If your fridge smells bad but you cannot find any rotten food, the odor is likely trapped in hidden bacteria, mold, or spilled residue. To tackle this, clean the door gaskets and the drip tray, then place an odor absorber like baking soda or activated charcoal inside.
When an empty fridge smells bad, the odor is usually trapped in the plastic lining, the drain hole, or the drip pan. You can eliminate it by wiping the interior with a vinegar solution, clearing the drain, and leaving an odor absorber inside.
To fix a smelly fridge, immediately remove expired food, wipe down surfaces with a 50/50 mix of warm water and white vinegar, and place a fresh box of baking soda or activated charcoal inside to absorb lingering odors. For deep odors, clean the drain pan and gasket, or use coffee grounds to neutralize smells.
It Smells Like Dead Animals Or Rotting Meat!
Most likely, the smell is caused by either mold or mildew inside your fridge. This is most easily fixed by cleaning your fridge out.
Watch for warning signs like food spoiling prematurely, clicking or buzzing noises, continuous motor running, or excessive frost/condensation. Older units often cost more to repair than replace.
The average refrigerator lasts between 10 to 15 years. However, this lifespan varies significantly based on the style, brand, and how well the appliance is maintained.
Discard refrigerated perishable food such as meat, poultry, fish, soft cheeses, milk, eggs, leftovers, and deli items after 4 hours without power or 2 hours after the temperature rises above 41 °F. At any time, discard spoiled, moldy food and anything that does not look or smell right.
Most Common Causes
A Freon leak in a refrigerator generally has a subtle chemical or sweet odor. While pure Freon is naturally odorless, a leak can produce scents frequently described as:
Replace your refrigerator when it is 10–15 years old, breaks down frequently, or requires a repair costing over 50% of a new unit's price. Key indicators include consistent food spoilage, excessive noise, or high energy bills, as older models are significantly less energy-efficient than modern Energy Star units.
Depending on how strong the odor or smell is, it may take a few weeks or months for penetrating odors to go away. Some odors may have been absorbed into your refrigerator's insulation. If odors cannot be removed, it may be time to shop for a new refrigerator or freezer.
To get a bad smell out of your fridge quickly, do a deep clean with a 50/50 mix of white vinegar and water, and then place a shallow bowl of baking soda, fresh coffee grounds, or activated charcoal on a shelf to absorb any lingering odors.
One possible cause of refrigerator odor may be spoiled food. Remove and discard anything that has spoiled and keep your refrigerator organized to help eliminate the chance of forgetting about items before they go bad. You can also double check that lids are on completely for food items that have stronger smells.
To Remove Odors from Refrigerators and Freezers
Dispose of any spoiled or questionable food. Remove shelves, crispers, and ice trays. Wash them thoroughly with hot water and detergent. Then rinse with a sanitizing solution (1 tablespoon unscented, liquid chlorine bleach per gallon of water).
Musty or Earthy Odor
Mold releases microbial volatile organic compounds (MVOCs), which create that unmistakable “old house” scent. If this odor consistently comes from the fridge area, it's a strong indicator of moisture and mold development.
Medium Risk: Washing machines, dishwashers, and fridge-freezers fall into this category. Faults in their complex electrical systems, pumps, or compressors can lead to overheating and fire, especially as the appliances age.
Freon (refrigerant) poisoning usually occurs in confined, poorly ventilated spaces. It can cause mild symptoms like headaches, dizziness, and nausea, and more severe, life-threatening effects like irregular heartbeats, fluid in the lungs, seizures, and loss of consciousness.
According to the United States Department of Energy, refrigerators last approximately 12 years. At that point, it's likely time to replace it. Of course, if your refrigerator is not energy-efficient, you may want to consider replacing it before it stops working.
A smelly fridge is usually caused by trapped food particles, mold, or bacteria that have soaked into plastic, gaskets, or filters.
There's a Funny Smell
You can clean and scrub the inside of your fridge freezer as much as you can, but sometimes it's just not enough. If the odour smells like strong chemicals or gas, then your fridge freezer could be leaking refrigerant. Inhaling this can be very dangerous! If it's safe to do so, turn the unit off.
Yes. A broken fridge frequently smells, usually due to food spoiling as temperatures rise or because of mechanical failures like a gas leak.
What foods should not be refrigerated?
Non-profit organisation Love Food, Hate Waste recommends the 2:2:2 rule. Two hours to get them in the fridge. Two days to eat them once they're in there. Or freeze them for up to two months.
