Note: This vent is compatible with FanTastic fans. It will not work with any other Dometic model fan.
This roof vent assembly kit uses a thermostat to help maintain an even temperature inside your RV, camper, or enclosed trailer. You can also control the dome (sold separately) and fan (sold separately) manually with a built-in hand knob or with the included remote control. A rain sensor is included as well to signal the dome to close and the fan to shut off when it gets wet.
Ceiling Vent and Fan with Remote-Controlled Thermostat
Air out your RV after cooking or just draw in some fresh air while you sleep. This remote controls the vent's thermostat as well as its manual and automatic speeds. You can control the direction of airflow - in or out - with the push of a button. Operate the remote control in your RV or place it in the included wall cradle so you will always know exactly where it is.
Manual and Automatic Operating Modes
This variable-speed ceiling fan operates in 2 modes: manual and automatic. An on/off button automatically lifts the dome (sold separately) and activates the fan. To use the manual mode, press the arrow buttons on the left side of the remote or turn the knob on the vent housing to increase or decrease the fan speed.
The manual speeds are listed on the remote from 10 percent to 100 percent. As you cycle through the speeds with the arrow buttons, an LED light next to the selected setting will light up. As you cycle, you may notice that the LEDs for 2 settings will be simultaneously lit. This means that the selected speed is the average of both of those settings.
To switch from the manual to the automatic, thermostat-controlled mode, press one of the temperature arrow buttons on the right side of the remote. When using the automatic mode, you can preset the vent to maintain a desired temperature inside your RV. The temperatures are listed from 60 F to 90 F. As you cycle through the temperatures with the arrow buttons, an LED light next to the selected temperature will light up. Again, when 2 temperature settings are simultaneously lit, the selected temperature is the average.
The fan's internal thermostat will sense the actual room temperature, and the fan will run until the preset temperature is achieved. When the temperature rises above the preset temperature, the fan will automatically kick on again. So when you go out, you don't have to waste energy by leaving the vent running at full blast just to ensure that your RV is cool when you return. And because the fan will activate anytime that the preset temperature is reached, you can set up the system to ensure that your pets remain comfortable while you're out.
To reverse the direction of airflow, simply push the air out/air in button while the dome (sold separately) is open.
Power Lift and Rain Sensor
This vent has a powered lift arm for the dome (sold separately), so you don't have to manually crank it open or closed. The dome automatically opens when you turn on the fan. An up/down button on the remote also lets you open and close the dome when the fan is not running.
And a hand knob is built in so that you can operate the dome in the event of a power failure.
A moisture sensor ensures that the dome will close when rain or snow hits. So you can leave the vent running or preset to run at a certain temperature, even if the forecast calls for rain. When the sensor gets wet, it signals the dome to close. With the dome closed, the fan blades will stop running. When the sensor dries, the dome will re-open and the fan blades will resume operation. To keep the sensor from activating in rain, snow, or humid and dewy conditions, simply add a vent cover (sold separately) to block moisture.
Installation
This vent requires a 14-1/4" x 14-1/4" opening in your trailer's roof and ceiling. To replace an old vent, install this vent into the existing opening. If your roof does not already have a vent, you will need to mark and cut an opening between roof joists to install this unit. And the 2-wire design makes it easy to have your vent hooked up and ready for use.

Beware if you have and old vent. My roof vent was installed in 2012. The 7350 Kit's screen assembly was 13 3/8", 1/8" to large. The screen assembly I removed was 13 1/4". I had to remove the shroud/bezel the screen assembly sits in to scrap/shave the opening with a utility knife. Even then I had to force the Kit screen assembly into the opening. Then the the five screw holes did not line up with the mounts dropping from the Fan/motor mount. Finally the lift motor will not catch the knurled end of the lift arm. I've spent half a day on this and seem to be stuck. Calling Fan-Tastic Vent on Monday.

excellent product. completely satisfied with the operation of this improvement.
the control gives more options than the old 2012 one did, and I really like the complete installation kit provided with it. the instructions color photos leave a lot to be desired - since they are mostly black or too dark to make out what is supposed to show, but being a retired electronics technician, figured things out quickly. I wish it was easier to get the mechanical vent cover lifting post lined up easier when one cannot see through the cover to align it visually, but got it finally. otherwise, fully satisfied with the change-upgrade kit.

