Possible Causes
Open or shorted NTC sensor on coil, Damaged sensor wiring harness, Faulty power module sensor input, Overheating due to blocked ventilation
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker and allow the cooktop to cool.
- Check ventilation: Ensure underside ventilation is not blocked and that the cooling fan operates normally.
- Inspect sensor wiring (advanced): Remove the glass top and locate the temperature sensor (NTC) attached to the affected induction coil. Check for loose or broken wires and reseat connectors.
- Test sensor: Using a multimeter, measure the resistance of the NTC at room temperature and compare to Bosch specifications. Replace the sensor if out of range.
- Replace module if needed: If the sensor and wiring are good, the power module input circuit may be defective and require replacement.
