What F-37 means on a KitchenAid cooktop

The F-37 error code on a KitchenAid cooktop indicates a fault in the Type 1 temperature sensor circuit. This sensor is a thermistor, a resistive device whose electrical resistance changes predictably with temperature. The control board continuously monitors the resistance value reported by this sensor to regulate cooking surface temperature. When the measured resistance falls outside the expected operating range, the board interprets this as a sensor failure and triggers the F-37 code to prevent uncontrolled heating.

At room temperature, a properly functioning Type 1 temperature sensor should measure between 184,000 ohms and 292,000 ohms. Readings outside this range, whether significantly lower or higher, indicate the thermistor element itself has degraded or failed. An open circuit (infinite resistance) typically means a broken thermistor or severed wiring. A very low resistance reading suggests an internal short within the sensor. Both conditions prevent the control board from accurately tracking surface temperature.

The most reliable first step is to disconnect power to the cooktop before performing any checks, then measure the sensor resistance with a multimeter set to the appropriate ohm range. Also confirm the sensor connector is fully seated at both the sensor and control board ends, as a loose connection can produce intermittent or out-of-range readings that mimic sensor failure. If wiring and connections check out but resistance is out of spec, the thermistor requires replacement.

Common causes of F-37

  1. 01

    Failed temperature sensor (thermistor)

    Part replacement

    The thermistor element inside the sensor has degraded and its resistance no longer falls within the 184,000 to 292,000 ohm range at room temperature. This is the most frequent cause and is confirmed by measuring the sensor with a multimeter.

  2. 02

    Loose or disconnected sensor connector

    Wiring / connection

    The wiring connector at the temperature sensor or control board end has worked loose, causing an intermittent or open circuit. Disconnecting power and firmly reseating both connectors can resolve this without replacing any parts.

  3. 03

    Damaged sensor wiring

    Part replacement

    The wires running between the temperature sensor and the control board may be pinched, burned, or broken, causing an incorrect resistance reading at the board. Visually inspecting the wire harness for heat damage or abrasion will help identify this condition.

  4. 04

    Corroded connector terminals

    Wiring / connection

    Moisture or heat exposure can cause oxidation at the sensor connector terminals, increasing contact resistance and causing the board to read an out-of-range value. Inspecting the terminals for discoloration or buildup and cleaning or replacing the connector can resolve this.

  5. 05

    Faulty control board

    Part replacement

    If the sensor measures correctly within the 184,000 to 292,000 ohm spec and all wiring and connections are intact, the control board itself may have a defective input circuit that cannot accurately read the sensor signal.

Frequently asked questions about F-37

What does F-37 mean on a KitchenAid cooktop?
F-37 indicates that the Type 1 temperature sensor is not functioning correctly. The cooktop's control board monitors the sensor's resistance value and triggers this code when the reading falls outside the expected range. The cooktop disables heating as a safety measure until the sensor issue is resolved.
Can I fix the F-37 error myself, or do I need a technician?
A knowledgeable DIYer can perform the initial diagnostics by disconnecting power and using a multimeter to check the sensor resistance, which should read between 184,000 and 292,000 ohms at room temperature. Reseating a loose connector is also a straightforward fix. Replacing the thermistor or control board involves working with appliance wiring and may be better handled by a qualified technician if you are not comfortable with those repairs.
Is it safe to use my KitchenAid cooktop while the F-37 code is active?
No, you should not attempt to use the cooktop while F-37 is displayed. The error means the control board cannot reliably monitor the cooking surface temperature, which removes a key safety control. Operating the cooktop in this state risks uncontrolled heating and potential damage or hazard.
Will resetting the cooktop clear the F-37 error code?
Disconnecting power briefly may temporarily clear the code, but it will return if the underlying sensor fault still exists. A reset is useful for ruling out a one-time control glitch, but if the temperature sensor resistance is out of range or a wiring fault is present, the code will reappear once power is restored and the board re-checks the sensor.
How much does it cost to repair a KitchenAid cooktop with an F-37 error?
Repair costs depend on which component has failed. A replacement temperature sensor is typically a lower-cost part, while a control board replacement is significantly more expensive. Adding a service call and labor, total repair costs can range from around $100 to $400 or more depending on the specific parts needed and your location.
