Convection oven-whirlpool

My whirlpool freestanding electric range is older than I thought-it just turned 6yrs lol. All works great,oven works BUT when I want to use convection bake &/or convection broil it makes the most awful noise & the fan at the back will not turn. Can I replace this part myself or do I need tech?

You can probably handle it your self. Just unplug the unit and don’t forget where the parts go back into :o)
