Kenmore Microwave Error Code SF

The SF code on a Kenmore microwave stands for Sabbath mode failure. It appears when a power interruption occurs while the microwave was running in Sabbath mode, causing the unit to lose its saved settings. The microwave will not automatically restart with the original Sabbath mode configuration after power is restored. The code is informational and does not indicate a hardware malfunction.

Yes, the SF code does not indicate a safety hazard or a damaged component. The microwave is fully functional and safe to operate. The code simply means Sabbath mode settings were lost and need to be re-entered. Standard cooking functions are not affected by this alert.

In most cases, no repair cost is involved because the SF code is caused by a power interruption rather than a faulty component. Re-entering Sabbath mode settings yourself costs nothing. If the code is caused by a failing control board, replacement part and labor costs can range from roughly 100 to 300 dollars or more depending on the model and service provider. It is worth confirming the root cause before committing to a repair.

To clear the SF code, simply re-enter the Sabbath mode settings manually after power has been fully restored to the unit. There is no repair needed in most cases, as the error is caused by the control board losing its active settings during a power interruption. Once Sabbath mode is reconfigured, the code should no longer display. If the code returns without any power interruption, consult a technician to evaluate the control board.

A basic reset, such as unplugging the unit for a minute and plugging it back in, will clear the displayed code but will not restore the Sabbath mode settings. You will still need to manually re-enter those settings afterward. If the SF code reappears after each power cycle without any outage occurring, there may be an issue with the control board that requires further diagnosis.
