Sub-Zero refrigerator crisper drawers are supposed to provide the optimal temperature and humidity levels to preserve produce. But misuse or small glitches can create the need for adjustments. Common problems with the moisture settings in Sub-Zero Crisper drawers include excessive condensation and food freezing. Simple temperature adjustments and cleaning methods can solve the problem.
Understanding Moisture Settings in Sub-Zero Crisper Drawers
Crisper drawers work by maintaining a separate moisture setting than that of the refrigerator to keep fruits and vegetables fresher longer. Before we discuss some common problems with Sub-Zero crisper drawer humidity we’ll review the optimal settings for crisper drawer foods. We’ll also illustrate how to adjust the moisture settings in Sub-Zero crisper drawers for ideal food storage.
What Should I Set My Sub-Zero Crisper Drawer At?
Generally speaking, leafy vegetables that wilt easily are better preserved on a high-humidity setting. Fruits that are prone to rotting do better in a low-humidity environment. For optimal food storage moisture settings in Sub-Zero crisper drawers should have one drawer set on high humidity and another on a low setting.
How Do I Adjust the Moisture Settings in My Sub-Zero Crisper?
The moisture settings in Sub-Zero crisper drawers are easily adjusted by moving the slide on each drawer. Moving the slide lower opens a vent to create a lower humidity environment for fruit. Adjusting it higher closes the vent to make a high humidity environment for vegetables.

Why is There Condensation in My Sub-Zero Refrigerator Crisper?
Excessive moisture in refrigerator crisper drawers indicates an overly humid environment. If you notice this in your Sub-Zero crisper, we suggest lowering the slide to open the drawer vent and allow the moist air to escape. If excessive condensation in Sub-Zero refrigerator drawers continues, follow these troubleshooting steps:
- Make sure the refrigerator door is always closed and open only for short periods of time
- Assess the drawer gasket for leaking, tearing or damage. A damaged gasket requires replacement. Thoroughly cleaning and drying can resolve a leaking gasket.
- Remove the crisper drawer and look for a buildup of ice, water or food debris that may block the drain tube along the back wall. Clear away any debris, ice, or water.
- Ice or water in the refrigerator drain tube can cause excess moisture in the crisper drawer. We suggest referring to your owner’s manual to properly clean and clear the drain tube.
Why is Food Freezing in the Crisper Drawer on My Sub-Zero?
When you find food freezing in crisper drawer there can be a temperature issue or airflow problem. These tips can help pinpoint the complication:
Check your refrigerator temperature settings: if the refrigerator temperature is set above 34°F it may make the crisper drawer fans run excessively. This will create too cold a temperature in the drawer and food may freeze. Make sure your refrigerator is set at 34°F to avoid overuse of the drawer fans.
Keep the refrigerator door closed: this maintains the refrigerator’s temperature and prevents overuse of the crisper drawer fans
Clean the condenser coils: a dirty condenser can lead to airflow problems that create too cold a temperature in the crisper drawer. Generally, the condenser coils can be cleaned by vacuuming them with a brush attachment. We suggest referring to your user manual to confirm the location of the condenser coils and proper cleaning method for your model refrigerator.
