Fantastic Vent RV Vents and Fans - FV803350

  • Roof Vent
  • With 12V Fan
  • Vent
  • Fantastic Vent
  • 14W x 14L Inch
  • Tinted
  • Powered Lift

The rain sensor on this thermostat-controlled roof vent ensures that the dome closes and the variable-speed, reversible, 12V fan shuts off when rain or snow hits. Powered lift eliminates hand cranking.

    • 3 Manual speeds let you boost or reduce airflow as needed
    • Automatic, thermostat-regulated settings conserve energy by running only when preset temperature is reached
  • Rain sensor signals dome to automatically close and fan to shut off when wet
    • Powered arm opens and closes hinged dome - no hand cranking needed
    • Fan resumes when sensor is dry
  • Knob on vent housing allows you to operate dome by hand in case of power failure
  • Pop-out screen keeps insects out and easily detaches for cleaning

    • Rough opening size: 14-1/4" x 14-1/4"
  • Vent extends above roof:
    • 4-1/2" When closed
    • 11-1/2" When open
  • Fan motor:
    • Capacity: 920 CFM
    • Voltage: 12 volts
    • 4-Amp slow blow fuse
  • Warranty:
    • 2-Year limited on vent assembly
    • Lifetime on dome (lid)


This Fan-Tastic Vent roof vent has a built-in 12V fan that uses a thermostat to help maintain an even temperature inside your RV, camper, or enclosed trailer. You can also control the dome and fan manually with a built-in hand knob or with controls on the vent housing. 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 Thermostat

Air out your RV after cooking or just draw in some fresh air while you sleep. This variable-speed ceiling fan operates in 2 modes: manual and automatic. The fan activates when you move the fan blade rocker switch to the in or the out position, which designates the direction of airflow.


When using the automatic mode, you can preset the fan to maintain a desired temperature inside your RV. The thermostat dial is color coded, with dark blue representing the coolest setting and dark red representing the warmest setting. 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 control the fan manually, turn the speed knob on the vent housing. There are 3 speeds: low, medium, and high. There is also an off position.


Power Lift and Rain Sensor

Fan Tastic Vent Lift Dome

This Fan-Tastic Vent has a powered lift arm for the dome, so you don't have to manually crank it open or closed. The dome automatically opens when you turn on the fan. You can also use the small rocker switch on the vent housing to 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 it 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.

Absolute waste. It seems like when the company was sold they changed the programming and instead of fixing it or giving customers an option (read: a simple switch!) they made it so the rain sensor just shuts it permanently absolutely destroying any usefulness of the rain sensor. Customer service doesn't even understand the problem (e.g. getting up at 3 am because of a 2 minute rain at midnight to cycle the fan power) or alternative uses (e.g. using the fan to prevent overheating for longer periods- an all day hike). It now just closes permanently a the first drop of rain instead of reopening when the sensor is dry. I literally ripped this brand new fan out two weeks after install and a year later it's still sitting on my workbench because I refuse to hobble someone else with this absolute piece of garbage before I get a chance to override the problem with an FRM01 12v relay computer. I haven't bothered because 1. I have a better fan (the old version I was lucky enough to find) 2. this one has a chimney which sits up 2" higher 3. the new motor is weak enough that even if nothing else was wrong it would still be a mediocre fan. The old model has a horizontal front hinge and a black motor housing that extends into the lid. Beware a lot of images of the old model are still used in listings for the new model. 410384

Ask the Experts about this Fantastic Vent RV Vents and Fans

  • Solution to Replace Remote on Fan-Tastic Vent 6600R-417 Without Replacing Entire Unit
    I do have a solution for you that doesn't involve replacing your entire unit, but the Fan-Tastic Vent Roof Vent # FV803350, does not have a receiver built into it, so it doesn't have the option to operate through a remote. Therefore, using its replacements parts get you what you need. Take a look at the Fan-Tastic Vent Roof Vent Assembly Upgrade Kit # FV807359. This has everything you need (includes remote) to basically replace the "guts" of your Fan-Tastic Vent 6600R-417 unit and upgrade...

