# Wolf built-in oven error code 0A31

### What this one means

A switching device is passing current when the control has told it to stop, on a built-in oven, where every part named here sits behind trim that is screwed into the cabinetry rather than behind a panel that slides out. It is a code the manufacturer publishes for this appliance, not one we have worked out — and it is decoded here rather than left as three characters on a display.

### The other ways your machine may say it

The same condition is published under more than one label on this equipment, because the boards report it differently depending on which one saw it:

- **0A31, 0A20** — the same condition under both labels

### What the code covers

A published cause names a circuit rather than a component, which is the single most useful thing to know before ordering a part. This one covers:

- A relay welded closed by years of switching a heavy load
- A triac that has failed short
- The element circuit that relay or triac feeds
- Upper left convection fan triac shorted

### Worth doing before you call

- Note which cavity it is on a double oven — the code says upper or lower and that is half the diagnosis
- Switch the appliance off at the breaker if it is heating with nothing selected

### Then what

A stuck relay is the one error in this archive that can heat with nothing asked of it, so it is a breaker-off condition rather than a wait-and-see one. The board carrying it is a replacement part.

This code is published for built-in ovens & steam ovens. The [full list of codes](https://wolfmiami.support/error-codes/) has the rest of them, searchable, including the labels older and newer machines use for the same conditions.
