Error codeU80 / L80
ApplianceWall Oven
Quick answer
U80 and L80 on a Dacor wall oven mean the meat probe is shorted and has been disabled. Baking and cleaning still work.
Model compatibility: Dacor reuses codes across series and model years, so U80 / L80 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
A shorted meat probe was detected, so the meat probe is disabled while cooking and cleaning stay available.
If your Dacor wall oven display shows U80 MEAT PROBE or L80 MEAT PROBE, the oven has found a short in the meat probe circuit. U80 refers to the upper or single oven, and L80 to the lower oven of a double.
What U80 and L80 mean
The control registered a shorted meat probe, either in the probe itself or in its socket or wiring. After 60 seconds of continuous out-of-range readings, the oven disables the meat probe. Cooking and cleaning are still available, but the meat probe options are not.
Which Dacor ovens show it
This code appears on Dacor Renaissance EOR and MOR wall ovens and on the 27-inch and 30-inch single and double ovens covered by the Dacor wall oven service manual.
What to check
Make sure the oven connection end of the meat probe is clean.
Make sure there is no food, moisture or other substance in the meat probe socket.
If the code stays, call for service.
What a technician checks
A technician tests the socket connection on the relay board, tries a new meat probe to compare readings, and checks the wiring for contact with sheet metal. Depending on the result, the probe or the socket is replaced.
