Viking Cooktop Error F-C

DIY Fix Basic checks and reporting the unknown error

1. Record the exact conditions when F‑C appears (e.g., which zone, actions right before appearance).
2. Ensure the cooktop surface is clean and dry and that proper cookware is used.
3. Power‑cycle the cooktop by turning off at the breaker for 1–2 minutes then restoring power to see if the code clears.

Technician Only Professional diagnosis and internal inspection

1. Consult the specific model’s official service manual for cooktop error codes.
2. Inspect internal wiring harnesses, control board connections, and sensors for faults or loose connections that might trigger an undefined code display.
3. Use diagnostic tools (multimeter/diagnostic mode) to capture error behavior and interpret any internal fault registers.

Parts needed: Diagnostic tools, Control board/test harness, Sensor modules (if identified)
