Dacor Range, Oven, Cooktop Error Code U32

U32 indicates an open circuit in RTD 2, the temperature sensor for the upper or single oven cavity. The control board is not receiving a valid resistance signal from the sensor, which means it cannot monitor oven temperature. The oven will not operate normally until the sensor circuit is repaired or the sensor is replaced.

No. With U32 active, the oven control cannot accurately monitor the cavity temperature. Continuing to operate the oven in this condition risks overheating the cavity with no temperature feedback to regulate the heating elements. The oven should remain off until the sensor circuit is repaired.

A power reset may temporarily clear the U32 code from the display, but the error will return as soon as the control board checks the RTD 2 circuit again at startup or during operation. The underlying open-circuit condition in the sensor or wiring must be physically corrected for the code to clear permanently.

In some cases, yes. Start by checking all wiring connections between the RTD 2 sensor and the control board, since a loose or corroded connector is a common cause. If you are comfortable using a multimeter to test continuity in the sensor and its wiring, you can diagnose whether the fault is in the wiring harness or the sensor itself. Replacing the sensor is a straightforward repair for someone comfortable working inside an oven cavity.

If only a wiring connector needs reseating or cleaning, there may be no parts cost at all. A replacement RTD temperature sensor typically runs in the range of $30 to $100 depending on the specific Dacor model. If a technician is needed, total repair costs including labor generally fall in the range of $100 to $250, though this varies by region and the extent of the repair.
