Viking Cooktop Error Code 6 Flashes

The 6 Flashes code indicates a coil temperature sensor malfunction. The cooktop's control board monitors the sensor's signal to track coil temperature, and when that signal falls outside the expected range, the unit shuts down and displays this fault. The issue can stem from a failed thermistor, damaged wiring, or a loose connector.

No, you should not attempt to operate the cooktop while this fault is active. The 6 Flashes code means the control board cannot reliably monitor coil temperature, which removes a key safety protection against overheating. The unit should remain off until the sensor malfunction is diagnosed and corrected.

Repair costs vary depending on what component has failed. A replacement temperature sensor or thermistor is typically an inexpensive part, and the repair may cost anywhere from $100 to $250 including labor if only the sensor and harness are involved. If the control board has also been damaged, total repair costs can rise to the $300 to $600 range or higher depending on the specific model and local labor rates.

A knowledgeable DIYer can inspect the sensor wiring harness for visible damage and reseat loose connectors without special tools. However, confirming a failed thermistor requires a multimeter to check resistance values, and replacing internal components on an induction cooktop involves working near high-voltage capacitors that can retain charge even when unplugged. If you are not comfortable with electrical diagnostics, a qualified appliance technician should handle the repair.

Unplugging the cooktop or cutting power at the breaker for several minutes may temporarily clear the fault code, but it will return if the underlying sensor problem has not been fixed. A reset does not repair a failed thermistor or damaged wiring, so the error will reappear once the board attempts to read the sensor again during operation.
