Why did I buy it Magic Chef problem

Question

Kind Sir or Madame-
I have a Magic Chef fridge.
The model number is MCBR1000W
Serial number A 040513448
Slim. freezer on top.
Evaporator fan is grinding to a halt.
Bad noise.
We have taken the rear inside freezer panel out and investigated.
Our attempts have not fixed problem.
Replace fan?
Throw refrigerator out window?
Actually, we can't afford to get rid of it, so fix it ideas will help.
Thank you.
