Samsung refrigerator fan noise fix (step by step)

Samsung refrigerator been making grinding noise due ice buildup around copper pipe .
While fixing it I decided to begin my first KZbin video ever with this repair guide.
Hope it helps.
Timer (sort of long term solution): amzn.to/47MguS7 (Amazon)
Use it for the refrigerator, set it to be in off mode for 30 - 45 minutes to allow ice build (at the cooling coil), to melt off. Personally did this for over 2 years +
Also remember to vacuum the dust built up at the vent on the side bottom of the refrigerator.
Also pull entire refrigerator out, un-screw the metal plate at the back bottom and clean the built up dust inside.
