Dacor Wall Oven U30 / L30 Error Code

U30 is the upper or single oven and L30 is the lower oven. Either one, shown as U30 TEMP SENSOR or L30 TEMP SENSOR, means temperature probe 1 reads open. It is flagged as a fatal error after 60 seconds of continuous values over the maximum bounds.

What changes in the oven

Probe 2 now becomes the primary probe. Cooking is available, with some possible effects on temperature calibration, but cleaning is not. The manual’s answer for the owner is to call for service, and it adds that you can continue to cook while being aware that the oven may cook a little hotter or cooler than normal.

What a technician checks

The manual names a poor connection at the board or in the harness, a bad probe and a bad wire in the harness. The checks are the connections at the relay board and the probe state at the probe connector. The fixes run in order: secure the connection, replace the probe, then replace the harness.
