Symptoms
- Ice cream is soft instead of firm
- Frozen food feels partially thawed
- Freezer runs constantly
- Frost buildup is uneven or heavy in spots
Likely causes
- CommonOverpacked freezer blocking air ventsCold air needs to circulate; food pressed against interior vents stops even cooling.
- CommonDoor not sealing fullyA worn or dirty gasket lets warm air in constantly, making the unit work harder without reaching target temperature.
- CommonTemperature set too warmSimple dial or digital settings can get bumped or need adjustment for full freezing.
- PossibleDirty condenser coilsDust-covered coils reduce cooling efficiency, especially in units with coils underneath or behind.
- Less commonFailing evaporator fan or compressorIf air isn't moving or the compressor is weak, the unit cannot maintain freezing temperatures.
What to do
- Rearrange contents so nothing blocks the interior air vents or fan area.
- Set the temperature to 0F (-18C) and allow 24 hours to stabilize before checking again.
- Wipe down the door gasket and check for gaps using the paper test (close the door on a strip of paper and see if it pulls out easily).
- Unplug the unit and vacuum any exposed condenser coils, usually at the back or bottom.
- Make sure the freezer has clearance from the wall for airflow, typically a couple of inches.
- Listen for the interior fan running; if you hear nothing when the compressor runs, the fan may have failed.
- If temperature still won't drop after these checks, call an appliance technician to test the compressor and sealed system.

When to call a pro
If the gasket, coils, and settings are all fine and the freezer still won't reach temperature, have a technician check the compressor and refrigerant system.
