Sub-Zero Door and Drawer Self Closing Operation

Topics:

  • Should the door or drawer on a 500, 600, BI, NGI, 400 or 700 Series unit close on its own?
  • Should the door on a 400, 500, 600, BI, NGI, or 700 Series stay open?
  • Which interior drawers have the soft close feature?
  • Do Sub-Zero interior drawers have a self-close feature?
  • When should the refrigerator drawer close by itself?
  • Do 200 and 300 Series units have a self-close feature?

Answer:

Classic (formerly Built-In) Series, Designer (formerly Integrated) Column, and Designer products have soft-close refrigerator drawers. Interior freezer drawers do not have the soft-close feature.

  • As the interior refrigerator drawer closes, the soft-close mechanism and drawer slide will catch and close the drawer with a soft-pull action.
  • The "catch" of the soft close will be felt once the drawer is within approximately 1" of being closed.

Over/Under and French Door Models

  • The refrigerator door has a door closing cam to help close the door.
  • For a Classic (BI) model, with the door opened to 110°, the hinge will hold in the open position if the door stops. As you close the door, the cam will take over at about 15° to help close the door.
  • For 500, 600, Designer, and 700 Series models, the door cam helps close the door starting at about 45° open.
  • Door flexing is possible if a door swings open by itself under its own weight, it may flex a bit more than the maximum opening degree.
  • The bottom freezer drawer does not have a soft-close feature.

All Refrigerator, All Freezer, Side-by-Side, and Undercounter Models

  • For a Classic (BI) model, with the door opened to 110°, the hinge will hold in the open position if the door is stopped. As you close the door, the hinge will take over at about 15° to help close the door.
  • For 500, 600, and 700 Series models, the door cam helps close the door starting at about 45° open.
  • For 500, 600, and 700 Series models, freezer baskets and drawers must be manually closed all the way.
  • For Undercounter (UC) models, the refrigerator and freezer doors have spring-loaded closure mechanisms. As the doors are closed, the door closure engages to help close and seal the doors.
  • Undercounter (UC) models had an upgrade to the closer mechanism in 2014.
  • The new type door closer uses magnetic close help to close the door when partially opened.

Wine Storage

  • For the 400 Series model, with the door opened to 110°, the hinge will hold in the open position if the door is stopped. As you close the door, the hinge will take over at about 15° to help close the door.

Designer Refrigeration

  • The soft-close feature, found on high-end cabinetry, gives Designer Refrigeration a rich, sturdy feel and noiseless operation.
  • It slows down the closing action for smooth operation and helps to make sure the doors close fully.
