Fridge was warm. No air circulating at all. Food was spoiling Fridge was just over 1 year old

First I removed the two screws that secure the guard in bottom back of the freezer and removed it . Next I removed the two screws that secure the guard on the back wall of the freezer and removed it. There are three wires connected to the motor, I unplugged those and removed the two screws that secure the motor and removed it. I swapped the grommets, blade and support bracket from the old motor. I put it back together in reverse steps and its working great. My mother-in-law can,t stop thanking me ! I saved her at least $400 to buy a new fridge. Thank You, Brian Miner
