Sub-Zero Door Makes Wooshing Sound


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


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.