Easy installation on a model 6600 that the remote had failed on. It requires 2 people for installation and installing the rain sensor requires going on roof. 100% Functionality of the original unit with remote. The fan is quieter on low speeds vs the original controls. I give it an A+!

The replacement or "upgrade" would not fit inside the existing fan housing from 2019. The original part does not have a return flange whereas the replacement part does, consequently it would not slide into place. It turns out that I really only needed the circuit board. So I swapped that out to the original housing and now the fan is back to working as it should. It would be nice to be able to order just the circuit board without the rest of the parts...

Great upgrade from a manual Fantastic fan without having to fully replace the vent fan. Reversible flow, variable speed, automatic operation based on temperature, and rain sensor are all included. Installation was straight forward with all necessary hardware and connectors included.

Nice repair kit but a few issues: instructions were unreadable, had to look on line to actually see the photos, and the motor did not mesh with the vent bar, insufficient length which required shimming. Another little nit-pik: I replaced both my vents with your kits, I received controllers with no instruction but not difficult to learn, and I got different color controllers, one black and one white. Overall, I'm satisfied.

I recently installed the Fan-Tastic vent assembly upgrade kit for my 2018 TaB 320 trailer. The upgrade process was relatively simple and took about 45 to 50 minutes to remove the original assembly and install the new one. I would recommend that you read the instructions a few times before starting your removal and installation process. It helped to mentally note on the new assembly each step referenced in the instructions.
The fan works great and the remote functions are straight forward. I really like the ability to set the fan at 10-20% speed without hearing fan noise. One drawback is that when you use the remote to operate the vent, it either opens it completely or closes it. If you want to run the fan with the vent lid partially closed, you have to do that manually.
Jamie from etrailer helped me ensure that I was purchasing the correct assembly for my trailer and helped expedite my purchase. I am extremely happy with my new upgrade and purchase experience with etrailer!

In 2014 I had upgraded one of three fantastic fans to operate with a remote. The remote control broke and was no longer available since Dometic had purchased Fantastic Fans and changed control boards and remotes. etrailer sent me the newer Dometic Fantastic fan upgrade with remote. Unfortunately, the unit shipped with a faulty control board. I tried to procure a replacement from Dometic but was unable to since they were out of stock and back ordered. However, etrailer came to the rescue and agreed to make the exchange. The new upgrade works better than the previous version in that the remote works from far greater distances. You can't go wrong purchasing from etrailer. They continue to meet and exceed with great customer support and communication.

After a year the fans and remotes are working just fine. The new lid motors are about twice as fast as the old slower units. The lids open and close faster and seem quieter - maybe since they dont run as long. Thanks again etrailer!

Very pleased with the upgrade kit, despite the fact that it arrived without any sort of installation manual in the box. This is likely not due to the seller, but more likely an oversight on packing from the manufacturer. An operation guide was included, but nothing about wiring. Thank goodness for [online videos] and others who posted how to connect everything. The fan works perfectly now and exactly as described. I'm super-pleased.

Received from this upgrade from UPS and had it installed within an hour. Our fan before the upgrade was 3 speed and temperature controlled. The improvements with this kit make the old fan amazing especially remote control. It’s also quieter and draws a lot less amperage.

