Updated 12/08/2025 | Published 12/11/2024

Question:

I have a 2007/8 National Dolphin. It has a saloon combo Exhaust Fan and Air In. Model 6504. I am looking for a replacement motor with fan blade and mounting. Motor 6504-314R. 2 wire, 12 volt, 25 watt. I hope one is available....! It was raining to get this info. I can take and send photos if needed later. I am recently aware that the wall controller is no longer available. The one I have still works. It is the motor that is now defective. Regards, Thank you..!

Hey Juan, so the part numbers you mentioned reference that you have a Dometic RV roof vent so for a replacement motor that comes with mounting bracket you'd want the part # FVK8017-00.

Hey Juan, how did the replacement fan motor kit work out for your National Dolphin? Knowing how it fit and performed could really help others trying to fix the same vent setup.

@JamesonC The Fantastic Fan assembly received was an exact match. The only issue was, I had to climb up on the roof to release the Roof Door Cover. The existing mounting screws were easy to extract and replace. Two wire splice, remount the Roof Door Cove and the job was completed in 25 minutes. Climbing up and down the ladder to the roof took 8 minutes. Fan operates like new. I also cleaned the outside housing and the Door Cover.
