Deep clean your fridge

If you've followed the steps above and are still struggling with a lingering odor, it's probably something else in the fridge or freezer where you can't easily see or reach the source of the odor. You may need to go to the back of the unit to see if there is buildup on the evaporator coils. To do this, leave the refrigerator turned off and make sure you have unplugged all cables when you are outside. Check big double door fridge online.
