How to fix a sub-zero refrigerator door that is not closing properly?

To fix a Sub-Zero refrigerator door that is not closing properly, follow these steps:
1. Check for obstructions: Ensure there are no items blocking the door's path, hindering it from closing fully.
2. Inspect the door gaskets: Check the rubber door gaskets for any signs of damage, wear, or debris. Clean the gaskets and, if damaged, replace them to create a proper seal.
3. Adjust the leveling legs: Use a wrench to adjust the leveling legs at the front of the refrigerator to ensure it is level, and the door closes smoothly.
4. Tighten hinges and screws: Check and tighten any loose hinges or screws on the refrigerator door.
If the issue persists, consider contacting a certified Sub-Zero technician for a more in-depth inspection and repair.
