It is hard to imagine at least one day without a refrigerator. When your Sub-Zero stops working, life is not exuberant any more. Any appliance, regardless of brand, model or cost, can fail. As a rule, that happens suddenly. There are many reasons why it may occur. Unfortunately, in many cases the refrigerator stops working due to the owner's violation of the operating rules. At the same time, there are times when the refrigerator does not work as a result of time and exhausted parts. Only a professional service technician can determine the exact cause of a cooling issue. Use this troubleshooting as a starting point to resolve warm refrigerator temperatures.
- Check the setpoint temperatures for the compartment. Always allow 24 hours for the unit to reach a new temperature setting.
- On an electronic control panel, 38°F is the recommended setting. For a dial control, set the dial between 4 and 6. 1 is warmest, and 10 is coldest. 200, 300, and 500 Series Sub-Zero products have dial controls.
- Verify the door closes and was not left ajar for a long time. Turn the door ajar alarm on if it is not on to make sure the door is closing all the way.
- Correct or remove anything blocking the door from closing.
- Check the door gasket or rubber for damage.
- New groceries or warm food will raise temperatures for a time. Temperatures should return to normal after several hours.
- Clean the Condenser if it was not cleaned in the last 6 months.
Verify if only one or all sections are not cooling. This information is helpful if service is necessary. Wait 24 hours for the unit to return to normal temperatures after correcting any or all of the above. If the refrigerator is still warm after these steps are complete, service is necessary to expertly diagnose and repair the product. Remember that you should start self-repairing the refrigerator only when you have visually determined the cause of the breakdown. DIY can lead to further damage. In this case, the cost of repairs will increase significantly.
