Freezer
Smells Bad

A freezer smells bad when you lift the lid or open the door, a sour or stale odor that clings to ice cubes and packages, and returns after you wipe the shelves.

What it
usually means.

Cold slows down odors but does not stop them. A bad smell in a freezer usually has one of three origins. The first and most common is food: a package that thawed during an outage and refroze, a spill that froze into a corner, or meat that leaked under a basket. The second is water that sat where it should not: a drain pan under the cabinet holding stale melt water, or a drain tube lined with slime. The third is the appliance itself: a burning smell from an electrical part, which is a different and urgent problem, or a chemical smell after a repair. Knowing whether the smell is inside the cabinet, under it or at the back tells you which of the three it is.

Answer these first

01

Is the smell inside the cabinet, under the freezer or at the back?
02

Was there a power outage or a thaw in the last few weeks?
03

Is the smell sour and rotten, musty, or sharp and burning?
04

Does it cling to ice cubes stored inside?
05

Is there water in the drain pan under the cabinet?

before you book.

Freezer smells bad: 5 checks, and none of them costs anything.

01

If the smell is sharp and burning, turn off the breaker only from a dry panel and see the burning smell page.

02

Move the food to a working freezer or a cooler with ice before cleaning, and discard anything that thawed and refroze with an off smell.

03

Wash the cabinet, the baskets and the gasket with warm water and baking soda, then dry them fully.

Also worth checking

  • Check the drain pan under the cabinet and the drain plug on a chest model.
  • Leave an open box of baking soda inside for a few days after cleaning.

How soon does it need a visit?

A food smell is not urgent, though it may be a sign of an outage that damaged food. A burning smell is urgent and needs the breaker off from a dry panel; a musty smell under the cabinet can wait for a visit.

5 things freezer smells bad turns out to be, from thawed and refrozen food to electrical smell from a part.

The cost guide
  1. 01 no repair

    Thawed and refrozen food

    Juices that leaked during a thaw freeze into the liner and the baskets. Remove the food, wash the cabinet with warm water and baking soda and dry it before restarting.

    No repair: check it yourself
  2. 02 no repair

    Odors from uncovered food

    Fish, onions and open packages pass their smell to everything else, especially ice. Sealing food and an open box of baking soda help.

    No repair: check it yourself
  3. 03 low

    Stale water in the drain pan

    Melt water that does not evaporate grows a musty film in the pan under the cabinet. Cleaning the pan and checking the drain clears it.

    Fixed by freezer drain and defrost water repair
  4. 04 low

    Slime in the defrost drain

    Drain tubes on frost-free models can grow a film that smells each time the defrost runs.

    Fixed by freezer drain and defrost water repair On an upright freezer
  5. 05 varies

    Electrical smell from a part

    A sharp hot-plastic smell is not food; it belongs on the burning smell page and needs the power off.

Questions about
freezer smells bad.

The freezer smells after a power outage. Is the food safe?
The smell itself does not tell you. Check whether the food still has ice crystals or stayed at 40°F or below; that is the FDA test. Anything spoiled needs to go, and the cabinet a good wash.
Can I use bleach to clean the cabinet?
A mild solution of warm water and baking soda is safer for plastic liners and gaskets. Strong cleaners can leave an odor of their own that the food picks up.
Why do my ice cubes taste like the freezer?
Ice absorbs smells from open food. Sealing food and cleaning the cabinet usually solves it.
The smell comes from under the freezer, not inside. What is it?
Most often stale water in the drain pan or a spill that ran underneath. Unplug the freezer before cleaning around the base.
