Viking oven shows F50; oven lights or auxiliary functions may not work.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed low-voltage transformer on control board, Blown low-voltage fuse, Shorted user interface board, EOC internal power supply failure

Safety: Disconnect power before accessing the control compartment. Capacitors on the board can retain charge.

Steps:

Remove the control panel and visually inspect the EOC for burned components, bulging capacitors, or blown fuses.
Test any replaceable low-voltage fuse on the board for continuity. Replace only with the exact type and rating.
If the transformer or power supply section is visibly damaged, replace the entire EOC.
Before installing a new board, inspect connected components (lights, UI board) for shorts that may have caused the failure.
