakers. The store where it was purchased refuses to exchange the product claiming that as long as it’s repairable it won’t be exchanged. Basically, I'm stuck with this fridge. The warranty covers the repair costs till the year 2020, after that, I'm on my own. It’s beyond frustrating that a $4k+ appliance would be such poor quality. To make things worse, no one takes responsibility for it, neither the manufacturer nor the store. They are only out to take my $$$$. I’m convinced it’s a total scheme.
I have model RF24J9960 refrigerator, part of the Samsung Chef Collection series. The ice maker stops working every couple of weeks with heavy frosting inside. I need to manually defrost it, which is a real pain. I have several other Samsung Chef Collection appliances, and many of them have serious quality problems. Any advice on how to get this one really fixed? My old Samsung refrigerator, also a French Door model, which we stil have, never had this problem.
