Hotpoint Cooktop Error Code F14

F14 indicates that the ISI UART 1 channel (connector CN 03) has detected an excessively high temperature on the large induction coil. The control board monitors coil temperature through a dedicated NTC thermistor, and when the reading exceeds the safe threshold, it triggers F14 and disables the affected zone. The fault can reflect a genuine overtemperature condition or a miscalibrated sensor reporting a false high reading.

No. The cooktop shuts down the large cooking zone specifically to prevent coil damage or a more serious thermal event. Continuing to attempt to use the affected zone while the fault is active is not recommended. The underlying cause, whether a faulty sensor or actual overheating, should be diagnosed and resolved before resuming normal use.

Repair costs vary depending on the root cause. Cleaning blocked vents is essentially free, while replacing an NTC thermistor typically falls in a lower cost range for parts, though labor adds to the total. A cooling fan replacement or coil assembly repair will generally cost more, with parts and labor combined potentially ranging from moderate to significant depending on your region and the technician's rates. Getting a diagnostic assessment first helps narrow down the actual repair needed before committing to a cost.

Some basic checks are within reach for a confident DIYer, such as clearing ventilation blockages and inspecting the CN 03 connector for loose wiring. However, testing NTC thermistor calibration requires a multimeter and knowledge of the expected resistance values, and replacing internal components involves working near high-voltage induction electronics. If you are not comfortable with appliance electrical work, a qualified technician is the safer choice.

A power reset by switching off the cooktop at the circuit breaker for several minutes may temporarily clear the fault display. However, if the NTC thermistor is miscalibrated, the cooling fan is failing, or ventilation is blocked, the error will return during the next cooking session. A reset addresses the symptom but not the underlying cause, so proper diagnosis is still required.
