Kenmore Range Error Code SF

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.

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.

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.

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.

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.
