Dacor Range, Oven, Cooktop Error Code L80

L80 indicates a fault in the meat probe circuit for the lower oven. The control board has detected that the probe or its associated wiring is either shorted or has an open circuit. This fault affects probe-guided cooking functions and requires inspection of the probe, cable, and wiring before the issue can be resolved.

The L80 fault is specific to the meat probe circuit and does not necessarily indicate a hazard with the oven's main heating functions. However, any probe-based cooking mode will not operate correctly while this fault is active. It is best to stop using the probe until the fault is diagnosed and resolved to avoid incorrect temperature monitoring.

If only the meat probe needs replacement, parts typically cost in the range of $30 to $80 depending on the model, making it one of the more affordable repairs. If internal wiring or the control board is involved, repair costs can rise to $150 to $400 or more including labor. Getting a diagnostic assessment from a qualified technician can help narrow down the expense before committing to a repair.

If you are comfortable using a multimeter and working around appliance wiring, many of the diagnostic steps are DIY-friendly. You can visually inspect the probe and cable, clean the probe receptacle, and test probe resistance with a multimeter. Replacing a meat probe is typically straightforward. However, if the fault traces back to internal wiring or the control board, professional repair is recommended.

Resetting the oven by cycling power at the breaker may temporarily clear the code, but it will return if the underlying fault in the probe circuit has not been corrected. A reset alone is not a repair. The probe, cable, and wiring must be inspected and the faulty component replaced to resolve the error permanently.
