What 03
actually means.
Err 03 on an older Wolf dual-fuel stove means the control sees an open circuit on its RTD oven sensor, so it cannot tell how hot the oven is. Owners often notice the cooling fan running on and on at the same time.

What to do when 03 shows on the stoveKind of codeTemperature sensor
The thin probe on the back wall of the oven sent the stove a reading it would not trust, or one that kept climbing past the setting. A loose plug behind the stove or a probe knocked against the racks is ruled out before the sensor or the board is replaced. If the oven keeps getting hotter with the controls turned off, switch the stove off at its breaker first.

Before you book,
in this order.
Each step comes from Wolf's own guidance for 03 on its stoves. Follow it to the end: the last card says whether this is a visit.
Shut the oven off and wait for it to cool.
Switch the breaker to the stove off for 30 seconds, then back on, and try a short bake.
If Err 03 or the nonstop fan returns, book a visit for the sensor and its connector.

What not to do
The fan that keeps running is a reaction to Err 03, not a separate fan problem. Replacing the fan will not stop it while the sensor still reads open.
