Dacor Range, Oven, Cooktop Error Code F8

The F8 code on a Dacor Renaissance Induction cooktop means that the NTC temperature sensor connections for the front and rear cooking zones are reversed on the induction generator assembly. This is a manufacturing defect where the thermistor wires were connected to the wrong zones during production. The cooktop cannot operate safely with this condition, so it shuts down and displays the fault code. Resolving the error requires replacing the induction generator assembly.

No, the cooktop should not be used while displaying the F8 error. The reversed NTC thermistor connections mean the induction generator is receiving incorrect temperature data from the cooking zones, which prevents proper thermal regulation. Continued use could result in uncontrolled heating or component damage. Discontinue use and have the induction generator assembly replaced before operating the cooktop again.

Repair costs for an F8 error will vary depending on parts availability and labor rates in your area. The induction generator assembly is a major component, so parts costs alone can range from several hundred to over a thousand dollars, with additional labor charges on top of that. Contacting a Dacor authorized service center for a specific parts and labor estimate is the best way to get accurate pricing for your model.

The F8 error is caused by an internal wiring reversal inside the induction generator assembly, which is not serviceable in the field. The entire induction generator assembly must be replaced to correct this fault. Because induction generators store high-voltage charge and involve complex power electronics, this repair is strongly recommended for qualified appliance technicians only.

Resetting the cooktop by cycling power will not permanently clear the F8 error because the underlying cause is a hardware defect in the induction generator assembly. The fault will return as soon as the unit powers up and detects the reversed NTC connections. Only replacing the induction generator assembly will resolve the condition and allow the cooktop to operate normally.
