Three flashes in a row point to the sensor that reads the power device temperature.
Model compatibility: Viking reuses codes across series and model years, so 3 FLASHES may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Three consecutive flashes mean a malfunction of the power device temperature sensor.
When a Viking induction LED blinks three times in succession, the cooktop and rangetop manuals report a power device temperature sensor malfunction. Note that the fault lies with the sensor, and not necessarily with the device it monitors.
Why the sensor has an entry of its own
A temperature sensor is how the control holds the electronics to their limits. Without a trustworthy reading, the cooktop can no longer judge safely whether its power device is overheating. For that reason Viking separates the sensor from both the one-flash and the two-flash signals.
Where it sits among the first counts
One flash (brief interval): power device over temperature.
Two flashes: power device malfunction.
Three flashes: the temperature sensor of that device malfunctions.
What to do
For three flashes the manuals give no steps and no cause. A note by the flash table covers the case where flashing keeps going after the adjustments described for ordinary flashing: call a service technician. Better not to use an element with a pattern, whereas those without can stay in use.

4 flashes: a comparable sensor fault, this time at the coil.
2 flashes: a fault in the device and not its sensor.
