When to Repair vs Replace?

When deciding whether to repair or replace your Sub-Zero refrigerator, consider the following factors:

  1. Condition of Frame & Doors: If the steel box and insulation are in good condition, and the doors still close well, repairing the mechanical system is usually feasible. However, if there are irregularities on the frame that inhibit door closure, replacement may be a better option.

  2. Availability of Parts: Check if parts for your specific Sub-Zero model are readily available. Newer units are more likely to have accessible replacement parts.

  3. Service History: Consider the repair history of your refrigerator. If it has been reliable and well-maintained, repair might be worthwhile.

  4. Cost Efficiency: Compare the cost of repair to buying a new unit. Repairs are often more cost-effective, especially for older Sub-Zero models.

  5. Sizing Constraints: If your kitchen layout accommodates your existing Sub-Zero, repairing it could be simpler than replacing it.


Remember, repair is not just a viable option—it’s a smart choice that preserves your investment and maintains peak performance without compromising quality. Book an appointment today with a Fix It Guy Technician.

Tips on Care & Maintenance

 Proper maintenance is essential to keep your Sub-Zero refrigerator running smoothly. Here are some tips:

  1. Clean the Condenser Coils: Vacuum or brush the condenser coils every three to six months to remove dust and debris. This ensures efficient cooling performance.

  2. Inspect Door Seals: Regularly check the door seals for signs of wear or damage. If needed, replace them to maintain a proper seal and prevent energy loss.

  3. Keep the Door Closed: Minimize the time the refrigerator door is open to maintain consistent temperature and reduce strain on the compressor.

  4. Test the Door Gasket: Ensure the door gasket (rubber seal around the door) is intact and sealing properly. A faulty gasket can lead to temperature fluctuations.

  5. Leave Space for Air Circulation: Avoid overloading the refrigerator and freezer. Leave some space for air circulation to maintain optimal cooling efficiency

Remember, regular maintenance helps extend the lifespan of your Sub-Zero refrigerator and keeps it performing at its best! Book an appointment to get your Sub-zero maintenance checkup today!
