Vinegar. Put a small dish of vinegar with some newspaper around it and leave it with the door closed over night. Vinegar is a strong deodorizer and newspaper is good for absorbing smells. Hope it works :)
1/2 cup vinegar and 1/2 cup water in a microwave safe container. Microwave on high 2 minutes. Careful when you open due to steam, wipe out all the old food and spills. Your "foul" smell should be gone too. Any type of vinegar works.

First taka out all removable shelves or rotating trays and mechanisms. clean them separately with dish detergent or in a dishwasher if safe to do. Clean the interior first with vinegar than with a strong solution of baking soda and water. Don't forget to rinse with a wet sponge.
