In Sub-Zero refrigeration units, the door and drawer self-closing operation plays a crucial role in maintaining optimal temperature and preserving food freshness. Understanding how these mechanisms work is essential for ensuring the efficient functioning of your Sub-Zero appliance. In this article, we will explore various aspects of Sub-Zero door and drawer self-closing, including when the doors should close on their own, the presence of soft-close features, troubleshooting steps, and more.
Sub-Zero refrigeration units are renowned for their exceptional quality and advanced features. Among these features, the self-closing operation of doors and drawers ensures that your food remains fresh and protected from external factors. Let’s explore how this operation works for different Sub-Zero series and models.
Should the door or drawer on a 500, 600, Classic (CL, BI), Designer (DET, DEC, IT, IC), 400, or 700 Series unit close on its own?
Yes, the doors and drawers on these Sub-Zero series units are designed to close automatically. This feature ensures that the refrigerator remains properly sealed, maintaining the desired temperature inside and maximizing energy efficiency.
Should the door on a 400, 500, 600, BI, IT, IC, or 700 Series stay open?
No, the doors on these series should not stay open. The self-closing mechanism is engineered to gradually close the door when it reaches a certain angle, usually around 45 degrees. This ensures that the doors are never left ajar, preventing temperature fluctuations and potential food spoilage.
Which interior drawers have the soft close feature?
Classic Series (BI, CL), Designer (DET, DEC, IT, IC), and Designer Column IC-27R models include soft-close refrigerator drawers. However, the interior freezer drawers do not have this feature.
Do Sub-Zero interior drawers have a self-close feature?
Yes, Sub-Zero interior drawers, particularly the refrigerator drawers with soft-close mechanisms, have a self-close feature. As you close the drawer, the soft-close mechanism and drawer slide catch the drawer and gently pull it closed.
When should the refrigerator drawer close by itself?
The soft-close mechanism engages when the refrigerator drawer is within approximately 1″ of being closed. At this point, you will feel a “catch” as the mechanism takes over and closes the drawer with a smooth pulling action.
Do 200 and 300 Series units have a self-close feature?
No, the 200 and 300 Series units do not have a self-close feature. These models operate without the soft-close or self-close mechanism.
Self-closing feature is not working
If you encounter issues with the self-closing feature on your Sub-Zero unit, there are troubleshooting steps you can follow to resolve the problem. Please refer to the Sub-Zero Door and Drawer Self-Close Not Working guide for detailed instructions.
Troubleshooting steps for Sub-Zero Door and Drawer Self-Close Not Working
If the self-closing feature is not functioning correctly, try the following troubleshooting steps:
- Check for any obstructions that may prevent smooth movement of the doors or drawers.
- Ensure that the doors and drawers are properly aligned.
- Clean the tracks and slides of the doors and drawers to remove any debris.
- Lubricate the tracks and slides with a recommended lubricant.
- Verify that the unit is level to allow the doors and drawers to close properly.
- If the issue persists, it is recommended to contact a Sub-Zero service professional for assistance.
Self-Closing in Professional Series (PRO3650, PRO4850, 648PRO)
Professional Series units, including PRO3650, PRO4850, and 648PRO models, do not have a self-close or soft-close feature. The doors on these units operate without any automatic closing mechanism.
Self-Closing in Over/Under and French Door Models
For Over/Under and French Door models, the refrigerator door utilizes a door closing cam to assist with closing. The cam engages at a specific angle to facilitate smooth and controlled door closure. Additionally, the bottom freezer drawer in these models does not have a soft-close feature.
Self-Closing in All Refrigerator, All Freezer, Side-by-Side, and UC Undercounter Models
In Classic (BI) models, the hinge holds the door open at 110° and takes over at approximately 15° to help close the door. For 500, 600, and 700 Series models, the door cam aids in closing the door from around 45° open. Freezer baskets and drawers in these models must be manually closed completely.
Undercounter (UC) models, including an upgrade in 2014, utilize a spring-loaded closure mechanism for the refrigerator and freezer doors. As the doors are closed, the door closure engages, ensuring proper sealing and closure. The newer type door closer employs magnetic assistance to help close the door when partially opened. Designer Undercounter (DEU) models, however, do not feature a self-close or soft-close mechanism.
Self-Closing in Wine Storage
In the 400 Series model, the hinge holds the door open at 110°, and the cam takes over at approximately 15° to assist with door closure. Wine storage units from Sub-Zero provide a soft-close feature, enhancing the overall experience by providing noiseless operation and a premium feel. The soft-close feature slows down the closing action, ensuring the doors close fully.
Self-Closing in Designer Refrigeration
Designer Refrigeration models offer a soft-close feature that provides a rich and sturdy feel to the unit. This feature contributes to noiseless operation and ensures the doors close completely. The bottom freezer drawer in these models does not have a soft-close feature.
