Induction cooktop displays F23 and shuts down affected zone

Safety first: Turn off power at the breaker. Induction components can be hazardous; only proceed if you are comfortable with electrical testing.

• Cool down: Allow the cooktop to cool completely, then retry the zone. If F23 returns immediately, suspect a sensor or board issue.
• Access coil: Remove the cooktop from the counter or open the range top. Locate the affected induction coil and its small temperature sensor (NTC) attached to the coil.
• Inspect sensor wiring: Check for broken, pinched, or burned wires from the sensor to the power module. Reseat the connector.
• Test sensor: With the sensor disconnected, measure resistance at room temperature (typically in the tens of kΩ; refer to Café service data if available). An open or 0 Ω reading indicates a bad sensor.
• Replace components: Replace the induction coil temperature sensor if defective. If the sensor and wiring are good, replace the induction power module.
