Sub-Zero Door Difficult to Open

Core Issue:

  • Why is the door hard to open?
  • Hard to open refrigerator or freezer door is stuck closed
  • What causes the door vacuum to be so strong?
  • Why do I have to use both hands to open the refrigerator door?
  • Door does not open as easily as before?
  • Is there any lubricant to use to lubricate the door from sticking so hard?
  • Door frozen or stuck shut

Steps to Verify Issue:

  1. Wait several seconds (up to 60) after the door is closed for pressure to equalize before reopening the door.
    • This may be a normal condition as Sub-Zeros are designed for an airtight seal.
    • Ambient room air mixed with the cold compartment air creates a vacuum until the pressure equalizes.
    • The greater the difference in temperatures the longer the vacuum may last.
  2. If the door does not open after a minute of closing it, open the door when possible and inspect the door gasket.
  3. Inspect the back wall of the refrigerator for condensation, frost or ice build up and refer to Frost on Back Wall if needed.
  4. Check for an ice buildup in freezer.
  5. Clean the condenser.
  6. Remove the unit’s crisper drawer and crisper shelf assembly; if equipped, remove all lower storage drawers as well.
  7. If there is condensation, water, or ice near, behind, or underneath the drawer(s) check for food debris, standing water, or ice built-up in the drain trough or drain tube located along the back wall. The drain trough and drain tube are visible on 200, 300, 500, or 600 Series Sub-Zeros.
  8. The drain tube may be clogged.
  9. Avoid lubricating the plastic face frame of Built-In, 400, 600 and 700 series units as the face frame can crack or deteriorate when exposed to lubricants like Vaseline.
  10. If all other options fail, it may be necessary to demagnetize the door gasket. This procedure should be performed by a Factory Certified Service.
