⚠ What This Means

The refrigerator and/or freezer temperature is higher than the set point. Food may not be as cold as expected.

🔧 How to Fix

  1. Check that the temperature control is set properly on the Control Center (recommended: 38 deg F / 3 deg C for refrigerator, 0 deg F / -18 deg C for freezer).
  2. Clean the condenser area behind the grille to ensure proper heat dissipation.
  3. Check that doors and drawers are fully closed and sealed. Ensure food is not obstructing proper closing.
  4. If a large amount of food was added recently, allow 24 hours for the unit to stabilize to the set temperature.
  5. If the issue persists after these checks, call Sub-Zero Customer Service at 800-222-7820.
