# Frigidaire-built Kenmore range error code F31

### Whose code this actually is

Kenmore did not write F31, because Kenmore has never built an appliance. This one is Frigidaire’s, and it appears on the range that Frigidaire built and Sears sold under the Kenmore badge. Ranges under this badge came from Frigidaire, GE and Roper, and one of those three publishes no code documentation at all — so even knowing a range is not enough. The prefix is.

### What it means

Frigidaire's own label: shorted probe. The other half of the same story as F30.

### Which Kenmore models can raise it

The Kenmore range whose model number begins 790 — 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 F31 and no other manufacturer’s does.

### What happens next

- Thirty seconds off the breaker.
- A shorted sensor typically makes the oven behave as though it is already hot, so it never heats.

### Where this usually goes

The job this most often becomes is [oven sensor and calibration service](/services/oven-sensor-and-calibration-service/), and that page carries a starting figure and the reasons that move it. A Kenmore range in a South Florida kitchen is usually freestanding rather than built in, which keeps the access short and means most of these end in one visit. Photograph the display before you cut the power: a reset clears F31, 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: *Ranges — Error Code Guide, Frigidaire owner support*. Kenmore publishes none of its own, which is why every entry on this site names the manufacturer’s document instead.
