Fantastic Fan mysteries... (solved?)
 
Gang,

I spent some time figuring out my fantastic fan... and I discovered enough nuances that I figured I should share with you all. This has got to be the most confusing interface I've ever seen in a consumer product.

Here's the lowdown:

Thanks for taking the time to produce and post this. It was informative and useful—particularly the part about the red light. Has anyone else seen this light from bed at night and wondered what that was? Thanks, again.

Way to go, Thiel!

Fan use
 
Nice video! You have it figured out.

Couple of additional tips. The rain sensors on our 2017 23d were extremely sensitive. The fan would close if I was even sweating a bit. I disconnected the rain sensors in both fans and also disconnected them in our new 2019 FC 25. Takes just a few minutes to do and eliminates the fan closing when you need it most. We have the "Ultrabreeze" covers on both fans. It has to be raining really hard and the wind blowing just right to have any water droplets come in. We really like the "Ultrabreeze" covers. If you put them on get the optional bug screen. It is a separate part. About $10.00 each for the bug screen and maybe $50.00 for each "Ultrabreeze" cover. Takes about 20 minutes to install on roof.

When you remove the little round interior fan screen to clean it you can easily remove the fan blade for easier cleaning. Just remove the screw holding fan blade to the shaft. It comes right off and you can rinse it clean in the sink. Way easier than trying to wipe it clean in place.

My 2013 FC 19 had the red light and the "pull down on the knob" feature to disengage from the motor and open and close the lid. My 2014 23FB had the light, but not the 'pull down' feature, I would turn the knob and the motor would turn as well. My 2014 23d does not have the light, but does have the pull down knob to disengage the motor.

It seems so random what Airstream installs, even in the same model year.

I was blocked by my anti-virus software from viewing your video. Is there another way to see it?

Great Information
 
Great video. You actually solved an issue that I thought I was having with one of my fans. We were boondocking last week, had left the trailer with both vents open. It rained before we returned, but was not worried because of the rain sensors.

When we got back to the trailer, one of the fans was closed and one was not. Obviously, it was the speed setting on the fan which was set to zero, preventing the rain sensor from closing the fan.

You are correct, Confusing Fan is a better term for our Fantastic Fans, but my worries about a malfunction were solved. Thanks.

Thanks, I figured out the red light part by monitoring the drain on my battery when nothing appeared to be on. Not very intuitive! Great video.

Also, thanks for the point on cleaning the screen. Again, nothing apparent in the manuals.

Good stuff.

Good info. Now my problem is the fan does not currently turn, it did previously. I've attempted to check the fuse but am unable to figure out how to remove it; no matter how much I turn the housing with pliers. There is power to the raising mechanism which works fine off the wall thermostat. This is in my 1999lyx355

What about the knob that is beside the water drop?
 
I don't have an automatic fantastic fan on my 2003 bambi but I always wonder what that knob with the colors is for. Just figured out how to draw fresh air in from using one fan on and opening the window...a game changer. Any other tips about these wonderful fans would be helpful. Thanks.

Regarding the fuse, look carefully at the bottom of the fuseholder. I think I remember that mine has just a screwdriver slot in a flush cap. But according to the schematic I got from FF, all power goes through the fuse. So if your lifting motor is working and the fan is not turning, it isn't the fuse.


Check your IN/OUT switch. Some have an OFF position in the middle.


There is a button switch near the IN/OUT switch. It detects that the lid is open and turns on the fan. It may be stuck. Note the lid has to open pretty far before the motor turns on. Are you waiting long enough?

Not that mysterious, but what I don't like about the newer FF's is that once that the rain sensor closes the vent, it won't reopen. The earlier models would reopen after the sensor dried out. No longer an option.

In my experience with the FF’s in our 2014 25’’FC:
They get dirty quickly and not real easy to clean. The screens do pop off but the plastic retainer tabs are fragile and break easily. The metal screens can bend easily and make a terrible racket if not straight. I tried to remove the screw holding the fan blade in place in order to clean it but the screw is on really tight and I am afraid to force the issue.
Although my fans have the auto features I have never trusted them to work correctly when needed. Especially since one of the fans is directly over the bed.
