Hotpoint Cooktop Error Code F07

F07 indicates a fault with the NTC temperature sensor on the large induction hotplate, detected through the ISI UART 2 board at connector CN 04. The code has three subcodes: a shorted NTC sensor, an open-circuit NTC sensor, or the large hotplate not being detected as connected. The cooktop disables the affected zone until the fault is resolved.

You should not continue using the large induction zone while F07 is active. The error indicates the cooktop cannot reliably monitor the temperature of that burner, which means overheating protection for that zone is compromised. Other zones may still function normally, but the faulted zone should remain unused until the fault is diagnosed and repaired.

Repair costs vary depending on the fault. If only the connector needs cleaning and reseating, the cost is minimal and may just involve a service call fee, typically in the range of $75 to $150. If the NTC thermistor or inductor coil assembly requires replacement, parts and labor combined can range from $150 to $400 or more depending on part availability and your location.

Some causes of F07 are accessible to a confident DIYer, particularly checking that the connector at CN 04 is properly seated and that contacts are clean. However, testing the NTC thermistor for correct resistance values and replacing internal components requires disassembling the cooktop, which carries electrical risk. If you are not comfortable working inside appliances, a qualified technician is the safer choice.

Resetting the cooktop by switching it off at the breaker and restoring power may temporarily clear the display, but the error will return if the underlying fault is still present. A reset does not repair a failed NTC thermistor, a loose connector, or a disconnected inductor. Proper diagnosis of the root cause is needed for a lasting fix.
