'HE' displayed steadily - Temperature sensor defect

What does HE mean?

The cooktop display shows a steady 'HE' even when the cooking zone is cold and switched off, indicating a defect in the temperature sensor.

• Defective coil RTD (Resistance Temperature Detector) sensor (resistance not approximately 1K ohms at room temperature)
• Defective generator circuit board

Click steps to track your progress.

1. 1

   Test the coil RTD; it should have a resistance of approximately 1K ohms at room temperature. Replace the coil if the resistance is incorrect.

2. 2

   If the coil resistance is good and connections are secure, replace the generator circuit board.

3. 3

   If the problem persists, contact a qualified technician for assistance.
