Possible Causes
Shorted NTC sensor, Sensor wires shorted to chassis, Sensor incorrectly positioned causing overheating, Failed control board sensor circuit
How to Fix / Troubleshooting
Safety: Turn off power at the breaker before inspection.
- Allow cooling: Let the hob cool completely, then test again. If E2 appears immediately, suspect a sensor fault.
- Inspect sensor and wiring: Access the underside and check that the NTC sensor is correctly clipped to the heat sink, not wedged between components. Look for crushed or bare wires touching metal.
- Measure resistance: Use a multimeter to check the NTC resistance at room temperature. A very low resistance (near 0 Ω) indicates a shorted sensor.
Repair: Replace the NTC sensor if shorted. If the sensor tests normal, the control board may be misreading and require replacement.
