Once you've checked all foods I'm fridge, cleaned thoroughly (including checking & cleaning drainage hole), stick an open pot of bicarbonate of soda in fridge as it will absorb any lingering bad smells. You can then pleasantly fragrance fridge naturally by putting in half a lemon freshly cut open or a couple of cotton wool balls with drops if vanilla extract on.
If something spills down the drainage hole the bottom of the fridge and into the drip tray and goes moldy it will stink. If you pull the fridge out and look behind it for the drip tray you may find the source of the smell (someone split grated parmazan cheese in my fridge and it was washed off down the drainage hole, you can imagine the smell ).
have you cleaned out the drainage hole at the back of the inside of the fridge? There is also some sort of tray thing on the back of the machine that you could have a look at too in case there are mouldy things in it
