What Does Error NA Mean?

The Liebherr Refrigerator error code 'nA' indicates a malfunction in the cooling system, often linked to a temperature sensor (NTC) fault or disconnection. This issue may cause the refrigerator to beep, display inconsistent temperatures, or trigger a temperature alarm. If you encounter this error, it is crucial to address it promptly to prevent food spoilage and ensure the unit operates efficiently.

Common Symptoms:

  • Display shows 'nA' or 'NA' message
  • Refrigerator beeping with error display
  • Temperature alarm or unexpected cooling behavior

  • Temperature sensor (NTC) fault or disconnection (medium)

How to Fix Error NA

DIY Fix Basic checks and reset

  1. Ensure the fridge is properly plugged in and power supply stable
  2. Check that doors are fully closed and seals are clean/intact
  3. Try a full power reset: unplug fridge at wall or breaker for ~5 min then restore power and observe display

Technician Only Diagnose temperature sensor and control circuitry

  1. Disconnect power and access the internal temperature sensor (NTC) harness
  2. Visually inspect for loose connectors, damaged wiring, or corrosion
  3. Measure sensor resistance with multimeter at ambient temperature to confirm within expected range
  4. If sensor readings are out of range, replace the faulty NTC sensor
  5. If sensor wiring and NTC are good, check control board inputs and output signals for proper communication
  6. Replace control board only if diagnostics confirm it is failing

Parts needed: NTC temperature sensor, Wiring harness, Control board

🛑 When to Call a Pro:
  • If the error persists after basic power reset and door seal checks
  • If multimeter diagnostics indicate sensor or board faults beyond simple replacement
  • If fridge fails to maintain correct temperature after troubleshooting
