What Does Error F1 Mean?

The Daewoo refrigerator F1 error indicates a malfunction with the freezer temperature sensor (F-sensor), often due to an open or short circuit. This can lead to erratic temperature readings and affect the cooling performance of both the fridge and freezer compartments. When the F1 code appears, it may cause the refrigerator to stop cooling effectively or enter a fault mode, signaling a need for immediate attention.

Common Symptoms:

  • Error code F1 displayed on control panel
  • Refrigerator/freezer may stop cooling properly or enter fault mode
  • Sensor disconnect or short condition detected by control board

Possible Causes

  • Freezer temperature sensor open circuit or short circuit (high)

How to Fix Error F1

DIY Fix Basic checks for F1 error

  1. Unplug the refrigerator from power for at least 5 minutes and plug back in to reset any transient faults.
  2. Ensure the refrigerator is level and doors are closing properly (poor door seal can affect sensor readings).

Technician Only Diagnose and repair F‑sensor issue

  1. Disconnect power to the refrigerator.
  2. Access the main control board and locate the freezer temperature sensor wiring.
  3. Inspect the F‑sensor connector and wiring for damage, corrosion, or loose terminals.
  4. Measure sensor resistance with a multimeter; replace if open or shorted.
  5. If wiring and sensor are normal but F1 persists, inspect/replace the control board input for the sensor.
  6. Reassemble and test.
  7. Verify error no longer appears and cooling is restored.

Parts needed: Freezer temperature sensor, Control board connectors/cables

🛑 When to Call a Pro:
  • If you are not comfortable working with electrical components
