Samsung Fridge Defrost (RF28HMELBSR/AA)

[InoSiX]

This is a battle I have had for years now. I stumbled into this website during my first attempt to resolve my issue but it seemed it was clearly targeting service folk. I'm back at attempting to deal with my issue some years later (last time was 2019). This website seems to be the only one that seems to have a service manual for my particular Samsung Fridge. Specifically I have: 

Samsung RF28HMELBSR/AA

I have had to de-ice my ice maker every few weeks. I purchased a counter top ice maker and simply disabled my fridge's. Suddenly all this time later the internal fridge fan has started making lots of noise. I cannot remove the back plate to gain access to the fan and I suspect it is frozen. In many many threads/forums/ect I see references to be able to access FF or FD functions (FORCE DEFROST). The steps vary but ultimately none of them remotely close to match my 8" touchscreen that has none of the physical buttons being pressed.

I am at my wits end. Is there a chance I could get some assistance? It would be great to purchase a service manual, but absent that, the ability to make use of the FORCED DEFROST mode on my Samsung Fridge.

if you unplug it for 2 days it would defrost it... you probably should check the drain hose in the back check the top duck bill for a clog... also it would take 3 hours ask me how I know but a bissell steamer will help.... no matter what you have you defrost it to get access to the evaporator just make it easier by letting it defrost... you will have water flowing from the melted ice.
