The short answer
For 3d31 the published meaning is that the location varies by model. In practice that makes this a code to have read against your own model line rather than against a general list, because the same characters point at different hardware on different builds.

What you see alongside the code
- The oven refuses to start or abandons a cycle — The control stops on a failed check regardless of which component raised it.
- The code returns after every reset — A persistent condition rather than a corrupted cycle, which is the usual presentation.
- The code appeared after a power event — Worth noting because it makes a single clean reset worth doing before anything else.
- NEAR MISS - a different code is also displayed — Where two codes show, the other one is usually the more specific and the better starting point.
Causes in likelihood order
- A component whose identity depends on the model build — Ranked first because it is the honest answer: the code names a position, and the position differs across the line.
- The wiring to that component — Whatever the component turns out to be, its harness is in front of it and fails more often.
- A corrupted control state after a power interruption — The one cause an owner can clear, and the reason a single proper reset is worth doing before the model is looked up.
Check in this order, and why
- Record the exact characters displayed — With a code whose meaning depends on the model, the exact display is the only thing that is certainly yours.
- Find the model and serial plate — The model number is what turns this code into a component name. Nothing else does.
- Do one complete power-down — It clears the single cause an owner can clear, and its failure narrows the field.
The owner-safe procedure
- Write down the code exactly as shown — Characters, spacing and case. On a model-dependent code this is the one detail that cannot be reconstructed later.
About 3 min
- Photograph the model and serial plate — Usually on the frame behind the door or along a drawer edge. A photograph avoids transcription mistakes.
About 8 min
- Switch off at the breaker for several minutes, then restore — One proper reset. If the code clears, it was a corrupted cycle and nothing more.

Safety
Switch off at the breaker before any panel comes off - a capacitor can hold a charge after the power is off. Do not work toward a component identified from a similar code on another model: on this code that is a guess, and a guess with a meter on live terminals is the wrong kind of guess. Put every screw you remove in one place. A fastener left in the base of a cabinet is a rattle at best and a short at worst.
When this is a service call
This goes to a technician early, and unusually that is the efficient choice rather than a cautious one. Without the model-specific documentation there is nothing to check; with it the diagnosis is ordinary. Give the exact code and the model number when booking so the right parts come on the first visit. Ask whether the diagnosis is chargeable separately from the repair. On this class of fault the measuring is most of the work.

What this page does not cover
This page is generalized information about the code rather than about one appliance. It is written for 3d31 as the KitchenAid oven code list documents it across the brand rather than for one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer and is linked from the code index for this appliance. The codes listed beside it in the table above carry the same documented meaning on this platform and are covered on their own pages, so check the characters on your display carefully before acting on this one.
