The Fan-Tastic Vent 5350 combines a wall-operated lid, reversible 13-speed airflow, a rain sensor and a powered lift motor. Its Dometic wiring diagram is the right reference for tracing the original connections to the fan and dome motors and identifying the 9054-90 C board.
Original Dometic 5350 wiring schematic
Dometic identifies controller #1 on this model. Although the 5300 and 5350 share a board-family designation, the 5350 adds reversing-airflow operation and shows a different fan-ground harness reference. Check the full model code and connector positions before ordering controls.

These are actual NewRVParts product photos to help identify the kind of component being serviced. Match the original manufacturer's part number, colour, connectors and production version with the individual listing before ordering.
Confirm the correct vent before ordering
Confirm the label is a 5350, then match the installed fan blade/hub, 17 RPM motor cover, fuse holder and switch part numbers. The items pictured below are real replacement listings, but the electrical diagram alone does not approve each item for every 5350 production revision.
