Same Problem Different Fridge-Rotten Vegetable Smell

I've emptied the fridge and freezer cleaned it with baking soda mixture, bleach mixture and natural cleaners. Had it open and off for 3 days. I've cleaned the coils and the water catcher. The smell is back. The back and bottom of the unit does not smell. Only the inside of the fridge and I think the smell is migrating into the freezer and thereby making ice cubes taste funny. Could the issue also as the other post be the ice maker motor? It's a Maytag MBR2255KES bottom freezer w/ice maker.

BTW I don't tend to keep a lot of food in my fridge so not much has chance to rot.

Thank you
