Possible Causes

Failed NTC sensor on zone, Broken sensor wiring, Loose connector on control board, Faulty sensor input on PCB

Safety: Internal sensors are not user‑serviceable. Do not open the appliance unless qualified.

Power reset: Turn off the appliance at the breaker for 10 minutes, then restore power and test.
Identify affected zone: Try each zone. The one that triggers F4 likely has the faulty sensor.
Professional repair: A technician will access the underside of the cooktop, test the NTC sensor and wiring, and replace the sensor or control board as required.
