Fantastic Fan is leaking how come?
 
The front Fantastic Fan in our 2017 19-footer is dripping water when it rains.

What can I do?

Drips are coming from inside the fan, not from the edges.

How could this water get in?

This is happening with the trailer parked with a drizzling rain, no high wind.

Might be coming from elsewhere and dripping down the electric wires to the fan motor. It might take some disassembly to find the cause.

I experienced a bad sealing job on a Fantastic Fan from the factory in my 2019 FC. Upon inspection, it was obvious to see how they missed a few gaps. In a heavy downpour, it leaked much like youre saying.

I took my fan apart a short time ago for a different reason. I can see how both explanations can work especially Jay's. The outer frame is inside the bezel and the bezel can trap the water and cause it to drip out the center where the screen is, but so too can a leak from another source as tbrowne suggests.

We had this problem a few months back, the exterior seals are leaking. The water can sit in the internal housing and it won't be initially obvious where it is coming from. the short term fix was spray sealant around the unit on the roof until a better patch could be applied in better conditions.

Traveling water.
 
:brows:The water drips could be starting just about anywhere up on top. Water will always take the route of least resistance. Ive been fooled more than once. It can follow wires, edges of the metal or not. Maybe just a slight crack in the plastic could be the trouble. If it stops raining there is no need to fix it but if it is raining its too wet to fix.

I use the fantastic fan vent cover, so we can leave ours open in any rain. Don't have to worry about it closing when it starts raining. I bought 2, can only use 1 on our 28 with factory solar. If anyone is in the SC area, let me know you can have the other new one. We keep our fan vent cracked 100% of the time with the cover on.

I had to remove the inner decorative frame of the fan from inside the AS and noticed the water dripping from the metal screws. Used Sika flex caulk from the inside on each screw and use the white self leveling caulk recommended by AS (forgot the name) from the outside, no more leaks since.

Hope this helps.

Thanks. This is helpful.

The cap has minor scratches, no obvious breaks, but in a hopeful attempt to fix I ordered a new cap (and for now wrapped a garbage bag over the whole unit).

Maybe the scratches are deeper than they appear and are letting some water in.

Sealant around the fan looks good ... but, who knows! Whole adventure is frustrating and stressful.

Hi Scott, our Fantastic fan lift cover is cracked beginning from the hinge rivets. We could use the vent cover mentioned and gladly would pay something for it. Probably dont still have it but if you do well be coming north on I-95 to I-26 to Ohio on about 5/30/2021.

Kindly, Mark

I contacted the makers of the Fantastic Fan, and they sent me a replacement dome under warranty. They were good about it no arguments, and I did not have to ship them the old one.

Now I need to get over my nervousness about climbing up on the roof of the Airstream and get up there, unscrew the old dome and screw in the new.

Before I do, a question: Do I need to seal the screw holes with anything before I lash down the new dome?

Both ours were also leaking, along with the skylight, tv & radio antenna mounts, and black tank vent. :sad:

Best to do a thorough roof check, JC thinks only Eagles & Angels see the roof.:lol:

WS....ONLY PUT WEIGHT ON THE RIVET SEAMS when on the roof. I use 3m 4200 for all semi-permanent AS sealing. Yes. I use it on all screws & rivets. It's also available in the larger 'gun' tubes.
