This one is Frigidaire’s, and it appears on the refrigerator that Frigidaire built and Sears sold under the Kenmore badge. Four different manufacturers built refrigerators under this badge, and several of them use an F with a number for unrelated conditions. That is the single most convincing way to reach the wrong component. ### What the appliance is telling you Sabbath mode — Frigidaire's wording is that it makes the appliance function with minimum power to conform with religious observance. This one is an indicator rather than an error. It is published in the same table as genuine problems, and treating it as one is how a working appliance gets a service call. ### Which Kenmore models can raise it The Kenmore refrigerator whose model number begins 253 — the three digits before the period on the rating plate. Those digits are Frigidaire’s, which is why Frigidaire’s table is the one that applies to SB and no other manufacturer’s does. ### The other ways it may be written The same condition is published under more than one label, because it has been carried across generations of the appliance and because a segment display draws some characters oddly: **Sb, SB SB**. They are the same finding and they lead to the same place. ### Worth trying yourself, in this order - Follow the manual's exit procedure. - It is easy to enter by accident on some panels, and the cabinet behaves oddly rather than obviously wrongly while it is on. ### Where this usually goes The job this most often becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. A Kenmore refrigerator in this humidity hands its defrost circuit more work than it was sized for, and in a Miami kitchen a floor-level condenser blocks well ahead of any published interval. Photograph the display before you cut the power: a reset clears SB, and on a Kenmore the characters plus three digits off the plate are most of the diagnosis. ### Where this meaning came from Frigidaire’s own documentation: *Refrigerator Error Codes and Alarms, Frigidaire owner support*. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer’s document instead.
