Refrigerator compartment is too warm while the compressor runs almost continuously; error E1 shown on display.

Safety first: Unplug the Gorenje refrigerator from the mains before removing any panels or touching wiring. Do not work on live circuits.

Steps to check and address E1:

• Power reset: Disconnect power for 5–10 minutes, then reconnect. If E1 returns after a few minutes, continue with diagnosis.
• Locate the fridge NTC sensor: It is usually clipped to the rear wall of the fresh-food compartment, behind a small plastic cover or inside the air duct near the light housing.
• Inspect the sensor and wiring: Remove the cover, visually check for corrosion, broken insulation, or a loose plug. Reseat the connector firmly.
• Measure resistance: With the unit unplugged, disconnect the sensor from the harness and measure its resistance with a multimeter. At about 25°C, most Gorenje NTC sensors read roughly 4–10 kΩ (check your model’s service sheet). If the reading is open (∞), shorted (≈0 Ω), or far outside spec, the sensor is faulty.
• Check continuity to the control board: If the sensor tests OK, check the harness from the sensor to the main PCB (usually behind the rear service panel or top control housing). Look for pinched or cut wires and test continuity on each conductor.
• Replace the sensor if needed: Order a compatible Gorenje refrigerator compartment NTC sensor by model number. Clip the new sensor in the same position, route the wires as originally, and reconnect.
• Reassemble and test: Refit covers, restore power, and monitor the display. The E1 code should clear automatically after a short run period if the fault is resolved.

When to call a technician: If the sensor and wiring are good, the main control board may be defective and should be diagnosed and replaced by a qualified technician.
