Hi Guys,

I have a Samsung RB1855SW. Few days ago the Evaporator fan started making a noise when its blowing (I thought fan going bad). Last night I noticed the noise stopped, so I checked the freezer and noticed an item had begun to thaw. I took the evaporator covers off. Noticed a lot of ice build up at the top and ice had reached fan. Spent 3h defrosting and putting it back together.
-I was pouring hotwater over the ice to defrost and also using the warmth of my hand to melt ice in hard to reach areas. Is there an easy way to defrost if I had to do this again?
-After letting it run for about 9h (starting at 19C) it got to -7C. (Set temp is -18C). I took off the cover and looked at the frost pattern and I see its iced up at the top in a similar manner again..

Will this melt away on its own?
Should I be concerned of the frost pattern? I believe I saw somewhere that this is a sign of low refrigerant?


I had a similar issue few months back where Freezer wasnt coooling but this ice build up in freezer wasnt present that time. That time there was some ice build up on fridge evaporator coils. I havent check fridge compartment yet but last night I did notice a bag of bread covering one of the vent areas in the fridge and there was a thin layer of frost in that area.. Fridge temp is fine though
If there was ice build up in fridge, could that impact freezer as well?


Thank you in advance for any input.
 
Yes, it looks like a sealed system problem.

The normal frost pattern is a thin layer of frost on all the coils from top to bottom.

Look at the very bottom photo below where it says NORMAL FROST PATTERN.
