Dryer not spinning

I took off the front panel via 2 screws on the inside of the dryer with the top panel in the maintenance position. Pulled out the tub(cut my hand pretty bad in the process but continued). Did some cleaning and I had to google how the belt tensioner goes into place. Rather difficult on your own i held the belt and placed the tub back into place while placing the belt around the tub putting it in the correct area. thats pretty much it and began reinstalling the parts i had removed.. easy fix now that i have done it once. This is all after my landlords said they werent replacing it and just to have this one hauled off, so all in all i have a 26 dollar dryer now:)
