# Wolf built-in oven error code 03

### What this one means

The control asked for heat and did not see the current that should have followed, 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:

- The element itself, open somewhere along its length
- The relay or the wiring feeding it
- A thermal cutout that has opened and not reset
- No Broil Element detected
- No cooling fan detected
- No Left Convect Fan detected
- No Lt Convect Element detected

### 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
- Note whether the oven still heats on other modes — bake, broil and convection use different elements

### Then what

Naming the circuit is what this code does, and it is the useful part: it says which element to test before anything is ordered. Testing it means the back panel off, with the supply isolated.

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.
