# Wolf built-in oven error code E38

### What this one means

The appliance lost power in the middle of doing something and stopped where it was, 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.

### 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 cut, a brownout or a surge during a cook or a clean cycle
- A breaker that tripped and was reset
- A cycle that never finished and was never cleared
- Electronics area temperature too high
- Exhaust fan failure
- Power failure during baking process

### What to try yourself

- Note which cavity it is on a double oven — the code says upper or lower and that is half the diagnosis
- Switch the breaker off for thirty seconds and back on
- Start the appliance again and watch whether the code comes back

### Then what

A code that appears once after a storm is history. One that returns on a settled supply is not about the power at all, and the next step is measuring rather than resetting.

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.
