# Wolf dual fuel range error code KEY COMM

### What this one means

Two boards inside the appliance have stopped hearing each other, 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:

- The ribbon or harness between the control head and the board that switches the loads
- Either board's own transceiver
- A connector that has worked loose behind a fascia that gets hot every day
- Failure between the oven controller and the control panel assembly

### Worth doing before you call

- Check whether the burners still light — gas and electric fail independently here
- Switch the breaker off for thirty seconds and back on, and see whether the display returns

### Then what

A network error is a wiring question before it is a parts question, and the wiring lives behind the control panel. It is not a panel a homeowner should have off with the appliance live.

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.
