Samsung I had same problems everyone experienceing with frost and ice jamming. The ice bucket and auger assembly were the latest so I worked from there to resolve the issue. 1. sealed the ice room......problem persists. 2. pulled auger assembly, checked fan motor to ascertain it worked...running fine with 12VDC. 2a. With auger Assy removed checked the water inlet tube. Found it properly positioned. 3. installed drip clips on ice maker evaporator coil.....problem persists. 4.checked dispenser door and ice bucket sealing...all sealing well. 5.tilted refrigerator .....problem persists Now comes my deduction. I noticed that the ice room fan had a third wire. Well, on computer fans, which are similar, this is usually an indication of a PWM motor which changes speed dependent on temperature. Nowhere could I find how to check the fan while the fridge is running...nowhere. My deduction was to first replace the main control board. Well, that did resolve the ice maker frosting up. It's been 2 months and not a hint of frost and more than enough ice. It is opinion the ice room fan operation is critical in keeping frost from building and jamming of cubes. Somehow, Samsung must find a way to determine the ice room fan operation when all the parts are in place and fridge running.

Change the master control board. I did which solved my ice maker problems. You can find the board online for dirt cheap. It's also very easy to replace. Several screws and about 10 plugs that are very nicely tied into a wiring harness that you can't make a mistake when plugging them into the new board. I went about methodically to find this and it was the last resort. Hopefully it'll work for you.
First I checked the seals on the ice bucket and the dispenser door. Dispenser door held water, ice bucket seal was checked with strips of paper. Both were good.
As most everyone has done I sealed the ice room. Still building frost and jamming the ice maker.
Checked the position of water tube. It was dead center.
Checked to make sure the fan ran by removing the augerdrive and powering the fan with a 12 VDC power supply. It ran fine. Used front leveling screws to tilt the fridge slightly backwards as some recommended. No help. Still frosting up and jamming.
Out of frustration, replaced the control board. Been 2 months with zero frost and no jamming.

I had the same issue with a fridge purchased in 2017. End of 2019 the touch pad started switching by itself arbitrarily between water, crushed and cubed ice. A month later the ice frost and jamming started. Defrosting the ice room helped for a 1-2 weeks depending on usage. This fridge had all the newer parts that were called for to correct this problem except for the drip clips on the evaporator. Didn't believe the clips could resolve this problem I systematically tried each of the published repairs. The ice door and seals were checked first and all were found to be sealing properly. Sealing the ice room, didn't work. Adjusting the water inlet tube didn't work. Tilting the fridge didn't work. Installing the evaporator drip clips didn't work. Having removed the ice auger drive I ascertained that the fan was working by powering with a 12 volt battery. Seeing that the fan had 3 wires I suspected that it might be a pulse with modulating motor similar to those used for cooling-computers. Since I was having other control problems I opted to replace the main control board. I purchased an OEM board. From pulling the fridge, replacing the board,to pushing it back took about 10 minutes. The way the board and the wiring harnesses are designed it is extremely difficult to make a mistake. Really well designed. The fridge has been working for 6 weeks with absolutely no frost buildup and the touch pad problem resolved. In my opinion, I suspect there maybe a systemic problem with the fan control circuit components creating everyone problems. The board can be purchased thru a third party at a very reasonable price.
