Hotpoint Cooktop Error Code F10

F10 indicates a fault with the heat-sink NTC thermistor on the ISI UART 1 induction generator board, connected at the CN 03 port. Subcode 1 points to a short circuit in the thermistor circuit, while subcode 2 points to an open circuit. The cooktop disables the affected induction zone to prevent damage to the power electronics. Replacing the corresponding induction generator board is the recommended corrective action.

The cooktop disables the affected induction zone when F10 is active, so that burner will not operate. Other zones may continue to function, but it is not advisable to use the cooktop for extended cooking sessions while a fault is active. The underlying fault involves a temperature protection circuit, so continued use without repair could risk undetected overheating of the generator electronics.

Repair costs vary depending on the model and whether a technician is involved. An induction generator board replacement typically ranges from around $150 to $400 or more, including the part and labor. If the fault turns out to be a wiring or connector issue, the cost may be significantly lower. Getting a diagnostic service call before committing to parts replacement is advisable to confirm the root cause.

A knowledgeable DIYer can start by inspecting the CN 03 wiring connector for loose connections, damage, or contamination, as these checks require no special tools beyond basic safety precautions. However, replacing the induction generator board involves working with high-voltage electronics and requires proper discharge procedures and component handling skills. If you are not experienced with induction cooktop internals, a qualified technician should perform the board replacement.

A power reset by switching off the circuit breaker for 30 to 60 seconds may temporarily clear the display, but the fault will return if the underlying cause is not corrected. Because F10 is tied to a hardware failure in the NTC thermistor circuit or its wiring, the error will reappear as soon as the cooktop attempts to operate that generator channel. A reset alone is not a repair.
