Viking Cooktop Error Code 3 Flashes

Three flashes on a Viking cooktop indicates an internal power device malfunction within the cooktop's main control system. This means a solid-state switching component responsible for regulating power to the cooking elements has failed or is operating incorrectly. The cooktop will not function normally while this fault is active. A qualified technician should diagnose the control board and associated wiring to determine the exact point of failure.

You should not continue using the cooktop while this error is active. An internal power device malfunction means the control system is not operating correctly, which could result in unpredictable element behavior or create a potential electrical hazard. Disconnect power to the unit at the circuit breaker and leave it off until the fault has been properly diagnosed and repaired.

Resetting the cooktop by cutting power at the circuit breaker for several minutes may temporarily clear the flashing indicator, but it will not fix the underlying hardware fault. If the internal power device is genuinely damaged, the error will return once the cooktop is powered and used again. A reset can be a useful first step to confirm whether the fault is persistent, but a component-level repair is required to fully resolve it.

This fault involves internal electronic components on the main control board, which makes DIY repair difficult and potentially unsafe without proper training. A technician can test the wiring harness and connections first, as a downstream short or loose connector may be contributing to the fault. If the control board itself has failed, replacing it requires working with line voltage components. Professional service is strongly recommended for this repair.

Repair costs depend on the root cause identified during diagnosis. If only wiring connections need to be cleaned or reseated, labor costs alone may range from around $100 to $200. If the main control board requires replacement, parts and labor combined can range from $300 to $600 or more, depending on the specific cooktop model and local labor rates. Getting a diagnostic service call completed first will give you a more accurate repair estimate.
