Rotten foods are the number one culprit, closely followed by improperly stored leftovers. Spillage inside a fridge can also contribute to nasty smells. Also, many people forget to clean out the drip pan at the bottom of the fridge. After extended periods, the water in the pan becomes dank and can smell really bad.
Getting rid of smells inside fridges is pretty simple
