How Do I Know the Wolf Oven Temperature Sensor Has Failed?

A probe tells you the cavity is wrong; it cannot tell you which part is lying. That is settled at the harness with a meter across the sensor leads, read cold, read again warm, and compared against the table for that model rather than against a number somebody remembers.

Two unrelated faults reach us with the same description. A seal that has gone hard along the top edge lets the cavity shed heat the board cannot see, so it settles under the setpoint and stays there. A bake element that has failed leaves the cavity climbing on whatever else is still live, which reads as never arriving rather than as arriving in the wrong place. The sensor is condemned on a reading, never on a symptom.
