KitchenAid codesKitchenAid cooktop codes

The surface cooking area is too hot and has turned off; NTC temperature of the touch control is excessively high (>100°C). If F2 appears, cooking zones 1 and 4 will not work.

First step from the service manual

Remove the pans from the surface cooking area. F2 will disappear when the surface cooking area has cooled down.

What F2 means on a KitchenAid cooktop

The F2 error code on a KitchenAid cooktop indicates that the NTC (Negative Temperature Coefficient) thermistor embedded in the touch control assembly has detected a temperature exceeding 100°C. This sensor monitors the thermal condition of the control electronics, not the cooktop surface itself. When the NTC reading climbs above this threshold, the control board interprets the condition as a safety risk and shuts down cooking zones 1 and 4 to prevent damage to the electronics and reduce heat generation in the affected area.

The NTC thermistor functions by changing its electrical resistance as temperature rises. Under normal operating conditions, the control electronics stay well below the 100°C trigger point. Excessive heat buildup around the touch control can occur when pans are left on high heat for extended periods, when cookware significantly overhangs the zone boundaries, or when the cooktop is used in conditions with inadequate ventilation around the control panel area. The heat radiating from the cooking surface transfers to the control assembly and, if sustained, drives the NTC reading above the fault threshold.

Once F2 is triggered, the cooktop locks out zones 1 and 4 until the NTC temperature drops back to a safe level. Removing pans and allowing the unit to cool is the required first step. If F2 reappears consistently even during normal cooking loads, this may point to a degraded NTC thermistor giving inaccurate high readings, or a fault in the touch control board itself that is failing to process sensor data correctly.

Common causes of F2

  1. 01

    Prolonged high-heat cooking

    Wiring / connection

    Running one or more zones at maximum power for an extended time can radiate enough heat into the control panel area to push the NTC sensor above 100°C. Reducing heat levels or cooking in shorter intervals can prevent recurrence.

  2. 02

    Oversized or overhanging cookware

    Wiring / connection

    Pans that extend beyond the cooking zone boundary concentrate radiated heat toward the control electronics. Using correctly sized cookware matched to each zone reduces thermal stress on the control assembly.

  3. 03

    Poor ventilation around the cooktop

    Wiring / connection

    Blocked airflow beneath or around the cooktop can trap heat near the touch control area, accelerating the temperature rise that triggers F2. Check that the installation clearances are met and that nearby cabinetry is not restricting airflow.

  4. 04

    Faulty NTC thermistor

    Part replacement

    An NTC sensor that has drifted out of calibration or failed can report falsely elevated temperatures even when the cooktop is not actually overheating. This is indicated by F2 appearing quickly during light cooking or immediately after startup.

  5. 05

    Defective touch control board

    Part replacement

    If the control board is misreading or misprocessing the NTC signal, it may trigger F2 incorrectly. This is typically diagnosed after confirming the thermistor itself tests within specification.

Frequently asked questions about F2

What does F2 mean on a KitchenAid cooktop?
F2 means the NTC temperature sensor in the touch control assembly has detected a temperature above 100°C, indicating the control area is overheating. As a safety response, the cooktop automatically disables cooking zones 1 and 4. The code will clear on its own once the unit cools to a safe temperature. Removing pans from the surface and allowing the cooktop to cool is the recommended first step.
Will the F2 error clear on its own, or do I need to reset the cooktop?
F2 is a temperature-based fault that clears automatically once the NTC sensor reading drops back below the trigger threshold. You do not need to perform a manual reset. Simply remove your pans and give the cooktop time to cool, and the error should disappear without any additional steps.
Is it safe to continue using my cooktop while F2 is displayed?
When F2 is active, cooking zones 1 and 4 are already disabled by the control board, so those zones cannot be used regardless. The cooktop is protecting itself from potential heat damage to the electronics. You should stop cooking, allow the unit to cool completely, and investigate whether usage habits or a component fault is causing the repeated overheating before resuming normal operation.
How much does it cost to repair a KitchenAid cooktop showing F2?
If the issue is simply overheating from cooking habits, there is no parts cost involved. If a faulty NTC thermistor is diagnosed, parts and labor typically range from around $100 to $250 depending on the specific model and local labor rates. A failed touch control board is more expensive to replace, with total repair costs often falling in the $200 to $450 range, though this varies by region and service provider.
Why does F2 keep coming back even after the cooktop cools down?
If F2 returns repeatedly during normal cooking, the most likely causes are oversized cookware radiating excess heat toward the controls, inadequate ventilation around the cooktop installation, a degraded NTC thermistor reporting falsely high temperatures, or a failing touch control board. Consistent recurrence despite correct cookware and ventilation warrants a hands-on diagnostic inspection of the NTC sensor and control electronics.
