Sub-Zero refrigerators have a long lifespan, and with Sub-Zero refrigerator regular maintenance, they typically last between 20 to 30 years. However, there may be times when your Sub-Zero refrigerator fails to cool properly. This is not only an inconvenience but also a waste of food and energy. In this guide, we will explore several steps you can take to diagnose the problem when your refrigerator stops cooling and how to resolve it.

Adjust The Temperature Settings

Part of Sub-Zero Refrigerator Regular Maintenance is ensuring your thermostat is set correctly. For analog thermostats, set the dial to the middle position. For digital thermostats, confirm that the refrigerator is at 37°F and the freezer at 0°F. Incorrect settings can cause cooling issues, so be careful when adjusting or cleaning to avoid accidental changes.

Check the Door Gaskets

The door gaskets are crucial parts of your Subzero refrigerator. It’s important to inspect them regularly for any signs of damage. Over time, gaskets can become worn, loose, or torn, allowing cold air to escape and increasing temperatures inside the unit. Regularly wipe the gaskets with a soft, damp cloth to prevent damage.

Clean the Condenser Regularly

Another important part of Sub-Zero Refrigerator Regular Maintenance is regular condenser cleaning. Dust and dirt can clog condenser coils, reducing cooling efficiency. For optimal performance, be sure to clean the condenser coils at least once a year.
