Dacor Oven Error Code U35

U35 indicates that the upper or single oven temperature probe 3 has registered a shorted circuit condition. The relay board's analog-to-digital converter detected a value of 0x0010 or lower for 60 continuous seconds, which is outside the normal range for any valid oven temperature. The oven displays this code to prevent operation under conditions where accurate temperature measurement is not possible.

No. The U35 code means the oven cannot reliably read the cavity temperature, so the control system cannot regulate heat correctly. Operating the oven in this condition creates a risk of overheating. The oven should remain off until the probe, harness, or connector issue is diagnosed and corrected.

Repair costs depend on which component has failed. A replacement temperature probe typically falls in the range of $30 to $100 for the part, while a wiring harness can range from $40 to $150 depending on the model. Relay board replacement, if required, is generally the most expensive option and can range from $150 to $400 or more. Adding professional labor costs will increase these estimates, generally by $75 to $150 per hour depending on your area.

Some causes of U35 can be addressed without professional help, such as reseating the probe connector at the relay board or visually inspecting the harness for obvious damage. However, if the probe itself has failed or the harness needs replacement, those repairs involve working near high-voltage components inside the oven and require comfort with appliance disassembly. If you are unsure, contacting a qualified appliance technician is the safer choice.

A power reset may temporarily clear the code from the display, but U35 will return if the underlying short circuit condition is still present at the probe or harness. Because the fault must persist for 60 continuous seconds before triggering, it may not reappear immediately after a reset, but the root cause must be repaired for the code to stay clear.
