# Wolf knob turning with nothing happening

### The fastest diagnosis is the code

Pull the knob off and turn the shaft with pliers, gently. If the appliance responds, the knob is the whole problem and it is an inexpensive part.

### Two minutes, three answers

Pull the knob off and turn the shaft. If the appliance obeys, buy a knob. If the shaft spins without resistance, the shaft or the switch behind it is the answer. If the shaft is stiff, it is a valve. Almost nobody needs a technician to work out which, and this page exists to say so.

The knob itself

The insert that grips the shaft splits with heat and age. Ordered to the model — shafts and printed graduations changed between generations.

Turning without carrying the switch with it. Less common, and it is the middle of the three prices.

The selector switch behind it

This maker publishes mode and temperature selector conditions separately, per cavity, so a switch is named rather than guessed at.

A gas valve that has seized

On a burner knob rather than an oven one. Stiff long before it stops, which is the warning worth acting on.

Knob off, shaft turned

The whole diagnosis in one step, and it costs nothing.

Compare with the others

A knob that has become stiff while its neighbors are smooth is a valve rather than a knob.

Look inside the knob

A split collar is visible the moment it is off.

Note any code

A selector input condition on the display turns this into a named repair immediately.

Knob, shaft or the switch behind it

What it usually means

A knob spinning with no effect

A cracked or discolored knob

A selector that does nothing at any setting
