Thank you so much for this video! Prior, trying to figure it out was bewildering, to say the least. Your explanation & instructions were spot-on and readily followed. Again, thank you!

Thanks. What a confusing setup! I was going to spend $400 to replace it, but thanks to you I am all good to go now.

You have simplified the operation of fan wonderfully! Thank you!!!

We're in the middle of building our box van conversion tiny home and you put out a lot of great information that is going to help. We were just looking into purchasing a fan for our new tiny home.

Excellent, informative video. Much better than the manufacturer's information booklet. I used to simply turn off all switches until the fan blades stop spinning and the vent cover finally closes. Now I know the proper sequence. Thanks.

Great video! Clear, comprehensive, but to the point. Well done and thanks!

Great video - so clear to understand. Thank you.

Thank you. This is what Dometic should have on their website. Their manual is also very poor in explaining the controls, so again I thank you for uploading.

Most excellent....best instructional I have seen on the Fantastic Fan

Very informative and concise video. Well done.

Thanks, best Fan-tastic Fan explanation ever. Now I totally get it.

Fantastic...no pun intended. Conincedentially, I was just out in trailer yesterday doing spring cleaning and telling myself i needed to read up on how it worked because it was so confusing. I was cranking it open and closed and never sure why the red light was on. Anyway, well done with this and all you do. Thanks!

wonderful information

Exactly what I wanted to know. Thanks , Peter from Sydney Australia

Cool video! Thanks for sharing...😎👍

Great explanation. Thank you.

Thanks for the video......I agree 100%. I usually just turn all the knobs till the darn thing turns on.

Oh, if you "teach/show and tell" like this all the time, I would love you to be my husband!! Now, all kidding aside, THIS WAS AN EXCELLENT VIDEO AND I APPRECIATE YOUR TIME. Very thorough and easy to follow verbal and visual instructions.

Awesome video

Thanks for doing this.

I was baffled as to why the fan lid was constantly opening and closing itself all the time, even though the switch was in the off position. I’ll be sure to set the dial to zero now! Thank you for your very informative video!!

Great explanation thank you

Thanks for this !

First of all thanks for the video. Could you explain what makes the fan change direction? I know it will but i don’t know how i did it. Thx

Great video.

Ours is tied into a thermostat on the wall.. do you have any videos on that setup and operation? thank you

Excellent job explaining the Fantastic Fan. We recently got an AS and it took me some time to figure out how it works. The salesperson has only limited knowledge:(

Great info in your video. Think we need info on the advanced silliness of the thermostat. Sometimes fan works & sometimes it doesn't. Can you help?

Curious if you know if you can only open it partially to vent the air or does it have to be fully open? Wanting to be able to get for sure through without being fully open if it’s partially raining. Can you crank the hand knob or will that mess up the motor? Thank you

Thank you for this video. I could not get my cover to come down. It was that I had the control on 0.

Wow so glad this popped up in my feed. So informative. The book that comes with the fan is so bad. Now I know why I couldn’t get it to work. It has to be on 1+ dumb, why do they have a fan on off switch? Thanks again

What about the blue & red dial next to the blue rain sensor what does it do...how does it work ?

Wow thank you 🙏🏼

My fan has all those controls on the wall in it's own box. I also have an outdoor hood over it all. Just stopped working. Fan hood goes up and then nothing.

THANK YOU!!!!!!!!

Thanks, i thought i was going to break the screen until I saw this video! Very helpful

Thank you

Another great vid. How about the other fan above the head? My gasket got brittle and ended up chucking it and I can't find a replacement unless you buy a cover for it and my cover is fine. I'm still ISO finding a hack gasket 😁

Thanks for the info! Can you tell me why the fan shuts off when I change the temperature knob?

Any fan motor maintenance ? Mine makes a noise like it needs oil

How do you disable the rain sensor? Mine never lets the fan run.

Question from a new owner. How can I get the cover to only go up say a quarter to half instead of it being fully open?

I want to share my review of the Fantastic Vent 3350 because my experience with the fan is anything but fantastic. I bought mine 18 months ago, as friends, who have an older model, said it was very good. However mine makes a lot of noise and pushes so little air that I can barely tell if I have it set to exhaust or blow. If I turn it up to get more airflow it becomes even noiser! The rain sensor closes the vent at night so I can only assume that it senses the night time moisture and closes even though it is NOT raining. My friend's older model seems to push more air than my newer model. I get much better & quieter airflow from my little Sirocco fan and it was only $!60 not over $600. Dometic agreed to replace the fan and the airflow improved a little but it is still very noisy AND the rain sensor closes the fan at really odd times like late afternoon. So we can't use the fan unless we manually open the cover. So in summary, I have found it an appallingly poor performing fan that is just not worth the money.

Sorry to ask a dopey question, but you do not mention the fuse. Is that just a pull it out and plug in a new one change out? Could it be the source of my problem. I have two fans in an older RV that are not working.

Your fan may be wired incorrectly. On my fans the on/off toggle switch turns the entire unit off....no power to anything...

Does it blow inside and how cool does it make it?

Great video, but you left out how to operate the manual knob to raise and lower the lid. That big black knob doesn’t seem to turn manually (even though you would think it is there for that purpose).

How do you close it, tho? Mine only opens. :(

Ours is making noise like it wants to open on its own. Any idea?

Mine is much simpler and is more manual. I must use the handle at the top of the screen. The handle can fall apart and it is a pain to put it back together. There is a video about how to put the handle back together.

Do you need to lubricate the motor ever?

Wait 'til the sensor starts acting up on you and makes you fight with the fan or squeezes the fan to close tighter with an annoying noise at night 🤣. The sensor is at the top in the area where that blue drawing is, accessible from the roof, top of fan, I had to change mine only a year and a half old, it wires inside aroun.,, Hard to explain But sensor does wear out and act up when humid or raining. DIY ok Job.

That red light is just stupid. If its daylight out there you will never see the red light! Why not just put a light on the inside of the unit to be seen day or night! Also why not just have one power button, either its on or its off not the crap that they have on this fan!

Read the manual.
