Freezer worked great, refrigerator would not cool

Removed (unsnapped) plastic cover from back of refrigerator ( inside freezer compartment), determined that the fan was not turning, removed 4 screws from the aluminum back plate in freezer and tilted it down. Removed 2 screws with a nut driver, this allowed the fan to be removed, unpluged fan motor from the bace of the freezer and removed fan. Installed new motor and spent $38.00 to repair the refrigerator that would have cost me severial hundred dollars to replace. Thanks for the help
