What Does Error F1 Mean?

The Hisense refrigerator error F1 indicates a fault with the temperature sensor, commonly known as the thermistor, or its wiring connections. This malfunction leads to incorrect temperature readings, causing inadequate cooling in the refrigerator compartment while the freezer may still operate. Symptoms include the F1 code displayed on the control panel, warm temperatures inside the fridge, and inconsistent cooling performance.

Common Symptoms:

  • F1 displayed on control panel
  • Refrigerator compartment not cooling properly despite freezer working
  • Warm temperatures inside fridge section
  • Inconsistent or incorrect temperature readings

Possible Causes

  • Faulty refrigerator temperature sensor (thermistor) (medium)
  • Loose, damaged, or disconnected sensor wiring (medium)

How to Fix Error F1

DIY Fix Basic inspection and reset

  1. Unplug the refrigerator from power for at least 5–10 minutes to attempt a reset.
  2. Ensure doors and drawers are fully closed and door seals are intact.
  3. Check that fridge settings are correct and allow space around the appliance for airflow.

Technician Only Inspect and replace temperature sensor/thermistor

  1. Disconnect power and remove interior panels to access the refrigerator temperature sensor.
  2. Visually inspect the thermistor and associated wiring for damage, corrosion, or poor connection.
  3. Use a multimeter to test the thermistor resistance at known temperatures and compare to specification.
  4. Replace the sensor if readings are out of spec and reassemble.

Parts needed: temperature sensor (thermistor), wiring harness

🛑 When to Call a Pro:
