• What is the wooshing sound when closing refrigerator or freezer door?
• Wind or air sound

Answer:

When closing a Sub-Zero refrigerator or freezer door, it is normal at times to hear a wooshing or wind type sound. This is simply air equalizing through the drain lines.

• This sound is variable and can be intermittent.
• Variables include but are not limited to: ambient temperatures, ambient humidity levels, food load, temperature differential, etc.
• Inspect the door gasket. A tear can allow air to escape when the door is closed, causing a high pitched wooshing sound. See Sub-Zero Door Gasket Replacement.
