Error 1 and 7 - Ice maker sensor and Refrigerator defrost error

Samsung · Refrigerators

What does 1 and 7 mean?

Running the self-diagnostics reveals two error codes: '1' for an ice maker sensor issue and '7' for a Refrigerator defrost error. These codes point to problems with both the ice production system and the defrosting function in the fresh food section.

Common Causes

  • Faulty ice maker sensor or wiring
  • Defrost system malfunction in the Refrigerator section (heater, sensor, or control)
  • Ice buildup affecting either the ice maker or the Refrigerator defrost cycle

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Unplug the Refrigerator and manually defrost it completely for 24-48 hours to clear any ice buildup in both sections.

  2. 2

    After defrosting, carefully inspect the ice maker for any obstructions or frozen components.

  3. 3

    Check the Refrigerator's back panel (often behind crisper drawers) for ice buildup related to the defrost system.

  4. 4

    If codes persist, a technician may need to test the ice maker sensor and Refrigerator defrost system components for faults.
