What F41 means on a Kenmore range

The F41 error code on a Kenmore range indicates a cooktop lockout fault. This error is generated when the Electronic Oven Control (EOC) detects a problem in the communication or functionality of the cooktop lockout system. The cooktop lockout feature is controlled by a dedicated Cooktop Lockout Control Board, which interfaces with the EOC to prevent burner operation under certain conditions. When the EOC cannot establish proper communication with this board, or when it receives an unexpected signal, it triggers the F41 fault and disables cooktop operation as a safety precaution.

The most common trigger for this fault is a wiring issue between the Cooktop Lockout Control Board and the EOC. Loose connectors, damaged wire harnesses, or corroded terminals can interrupt the signal path and cause the EOC to register a lockout fault even when the physical lockout board itself is functioning correctly. This is why wiring inspection is the required first diagnostic step before replacing any components.

If the wiring is found to be intact and properly connected, the Cooktop Lockout Control Board itself is the next likely point of failure. A faulty board may send incorrect signals or no signal at all to the EOC. If replacing the Cooktop Lockout Control Board does not resolve the fault, the EOC itself may be defective and is the final component to consider replacing. Component failures in either board can be caused by electrical surges, heat exposure, or general component degradation over time.

Common causes of F41

  1. 01

    Wiring or connector fault

    Wiring / connection

    Loose, damaged, or corroded wiring between the Cooktop Lockout Control Board and the EOC is the most frequent cause of F41. Inspect all connectors and wire harnesses in the circuit for signs of damage, burning, or poor contact.

  2. 02

    Failed Cooktop Lockout Control Board

    Part replacement

    If wiring checks out, the Cooktop Lockout Control Board itself may have failed and is sending an incorrect or absent signal to the EOC. Replacing this board is the next recommended step after ruling out wiring issues.

  3. 03

    Defective EOC

    Part replacement

    If replacing the Cooktop Lockout Control Board does not clear the fault, the EOC may be malfunctioning and incorrectly reporting a lockout error. This is the least common cause and is addressed only after other components are verified.

  4. 04

    Electrical surge or power event

    Part replacement

    A power surge can damage sensitive components on either the Cooktop Lockout Control Board or the EOC, leading to a persistent F41 code. Check for signs of visible damage such as burnt areas or failed capacitors on either board.

Frequently asked questions about F41

What does F41 mean on a Kenmore range?
The F41 code on a Kenmore range indicates a cooktop lockout error. This means the Electronic Oven Control has detected a fault in the cooktop lockout system, which involves communication between the EOC and the Cooktop Lockout Control Board. The range disables the cooktop as a precaution when this fault is detected. The issue typically originates from faulty wiring, a failed Cooktop Lockout Control Board, or in some cases a defective EOC.
Can I fix the F41 error on my Kenmore range myself?
A knowledgeable DIYer can begin by inspecting the wiring and connectors between the Cooktop Lockout Control Board and the EOC for any visible damage, loose connections, or corrosion. If the wiring appears intact, the next step would be replacing the Cooktop Lockout Control Board, followed by the EOC if the fault persists. Working on internal range components involves exposure to high-voltage circuits, so the appliance should be completely unplugged before any inspection or repair work begins.
Is it safe to use my Kenmore range when the F41 code is displayed?
The F41 fault typically disables the cooktop burners, so stovetop cooking may not be possible while this error is active. The oven function may or may not be affected depending on how the fault presents on your specific model. It is best to avoid using the appliance until the fault is diagnosed and repaired, as the underlying wiring or control board issue should be properly resolved.
Will resetting the range clear the F41 error code?
Resetting the range by unplugging it or cycling the circuit breaker for a few minutes may temporarily clear the F41 code. However, if the underlying cause is a wiring fault or a failed component, the error will return once the range is powered back on. A reset alone is not a repair and should only be used as a first step to confirm whether the fault is persistent.
How much does it cost to repair an F41 error on a Kenmore range?
Repair costs vary depending on which component is at fault. If only a wiring issue is found, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing the Cooktop Lockout Control Board generally costs between $100 and $250 including parts and labor. If the EOC also needs to be replaced, total repair costs can range from $200 to $450 or more depending on the model and local labor rates.