Pro’s - Relatively easy upgrade with all the features of the latest Fantastic fan. Upgrade is all done inside, no roof work except to locate and install rain sensor with one screw. Roof seal is not disturbed. Minimal wire splicing required.
Con’s - Instructions are poorly written with tiny pictures of the area being discussed, they can be figured out but the poor instructions turn a 1/2 hour job into an hour plus, spent more time trying to understand the instructions than doing the actual work. Holder for the remote needs to be tighter or have a small clip to keep it in place. It was designed as though it was being hung in your house, not a trailer bouncing down the road. I modified mine so the remote won’t pop out during travel.
Glad I made the upgrade.
NOTE: BE SURE TO ORDER THE RIGHT VERSION THAT WORKS WITH YOUR EXISTING FAN. YOUR EXISTING FAN IS EITHER “CLAMPED IN”, OR “SCREWED IN”.

I have been very satisfied with my fan-tactic roof vent upgrade kit vents. They were easy to install & work great. My wife loves them. She no longer has to get a step stool to manually open & close the vents - with the push of a button, they open or close. You can also control the speed of the fan. I would definitely recommend them! And the sales people at etrailer are the best - very helpful & knowledgeable.

The product was fine - pretty much just what I needed. The service when I called etrailer was professional, courteous and prompt. The problem seems to lie in their systems. I had to order 9 times, the first 7 orders were rejected for card payment issues. At first they told me to call my credit card company. The credit card company told me they were approving the payment but etrailer was rejecting it. After a few more payment attempts and in a few more calls to etrailer, each of which was courteous and professional, I was told is was a "system problem" that they could do nothing about, but that I could try PayPal. Eventually I tried PayPal and the order went thru. It was delayed a few times, I had to reorder the item a few times and it was a huge hassle, but no one else had the fan so... what do you do.
When I got the fan it was fairly easy to install, but the lift arm for the fan lid did not fit so I had to use the old one. The instructions are xxx at least for my replacement, but you can figure it out with a little effort.
All in all it was a hassle to purchase but I'm happy now because everything works.
good luck!

I have a 2020/21 Dometic Fantastic Fan 1450. I installed the upgrade kit and the new lift arm is not compatible. etrailer tech support was (uncharacteristically) not helpful - telling me that there must be a track on my lid for the ne arm and that I should look harder. Having checked with other owners of a 1450 fan of the same year, they have found the same issue. Once I replaced the original control arm it worked; however, for some strange reason, when turning on the main trailer power switch, the fan comes on by itself without the lid opening. Once you turn the fan off and back on using the remote, it works perfectly until you turn the main trailer power switch off and on again.
Both Dometic and etrailer could do better as many hours were spend needlessly working on this.

This kit is to convert a 3 speed fan, to a variable speed. It uses a fraction of the energy of the 3 speed, which is great for boondocking where power is limited. Also comes with power lift, remote, and rain sensor. Install took 30 minutes, including removal of old parts. Be sure to read all instructions before starting, there is a jumper on circuit board that either stays or is removed depending upon which fan motor you have. I also have a vent cover installed which prevents the hatch from completely opening. The automatic opener stops as soon as it hits limits and works fine. Great product and service from etrailer. Also note there seems to be two styles of this kit. One has notched corners, and the other does not. Be sure to verify which style you require. I installed on a NuCamp 2018 T@b 400, which had notched corners.

Etrailer provided easy ordering, fast shipping, and immediate and useful help with a small issue. The fan is exactly what we needed to upgrade our existing roof vent to one with more speeds that uses a much smaller portion of our battery storage.

The fan upgrade was easy to install and can be completely done from the inside. I did not have to get on the roof at all! I my case I did not need all of the parts in the kit but the kit does come complete with everything you will need EXCEPT for a crimp connector or two. The hardest part is installing the rain sensor from the inside as you cannot see it and do it by feel. Still easy just a bit of time.

1 year in and still glad I did the upgrade! These fans have been working just fine this whole time. The only, very minor, issue is the motorized lid will tend to stick closed. But by no fault of its own - the lid will stick to the seal when closed for a period of time or after a hot day. The same thing happens with any of the roof vents that utilize this type of lid and lift mechanism, power or hand crank models.

