Kenmore codesKenmore range codes

Sabbath mode failure indicator displayed after a power failure or interruption occurred during Sabbath/Holiday mode; the appliance shut off and did not return to original bake settings.

First step from the service manual

After a power failure, the food may be safely removed from the oven while still in the Sabbath mode.

What SF means on a Kenmore range

The SF error code on a Kenmore range indicates a Sabbath mode failure caused by a power interruption while the Sabbath feature was active. The control board detected the loss of power during this specific operating mode and responded by shutting the oven off completely. Per Sabbath mode design, the oven will not restart automatically after this interruption, which is why SF appears and the unit remains off. No component failure is indicated; this is a control state flag, not a hardware fault.

For homeowners: Sabbath mode is a special setting that allows observant Jewish households to use the oven during the Sabbath or holidays within religious guidelines. If the power went out or was briefly interrupted while this mode was running, your Kenmore range shut itself off and displayed SF to let you know it cannot resume on its own. This is intentional behavior, not a sign that something is broken. Your oven is not damaged.

Once Sabbath observance is complete, you can clear the SF code by pressing and holding both the Cook Time and Delay Start keys simultaneously for at least 3 seconds. SF will disappear from the display and normal oven operation will be restored. No parts replacement or service call is required in the vast majority of cases.

Common causes of SF

  1. 01

    Power outage or interruption during active Sabbath mode

    Wiring / connection

    The most common trigger for SF is a power interruption, even a brief one, while Sabbath mode was running. The control board logs this event, shuts the oven off, and displays SF because Sabbath mode prohibits automatic restart.

  2. 02

    Tripped circuit breaker or blown fuse

    Wiring / connection

    A tripped breaker or blown fuse on the range circuit can cut power momentarily or fully, producing the same result as a power outage while Sabbath mode is active. Resetting the breaker or replacing the fuse restores power, but the SF code will still need to be cleared manually.

  3. 03

    Loose or intermittent power supply connection

    Wiring / connection

    A loose terminal block connection or a partially seated power cord can cause brief voltage drops that the control board interprets as a power failure. If SF recurs repeatedly without an obvious outage, inspect the power cord connections at the terminal block on the back of the range.

  4. 04

    Faulty control board failing to retain mode state

    Part replacement

    In rare cases, a failing control board may drop the Sabbath mode state during normal operation even without a true power interruption, triggering SF. If the error returns consistently after being cleared and no power issues exist, the control board may need replacement.

Frequently asked questions about SF

What does SF mean on a Kenmore range?
SF stands for Sabbath failure. It means a power interruption occurred while the oven's Sabbath mode was active. The control board shut the oven off and will not allow it to restart automatically. This is expected behavior built into Sabbath mode, not a sign of a broken component.
How do I fix SF on my Kenmore range?
After your Sabbath observance is complete, press and hold both the Cook Time and Delay Start keys at the same time for at least 3 seconds. The SF code will clear from the display and the oven will return to normal operation. No tools or parts are needed.
Is it safe to use my Kenmore range while SF is showing?
The oven is off when SF is displayed and will not heat, so there is no immediate safety hazard. Food can be safely removed from the oven. The range's surface burners may still function depending on the model, but the oven will not operate until SF is cleared using the Cook Time and Delay Start key combination.
How much does it cost to fix the SF error on a Kenmore range?
In most cases, fixing SF costs nothing. The code clears by pressing and holding Cook Time and Delay Start simultaneously for 3 seconds, which requires no parts or service. If the error keeps returning despite no power outages, a faulty control board could be the cause; a replacement control board for a Kenmore range typically costs between $100 and $250 for the part, plus labor if you hire a technician.
Why does SF keep coming back on my Kenmore range after I clear it?
If SF reappears repeatedly, first check the range's circuit breaker and the power cord connections at the terminal block on the back of the unit for any looseness or corrosion causing intermittent power drops. If the wiring and breaker are sound and the code still recurs without any power interruption, the control board may be failing and should be inspected or replaced.
