Hello Fallen5729, You could try putting charcoal in your freezer. It's an old remedy and supposed to remove odors well. Hope this helps you. Good luck.

Although temporary, if nothing else works, I have had success putting a small container with a cotton pad saturated with vanilla extract.

Have you cleaned the water catch try underneath frig? And have you cleaned the drain at the bottom under the crisper trays or just above the crisper on the ledge. Pour some hot water in it, and use a pipe cleaner.