  • Replacement Motor For Fan-Tastic Roof Vent With Model B2000RBT Motor
    The model number B2000RBT that you mentioned is the motor model number for the Fan-Tastic Roof Vent. If the fan only runs for a few minutes it sounds more likely that the fan motor is going out. First, it is a good idea to make sure you are getting adequate power to the fan. Check for any loose wiring and make sure you have a proper ground connection. I think your issue has to do with power to the motor or the motor itself because it is a common issue. If you check your wiring and everything...

  • Replacement Parts for Fan-Tastic Vent 8000 Series
    There is not a fuse we carry for the 8000 Series of Fan-Tastic vent. It does use a 4 amp slow blow fuse so to make fuse access simpler you can use In-Line Fuse Holder # C58470-1 and if you need to replace the bow-tie bracket, motor, and blade the correct part is Replacement Fan Motor Assembly Kit # FVK8017-00

  • Adapter Recommendation for Powering Fan-Tastic Roof Vent with 110 AC Power
    Fan-Tastic Vents actually makes an adapter for a very similar situation. What you'd want is the # FV1101-09 which is normally used with their box fan but would work well with the fan # FV803350 as well. The power rating of the adapter is 1.5 amps at 110 volts which is more than enough for 4 amps at 12 volts.

  • Lift Motor Replacement for Roof Vent Where Motor Runs After Lid is Closed
    Most likely you have an issue with the roof vent's lift motor. If you have a Fan-Tastic roof vent there are a couple options for replacement motors and to pick out the correct one you'll need to base it off of the shape of the plastic housing. Vents with a pear shaped plastic housing use: # FVK6050-80 Vents with a diamond shaped thumb slide use: # FVK6010-81 If you have a different brand of roof vent let me know what you have and I'll see what we can find as a replacement.

  • Why Would Trailer Roof Vent Leak Water
    If your Fan-Tastic Roof Vent is leaking it's going to be a sealant issue between the vent assembly and the roof of the trailer. So you'd need to have the base of the vent resealed to the roof with sealant like the part # 34427034145-1 and that will take care of the leaking issue. Where is the red blinking light exactly? Does the vent still seem to work like normal?

  • Troubleshooting Lid Lift Function on Fan-Tastic Vent FV803350
    If your Fan-Tastic Vent # FV803350 is getting 12V power to the fan motor but not to the lid's lift motor you'll want to test the wiring within the fan to find the point where power is lost. This is most easily done with a simple probe type circuit tester like # PTW2992. The tester will allow you to probe the lid wiring both before and after the lid lift switches to see if it is the switches that are blocking power to the lid motor. The only other probable cause for this issue is a defective...

  • Troubleshooting Trailer Roof Vent that Blows Fuses When Lid is Lifting
    What roof vent assembly do you have? And what fuse is blowing? Is it on the vent or on the power wiring of the trailer/vehicle? Very easily could be a bad lift motor trying to draw too much amperage. If you have a Fan-Tastic roof vent the replacement lift motor would be # FVK6050-80.

  • Replacing or Repairing Rocker Arm on Fantastic RV Roof Vent
    When repairing or replacing the rocker arm like # FVK8011-05 on your Fan-Tastic Roof Vent, you shouldn't need to remove the entire fan assembly. Working from inside the trailer/RV and looking up into the unit, you should be able to first remove the screen. With the screen removed, you will want to remove the knob which is likely held in place with a screw. You may then need to remove a plastic tray which will give you access to the rocker knob. You can then see if anything has broke or...

  • Troubleshooting Fan-Tastic Roof Vent FV803350 That Doesn't Open Or Close
    First thing you will want to check is that the fan has power and is grounding properly. You can try using jumper wires to the vent wiring that are run to known ground and power to see if that works. Next, you can check the fuse of the fan to make sure it is not blown. Near the speed setting is a plug that holds a 4 amp fuse. I attached a picture that points out where it is. If the fan still works when you manually open the lid that would indicate a problem with the lid motor. Since...

