What F-25 means on a KitchenAid cooktop

The F-25 error code on a KitchenAid cooktop indicates a stuck or non-responsive cooling fan on the power control board. These cooktops use dedicated cooling fans to manage heat generated by the power electronics. The error is directional: if the code appears on the left side of the display, the fault is with the left-side fan; if it appears on the right, the right-side fan is the source of the problem. The designation "Type 2" distinguishes this from similar fan fault codes that apply to different configurations or control board generations.

The cooling fan on the power control board serves a critical thermal management function. When the control board detects that a fan is not spinning as expected, it triggers F-25 to protect the power electronics from heat damage. A "stuck" fan means the control circuit is not receiving confirmation that the fan is running, which can result from a physical obstruction, a failed fan motor, a wiring fault, or a loose connector interrupting the signal between the fan and the board.

Diagnosis begins by disconnecting power to the cooktop and verifying that the cooling fan connector is firmly seated. Connector looseness is a frequent cause of this fault and requires no parts replacement. If the connector is secure, the fan itself should be inspected for debris obstructions and tested for motor continuity. Persistent faults after connector inspection typically point to a failed fan motor or a fault on the power control board itself.

Common causes of F-25

  1. 01

    Loose or disconnected fan connector

    Wiring / connection

    The cooling fan connector may have vibrated loose from the power control board or the fan itself. This is the first thing to check after disconnecting power, as reseating the connector can clear the fault without any parts replacement.

  2. 02

    Debris or obstruction blocking the fan blade

    Wiring / connection

    Grease, dust buildup, or a foreign object can physically block the fan from spinning. Inspect the fan blade for any material that may have accumulated and is preventing rotation.

  3. 03

    Failed cooling fan motor

    Part replacement

    The fan motor itself may have failed electrically or mechanically. If the connector is secure and no obstruction is present but the fan does not spin freely or shows no continuity, the fan assembly will need to be replaced.

  4. 04

    Damaged wiring harness between fan and control board

    Part replacement

    The wiring between the fan and the power control board can develop a break or short, causing the board to read the fan as non-functional. Inspect the harness for visible damage, pinching, or burn marks.

  5. 05

    Faulty power control board

    Part replacement

    If the fan motor and wiring check out correctly, the power control board itself may be unable to drive or detect the fan signal. A failed board will require replacement to resolve the fault.

Frequently asked questions about F-25

What does F-25 mean on a KitchenAid cooktop?
F-25 indicates a stuck or non-responsive cooling fan on the power control board. These cooktops have separate fans for the left and right sides of the board, and the side of the display where the code appears identifies which fan has the fault. The error is a protective measure to prevent the power electronics from overheating.
Can I fix an F-25 error myself, or do I need a technician?
Some causes of F-25 are DIY-friendly. After disconnecting power, checking that the cooling fan connector is firmly plugged in costs nothing and may resolve the fault. Clearing debris from the fan blade is also a straightforward task. However, replacing a fan motor or power control board involves disassembling the cooktop and working near high-voltage components, which is generally better suited to a qualified technician.
Is it safe to keep using my KitchenAid cooktop while F-25 is showing?
It is not recommended to continue operating the cooktop with an active F-25 fault. The cooling fan exists to protect the power control board electronics from heat damage. Running the cooktop without proper cooling in place risks damaging the control board, which can turn a relatively minor repair into a much more expensive one.
Will resetting the cooktop clear the F-25 error?
A power reset by disconnecting the unit may temporarily clear the display, but the code will return if the underlying fault is not corrected. If the fan connector was simply loose, reseating it before restoring power may resolve the issue permanently. If the fan motor or control board is faulty, the error will reappear during operation.
How much does it cost to repair an F-25 error on a KitchenAid cooktop?
Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, there is no parts cost and only minimal labor if a technician is called. Replacing a cooling fan motor typically runs in the range of $50 to $150 for parts, plus labor. A power control board replacement is the most expensive scenario, with parts costs generally ranging from $150 to $400 or more depending on the model, plus labor charges.
