Dacor Wall Oven U35 Error Code

The display reads U35 on an upper or single Dacor wall oven and L35 on a lower oven. Either one means temperature probe 3 is shorted. The service manual behind this entry covers 27-inch and 30-inch single and double ovens with a touch-glass control, without naming a series.

What a shorted probe 3 means

The control saw a probe 3 reading at the low end of its range. The manual points to a poor connection at the board or in the harness, a bad probe, or a bad wire in the harness. If the low reading holds for 60 seconds, the control treats it as a fatal error.

Cooking and cleaning

Both stay available because probe 1 is the primary probe, although the manual notes possible effects on temperature. Keep an eye on results; the oven may run slightly hotter or cooler than normal.

Next step

Call for service. The manual has a technician verify the relay board connections and the probe at its connector, then secure the connection or replace the probe or harness.

Other probe codes to compare

• U34 / L34 – probe 3 open
• U33 / L33 – probe 2 shorted
• U31 / L31 – probe 1 shorted (RTD shorted)
