I have a smell in my refrigerator that I can't seem to get rid of.

after making sure all the food is good, try an open dish or two of baking soda. also check the tray where the condensed water goes to.

Did you pull out your vegetable bins? This happened to me and I found that something leaked and went to the bottom of the fridge. I also use baking soda. Just put an opened box of baking soda in the fridge and change it every 2-3 months. It will absorb odors.

Remove everything from the fridge and give it a good cleaning. Then put a box of baking soda inside to help keep odors at bay

Are you sure it's in the fridge and not under the fridge?

charcoal and newspapers also absorb orders if the baking soda doesn't work.
