Sabbath failure

Kenmore codesKenmore oven codes

Sabbath failure — indicates a power failure or interruption occurred while the Sabbath feature was active; the oven has shut off and will not turn back on automatically.

First step from the service manual

Food may be safely removed from the oven. The oven cannot be turned back on until after the Sabbath/Holidays. After observance, press and hold both Cook Time and Delay Start for at least 3 seconds simultaneously to turn the Sabbath feature off.

What SF means on a Kenmore oven

The SF error code on a Kenmore oven stands for Sabbath Failure. It indicates that a power interruption occurred while the oven was operating in Sabbath mode, a special feature designed to allow continuous oven operation over Jewish Sabbath and holiday observances. When the oven loses power during this mode, the control board registers the interruption as a failure condition and locks out further oven operation as a safety measure. The oven will not restart automatically after power is restored.

The Sabbath feature, when active, overrides many of the oven's standard automatic shutoff functions and keeps the appliance running at a set temperature for an extended period. Because a power failure during this window disrupts the controlled, continuous cycle the feature depends on, the control board flags the event and requires manual intervention before normal operation can resume. No cooking functions are available until the error is cleared.

Clearing the SF code requires waiting until the Sabbath or holiday observance has concluded before interacting with the oven controls. At that point, pressing and holding both the Cook Time and Delay Start buttons simultaneously for at least 3 seconds will deactivate the Sabbath feature and clear the error. Once completed, the oven should return to normal standby operation and all cooking functions will become available again.

Common causes of SF

  1. 01

    Power outage during Sabbath mode

    Wiring / connection

    A brief or extended power outage while the oven was in Sabbath mode is the most frequent trigger for this code. Even a momentary interruption is enough for the control board to register the failure condition.

  2. 02

    Tripped circuit breaker

    Wiring / connection

    A tripped breaker on the oven's dedicated circuit will cut power just as a full outage would. Check the breaker panel and reset any tripped breaker before attempting to clear the SF code after observance.

  3. 03

    Loose or intermittent power connection

    Wiring / connection

    A loose connection at the wall outlet, the terminal block, or the power cord can cause intermittent power drops that trigger this error even when the household power supply is stable.

  4. 04

    Voltage fluctuation or brownout

    Wiring / connection

    A significant drop in line voltage, such as during a brownout, can cause the control board to detect a power failure even if the lights in the home stay on. The oven's electronics are sensitive to sustained low-voltage conditions.

  5. 05

    Control board fault

    Part replacement

    In rare cases, an internal fault in the electronic control board can cause it to incorrectly log a power failure event. If the SF code reappears shortly after being cleared under normal power conditions, the control board may need inspection or replacement.

Frequently asked questions about SF

What does SF mean on a Kenmore oven?
SF stands for Sabbath Failure on a Kenmore oven. It means the oven lost power while the Sabbath feature was active, causing the oven to shut off as a safety response. The oven will not restart on its own and requires manual steps to clear the code after the observance period has ended.
How do I fix the SF error code on my Kenmore oven?
After your Sabbath or holiday observance is complete, press and hold both the Cook Time and Delay Start buttons at the same time for at least 3 seconds. This turns off the Sabbath feature and clears the SF error, allowing the oven to return to normal operation. No tools or parts are needed for this process.
Is it safe to leave food in the oven when the SF code appears?
Food can be safely removed from the oven when the SF code is displayed. Since the oven has shut off entirely, it will no longer maintain any temperature, so perishable food should be removed and handled according to standard food safety guidelines. There is no electrical or fire hazard associated with the SF code itself.
Will resetting the oven clear the SF code?
A standard power reset by itself will not clear the SF code or restore oven operation. The correct way to clear it is to press and hold Cook Time and Delay Start simultaneously for at least 3 seconds after your observance concludes. Attempting to bypass the code before the observance ends is not recommended per the feature's intended design.
How much does it cost to repair a Kenmore oven showing an SF code?
In most cases the SF code requires no repair at all, just the button sequence described above, making the cost zero. If the code returns repeatedly under normal power conditions and a control board fault is suspected, control board replacement on a Kenmore oven typically runs between $150 and $400 depending on the model and whether you hire a technician. Checking the power supply and connections first is a good step before spending money on parts.
