# Wolf dual fuel range error code 0B

### What this one means

The appliance measures its own supply and its own relays on power-up, and that measurement did not complete, on a dual fuel range, which is two appliances on one chassis: gas burners above, an electric oven below, and one control board answering for both. 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:

- An unstable supply during the check
- The board doing the measuring
- A relay that did not answer when it was tested
- Analog to digital error during calibration phase

### What to try yourself

- Check whether the burners still light — gas and electric fail independently here
- Switch the breaker off for thirty seconds and back on so the check runs again

### Then what

A calibration that fails once and passes on the second power-up was a supply event. One that fails every time is the board.

This code is published for ranges. 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.
