Coldest Part of a Refrigerator or Freezer


  • Where is the coldest spot in a Sub-Zero refrigerator or freezer?
  • Is the bottom of a refrigerator colder or warmer than the top?
  • Upper shelf is warmer than the bottom shelf


Sub-Zero refrigeration units offer a superior airflow system for more consistent and uniform cooling results.

  • Even with a superior airflow system, a refrigerator or freezer will be colder at the bottom.
  • Warm air rises, so the upper shelves will always be slightly warmer than the lower portion of the unit.

Refer to the product Use and Care Guide for further information.
