Dacor Range Oven Cooktop Error Code F10

The F10 error code on a Dacor Discovery Range indicates a Clean/Cook Runaway condition, meaning the oven's control board has detected that the cavity temperature is rising beyond expected parameters or behaving erratically in a way that suggests a loss of accurate temperature feedback. The primary culprit in this fault is an intermittent temperature sensor or compromised wiring connections leading to the sensor. When the sensor signal drops out or fluctuates unpredictably, the control board loses its ability to regulate the heating elements correctly, which can cause the oven to overheat or behave erratically during cooking or self-clean cycles.

The temperature sensor itself is a resistance-based component, typically a platinum RTD (resistance temperature detector), whose resistance value changes in a predictable way as the oven cavity heats up. When wiring connections to the sensor become loose or corroded, the control board receives inconsistent resistance readings. This can cause the board to interpret the oven as cooler than it actually is, driving the heating elements harder than necessary and triggering the runaway fault. Intermittent sensor behavior is often the most difficult to diagnose because the fault may not appear consistently.

Diagnosis should begin at the sensor connector points, both at the sensor body located inside the oven cavity and at the control board harness. Inspect for loose pins, heat damage, or oxidation on the terminals. If connections are secure and clean, the sensor itself should be tested for proper resistance values at room temperature and compared against specification. A sensor that reads outside the expected range or fluctuates under light physical manipulation should be replaced.