  • Will Fan-Tastic Vent Roof Vent Work With Solar-Powered System
    Since you said your solar powered system is 12V, it would work great with the Fan-Tastic Vent Roof Vent, part # FV803350, as long as it provides at least 4 amps. This vent has a powered lift and a built-in rain sensor, and has 3 speed settings to let you control the air flow. This fan is designed for roofs up to 4 inches thick and the rough opening needed for installation is 14-1/4 x 14-1/4 inches.

  • How to Correct Squeak in Dometic Rain-Sensing RV Vent with Fan
    If your Airstream's Dometic powered vent has a visible accumulation of soils from regular use keeping the trailer free of cooking odors then you can certainly clean the fan blade and other accessible surfaces. It sounds like the squeak is coming from the fan motor itself, though, so for that I suggest a very light application of WD40 or a similar lubricant. If the squeak reliably stops after a moment or two then to be perfectly honest I would do nothing to the fan/vent other than clean...

  • Fan-Tastic Vent Rain Sensor Light Stays On All the Time
    The rain sensor doesn't have to be activated. When it gets wet it will automatically close the vent lid. When it dries it opens back up. But it sounds like yours has a short that is causing that light to stay on all the time. In order to get the replacement rain sensor you would need upgrade kit # FV803358 which includes the sensor.

  • Replacement Remote Control for my Fan-tastic Fan Model 6600
    This has come up before and when speaking with my contact at Fan-Tastic Vent regarding your model 6600 vent with the 417RF remote. She did confirm that the current model remote # FV9068-81 will not work with your vent model. The original remote for your vent is no longer available. In order to utilize a remote control, you will indeed need to upgrade the vent assembly to the Fan-Tastic Vent Roof Vent # FV807350.

  • Remote Compatible with Roof Vent with Fan and Powered Lift
    The Fan-Tastic Vent Roof Vent w/ 12V Fan and Thermostat - Powered Lift - 14-1/4" x 14-1/4" # FV803350 unfortunately does not have a receiver so a remote for that fan/vent is not an option. You can hardwire it to a switch, but that only will give you the fan speed or power options. To get the remote feature you would need one of the following vents: Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote - Powered Lift - 14-1/4" x 14-1/4" # FV807350 MaxxFan Deluxe Roof Vent w/ 12V Fan, Thermostat,...

    You should be just fine replacing your two roof vents with the Fan-Tastic Vent Roof Vent # FV803350 since these fit the standard 14-1/4 x 14-1/4-inch RV roof opening size. Since you are replacing two 12V powered vents with two similar units your existing switch should work but the air direction and thermostat functions will be operable on the new fan units themselves. If you want to check it for an amperage rating that's not a bad idea. Each of the Fan-Tastic Vent Roof Vents # FV803350...

  • Fan-Tastic Vent Roof Vent with Fan and Thermostat Amperage Draw
    I reached out to the manufacturer and the techs don't have that amperage for each speed of the Fan-Tastic Vent Roof Vent w/ 12V Fan and Thermostat # FV803350. They said that at start-up the fan will pull 3.5 amps but running will remain well under that amperage. The unit has a slow blow 4 amp fuse so it will not pull minimal amperage at 12V for continued operation.

It sounds like there is a circuit board issue and there aren't replacement parts for everything malfunctioning outside of this kit. If you also want the fan, you can use the # FVK8017-00.

    I reached out to my contact at Fan-Tastic Vent and she said the correct replacement motor for your 12V Vent Fan # FV803350 if it was manufactured after 2014 is the 17-rpm # FVK6010-81. This does operate at a higher speed than what originally came on your assembly but will work well. If you happen to have an older unit manufactured before 2014 the correct motor is the part # FVK6050-80 that has a lower 7-rpm rating.
