Many things can cause your Sub-Zero refrigerator’s temperature problems including:
- One of several fans in the unit may not work properly
- Temperature sensors or the thermostat that tells the unit to cool can malfunction
- A sealed system problem, made up of the major cooling components such as the compressor, evaporator and condenser
- A problem with a door seal or gasket
- Only a factory certified service technician can determine the exact cause of a cooling issue.
Common indications of a temperature problem in a Sub-Zero refrigerator
- Warm temperatures in a refrigerator.
- High temperatures reported in refrigerator section
- Why is the refrigerator not cooling or won’t hold set temperature
- Unit does not cool well in warm months or humid, warmer temperatures
- Food spoils before expiration date or food going bad quickly
For any warm temperatures in a Sub-Zero refrigerator, follow these steps:
- Verify the unit has been turned on for at least 24 hours, if not, wait 24 hours for unit to cool properly.
- Clean the condenser if not done in the last 3 months
- Verify there are no error codes or service indicators on the electronic control panel
- Check the set point temperatures for the compartment. On an electronic control panel 38° is the factory setting. For a dial control, set the dial between 4 – 6, 1 is warmest, 10 is coldest.
- Correct or remove anything obstructing the door from closing
- Ensure the door was not left ajar for a period of time.
- Turn the door ajar alarm on if not being used to ensure door is closing all the way.
- New groceries or warm food will raise temperatures for a period of time
Wait 24 hours for the unit to return to normal temperatures after correcting any or all of the above.
