Compressor Noise
Unusual buzzing, clicking, or knocking sounds may indicate issues with the compressor or condenser fan. -

Change Water Filters

Monitor Temperatures
Ensure your fridge is set to 37°F (3°C) and the freezer to 0°F (-18°C) for optimal food preservation. -
Keep It Stocked—but Not Overloaded
Sub-Zero units work best when there’s enough food to retain cold air, but don’t overcrowd shelves, which can block airflow. -
Schedule Annual Check-Ups
Many repair companies offer maintenance plans. A yearly inspection can catch small issues before they become big problems.

When selecting a service provider, consider the following:
-
Is the company Sub-Zero certified or authorized?

-
Do they provide a warranty for their repairs?
-
Are they transparent about pricing?
Research thoroughly before hiring to ensure you’re entrusting your luxury appliance to capable hands.
