A model 5300 Fan-Tastic Vent uses a wall controller for fan speed, powered lid operation and rain-sensor override. Dometic's 5300 schematic identifies each harness lead between the 12-volt supply, fan motor, dome motor and 9054-90 C board.

This is the 5300 connection map for the wall controller marked #2. The matching 5350 schematic has a reversing-fan control function and differs at the fan-ground lead; a control panel that looks similar is not enough to establish interchangeability.

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
Locate the factory label on the vent housing, then compare the existing controller and PCB markings. In particular, use the 5300 drawing's WS-0608-81 ground reference rather than adopting the WS-0688-81 designation from the 5350 version.