- Will Dometic FanTastic Roof Vent Assembly Upgrade Kit Fit Older Fan-Tastic VentHey Garth, yes the Dometic FanTastic Roof Vent Assembly Upgrade Kit # FV807357 will work on your older Dometic fan. The frame design hasn't changed since then so it will bolt right up.

In order to install this vent, you must have a 14-1/4" x 14-1/4" opening approximately in the trailer's roof and ceiling and the roof can be no more than 4" thick. These are standard dimensions for a vent opening. If this does not work for you please send measurements and I will do my best to find a solution. I have attached a review of...

Since your RV and vent is a little older the replacement part needed for it is not available. In this situation your best option is to upgrade your FanTastic roof vent to the current design with the upgrade kit part # FV807357. Is your vent the same as what came with the Winnebago?

We do have a solution for needing to replace the circuit board but the only way to accomplish that is to go with the upgrade kit part # FV807357 which basically replaces the inner section.

Your only option then is to replace the entire assembly with a brand new one like the Dometic FanTastic Roof Vent w/ 12V Fan and Remote # FV807350. If there is anything else you need help with, or that I can help you with, feel free to drop a comment and let me know!

Richard, with your FanTastic 5250 vent being obsolete your only option is to upgrade it with the Kit # FV807357 you found. You may also need a new inner garnish which you can determine by following the instructions on the bottom of page 4 which I have linked near the bottom of the page. Another option you might consider is just going with a new vent like the MaxxFan # MA00-04500K which has better replacement part availability should something break in the future.

The Fan-Tastic Vent Roof Vent Assembly Upgrade Kit part # FV807357 is designed as an add on to existing vents. The add on while not identical does give you the auto or manual setting and in manual you can choose between 7 fan speeds. The complete assembly has more options than what the stock photo shows on the remote.
view full answer... - How Does Fan-Tastic Vent Upgrade kit part # FV807357 InstallThe included hardware of the Fan-Tastic Vent Upgrade kit part # FV807357 that you referenced does screw to the garnish that's already installed which is what clamps to the roof opening. While online install instructions aren't available it's basically just a matter of using the included hardware to lower the inner section of the vent assembly and then replacing it with this after making a few wiring connections. Printed instructions to come with this though.

If you have the high or low style base you want the # FV807359. The upgrade kit includes the control board and is the only way to replace it since it is not sold separately. This will also give you an additional screen assembly, powered lift, and remote control. Since you are already replacing quite a few parts, it might be a good idea to just replace the entire fan.

view full answer... - Replacement Roof Vent w/ 12V Fan for a Fantastic Vent Model 5250I am sorry but there are no replacement control panels or remotes available for the Fantastic Vent Model 5250. That model of vent is obsolete and they aren't making replacement parts specifically for it anymore. You can either try to source the parts through used vendors or you can replace your fan with the MaxxFan Plus Roof Vent w/ 12V Fan, Thermostat, and Remote - Powered Lift - 10 Speed - Smoke item # MA00-04500K. I have linked a review video below.
view full answer... - Difference Between Fantastic Fan Upgrade Kits FV807357 and FV807359 The big difference is the corners of the main panel of the # FV807357 are cut out with small section to allow access to mounting hardware and the # FV807359 instead does not have this area cut out. So you'd want to look at your vents to see if you need the cutouts or not.

Because your vent cover lift arm is different, it won't be a direct replacement. If you want all these functions, I recommend removing your current vent and installing the Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote - Powered Lift - 14-1/4" x 14-1/4" # FV807350 as a replacement.

Check your switch to make sure it has not gone bad. This can be done by removing the power and ground from the back of the switch and connecting them directly to a 12v power source. If that doesn't work then it is most likely the board. In order to replace the board you would have to use the Fan-Tastic Vent 7350 Series Upgrade Kit Item # FV807359. Keep in mind this is for...
