Symptoms
- Water droplets on the outer door or cabinet
- Sweating worse in summer or humid rooms
- Moisture concentrated around door edges
- Occasional dripping onto the floor
Likely causes
- CommonHigh ambient humidity in the roomWarm, moist air condenses on the cooler exterior surface of the freezer, especially in basements or garages.
- CommonDoor gasket not sealing wellCold air escaping around a worn seal chills the surrounding cabinet surface enough to cause sweating.
- PossiblePoor ventilation around the unitTight spaces without airflow trap humid air against the cabinet.
- Less commonAnti-sweat heater failure (built-in models)Some models have a small heater strip around the door frame that can fail and stop preventing condensation.
What to do
- Check the door gasket seal using the paper test and clean or replace it if it's gapping.
- Improve ventilation by giving the unit a few inches of clearance from walls and cabinetry.
- Run a dehumidifier or fan in rooms with persistent high humidity, such as basements or garages.
- Wipe down condensation regularly to prevent water damage to flooring or cabinetry.
- If your model has an anti-sweat or energy-saver switch, check that it's turned on.
- If sweating is severe and constant despite a good seal, consider whether the unit is rated for the room's climate conditions.
Tools and parts
- Towel
- Dehumidifier (optional)

When to call a pro
If a built-in model sweats heavily and has an anti-sweat heater option, a technician can check whether that heater has failed.
