A Liebherr fridge smells for one of a few reasons: spilled or spoiled food somewhere you cannot see, strongly scented food sharing circulating air, a saturated odor filter, a blocked drain with standing water, or a drawer or seal that has gone musty. Empty the cabinet, find and remove the source, wash the interior, check the drain and the filter, and the smell usually goes. A smell of burning is different and is covered below.
Why does a Liebherr fridge smell?
A refrigerator is a closed box with moving air. A smell means something in that box is giving off odor, and the air carries it to every shelf. In a fan-cooled cabinet this is especially true, because the same circulation that keeps the temperature even also spreads smells. Our guide to the FreshAir filter makes the point: butter next to an open dish of curry is a well-known result. So the first job is to find the source, and the second is to deal with the air path.
Smell is also a reminder that cold does not stop spoilage. Cold slows it. Food that has been in the cabinet too long, or has leaked, will smell regardless of the temperature.
Where is the smell coming from?
Empty the cabinet shelf by shelf and use your nose. Check the back of the shelves, the bottom of the cabinet, door bins and the area under the lowest drawer, where spills run and sit. Look at packaging that has torn, jars with leaking lids and produce that has gone soft at the bottom of a drawer. Raw meat or fish packaging that leaked is a common culprit. Wash anything suspect in the sink with warm water and a little dish soap, and throw out spoiled food.
Do not forget the less visible places. A spill can run down behind a drawer or into the base, and a smell that returns after a thorough clean often points there. Take the drawers out; our BioFresh drawer cleaning guide shows how to lift a drawer off its runners and wipe the runners and the glass cover.
Could the odor filter be the cause?
Possibly. The FreshAir filter is a small activated-charcoal cartridge in the air path, and it works by trapping odor molecules as the air passes. It is a consumable. Once it is saturated it does nothing, and it gives no warning. Signs are foods tasting of each other, a general stale refrigerator smell when you open the door and a cabinet that smelled fine a week ago after a thorough clean. Our guide on how FreshAir filters work describes where the housing sits and how to change the cartridge: note the orientation, fit the new one the same way and write the date down. The manual lists how often to replace it. Not every model has the filter, so check yours.
Is the drain or the door seal involved?
Water that stands at the base of the cabinet goes stale and smells. In a frost-free model, meltwater runs to a drain channel at the back; if it blocks, water pools. Our guide to condensation inside a Liebherr fridge says to clear the channel gently with a cotton swab and warm water, never with wire. A door gasket with a film of old spills or mold in its folds can smell as well, and a gasket that does not seal lets humid air in, which feeds damp odors. Wipe the folds with warm water and dry them, and see our door seal replacement guide if the gasket is torn or hard.
How do you clean it so the smell stays gone?
Wash shelves and drawers by hand in warm water with a little mild dish soap, and wipe the walls and the ceiling with a soft cloth. Rinse with a cloth dampened with plain water and dry everything before it goes back. Avoid strongly scented cleaners; a refrigerator keeps whatever you spray in it. A solution of baking soda in warm water is a gentle choice for odors. Let glass shelves reach room temperature before washing. Our annual maintenance checklist shows the routine, and an open container of baking soda on a shelf can help with minor smells, though it is not a substitute for removing the source.
Keep strong foods in sealed containers afterward. Wrap cheese, cut onion and fish well, and cover leftovers. That alone prevents most repeat smells.
When is the smell a safety problem?
A smell of burning, hot plastic or electrical overheating near the refrigerator is not a cleaning problem. Switch off the breaker at the panel while standing on a dry floor, do not pull a plug from a wet outlet, and call for service. If you smell gas in the kitchen, do not switch anything on or off. Leave the house and call your gas utility or 911 from outside. A rotten smell after a long power cut is spoiled food, and our power cut guide covers what to do with it. If the smell persists after a thorough clean and a new filter, our refrigerator repair page explains how a visit works.
