Clean the Condenser

Core Issue:

  • How to clean the condenser
  • "Service" or "Vacuum Condenser" flashing
  • Sub-Zero running constantly or not cooling
  • Sub-Zero temperatures are warm or hot
  • Chemical cleaner or degreaser that can be used to clean the condenser


Perform condenser cleaning every six to twelve months to keep Sub-Zero refrigeration products operating their best.

  • Clean the condenser more often if pets are present.
  • Do not bend the aluminum fins of the condenser.
