Dacor Range Oven Cooktop Error Code F8

The F8 error code on Dacor Renaissance Induction cooktops indicates that the NTC (Negative Temperature Coefficient) thermistor connections for the front and rear cooking zones have been wired in reverse order on the induction generator assembly. NTC thermistors are temperature-sensing components whose electrical resistance decreases as temperature increases. The induction generator uses these sensor signals to monitor and regulate cooking zone temperatures precisely. When the front and rear NTC connections are swapped, the generator receives temperature data from the wrong zones, causing a fault condition that triggers the F8 code.

This is classified as a manufacturing error, meaning the incorrect wiring occurred during the production or assembly of the induction generator unit itself, rather than from a field failure, user error, or installation mistake. The induction generator assembly is the central power and control module that converts household AC power into high-frequency alternating current to drive the induction coils. Because the misrouted NTC wiring is internal to the generator assembly and not accessible for field repair, the entire induction generator assembly must be replaced to resolve this fault.

Technicians should not attempt to re-pin or trace wiring on the existing generator board, as the NTC leads are integrated into the assembly in a manner that does not support field modification. Once the replacement generator assembly is installed with correct NTC routing from the factory, the F8 fault should clear and normal zone temperature control will be restored.
