# Wolf dual fuel range error code 0122

### What this one means

A switching device is passing current when the control has told it to stop, 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:

- 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
- Drive relay or triac for an element is closed when it should be open

### Worth doing before you call

- Check whether the burners still light — gas and electric fail independently here
- 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 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.
