Dacor Oven Error Code L80

L80 means the lower meat probe circuit has been detected as shorted. The oven's control system measures the probe using an analog-to-digital converter, and when that reading stays above the value 0xF0 for 60 continuous seconds, the L80 code is triggered. This can be caused by a dirty connection port, a failed probe, or a wiring issue in the probe circuit.

A power reset may temporarily clear the L80 code, but it will return if the underlying short condition in the probe circuit is not corrected. Because the code requires 60 continuous seconds of an abnormal A/D reading to trigger, the fault will reappear as soon as that threshold is met again. Resolving the root cause, whether it is a dirty connection, a bad probe, or a wiring fault, is necessary to clear the code permanently.

If the fix is simply cleaning the probe connection port, there is no parts cost involved. Replacing a failed meat probe typically costs in the range of $30 to $80 for the part depending on the model. If the control board requires replacement, costs can range from $150 to $400 or more for the part alone, with additional labor costs if a technician performs the repair.

Start by removing the meat probe and inspecting the probe connection port on the oven cavity wall for grease or debris. Clean the port thoroughly and test with a new meat probe to determine if the original probe has failed. If the error continues with a new probe, the wiring harness or control board input circuit should be inspected by a qualified technician.

The L80 code specifically relates to the meat probe circuit, not the main heating system. Basic oven baking and broiling functions may still operate, but you should not use the meat probe feature while this fault is active. It is best to resolve the code before relying on any probe-based cooking function, as the probe temperature readings would not be accurate or reliable.
