Air fryer stops heating and displays E2 during preheat or cooking.

Safety first: Disconnect the appliance from power and allow it to cool fully before inspection.

• Visual inspection: Access the cooking chamber sensor by removing the rear/top cover. Inspect the NTC sensor body and wiring for signs of melting, charring, or moisture contamination.
• Check for shorts: With a multimeter, measure resistance across the sensor leads at room temperature. A reading near 0 Ω indicates a shorted sensor. Also check each lead to the metal chassis; there should be no continuity.
• Dry and clean: If the sensor area is greasy or damp (from steam or cleaning), gently clean with a dry cloth and allow to air dry thoroughly. Do not immerse the sensor head in water.
• Replace sensor if needed: If resistance is near zero or unstable, replace the NTC temperature sensor probe with a compatible Gorenje part.
• Board evaluation: If a known-good sensor still triggers E2, the main control PCB may be misreading the sensor and should be replaced by a qualified technician.
