Dacor Oven Error Code U80

The U80 code means the oven's control board has detected a shorted condition in the upper or single meat probe circuit. The analog-to-digital value from the probe thermistor has exceeded the threshold of 0xF0 for 60 continuous seconds, which the control treats as an abnormal short. The most common culprits are a dirty or wet probe socket or a faulty probe with an internal short.

The U80 fault is specific to the meat probe circuit and does not necessarily prevent the oven from operating for standard baking or broiling functions. However, you should not rely on the meat probe for temperature monitoring while this fault is active, as the readings will be unreliable. It is best to resolve the fault before using the probe feature again to avoid inaccurate cooking results.

A power reset may temporarily clear the U80 code, but if the underlying cause such as a shorted probe or contaminated socket is still present, the code will return within 60 seconds of the fault condition being detected again. A permanent fix requires addressing the root cause, either by cleaning the socket, replacing the meat probe, or repairing the socket and wiring.

In many cases, yes. Start by unplugging the oven, then inspect and clean the probe socket to remove any food residue or moisture. If you have access to a replacement meat probe, plug it in and check whether the error clears when the oven is powered back on. If a new probe resolves the issue, you simply need to replace the original probe. If the fault persists after cleaning and swapping the probe, a technician should inspect the socket and wiring.

If only the meat probe needs replacement, the cost is typically in the range of $30 to $80 for the part, depending on the specific model. If the probe socket requires replacement, parts and labor could range from $100 to $250 or more. A wiring harness repair or control board diagnosis by a technician would add to that cost depending on what is found.
