Reversible, Variable-Speed Fan with Thermostat

MaxxFan Plus Fan Motor

The 12-volt, variable-speed fan has 2 modes of operation: manual and auto. When the fan is in manual mode, you can choose from 10 different speeds to increase or reduce the airflow as needed. Auto mode works in conjunction with the fan's thermostat.

To enter auto mode, press the auto mode button on either the remote control or keypad. Once the fan is in auto mode, the thermostat is activated with a set temperature of 78 degrees F. Pressing the arrow keys on either the remote or keypad changes the set temperature in 1 degree increments. When the thermostat is set, it senses the room temperature and automatically turns the fan on if it is above the set temperature. The fan shuts off when the set temperature has been reached. If the room temperature rises, the fan turns on again. This keeps your RV cool and comfortable and saves you from having to adjust the fan by hand. The auto mode also saves energy by running the fan no more than necessary, especially while you're away or asleep.

This fan is reversible, which means you are able to both exhaust stale air out of your RV and bring fresh air in from the outside. To enter ceiling fan mode, close the vent while the fan is still running. The fan then circulates the air inside your RV like a ceiling fan.

The fan has a fuse-protected, ball bearing motor that is sealed to keep out dust, dirt, and moisture.

Flush-Mounted Keypad

Keypad for MaxxFan Plus

The flush-mounted keypad on the vent enables you to operate the vent and fan, including opening or closing the dome and turning the fan on or off. You can also control the fan speed, the direction of the airflow, and the set temperature for the thermostat.

Manual-Lift Dome with Twin Arms

MaxxFan Plus Dual Arms - Manual

The dome on this roof vent is constructed of durable high-density polyethylene, and it is translucent so that some natural light can shine through. When it's closed, the dome provides a seamless, low-profile appearance that blends into the roof of your RV.

Unlike a dome that has only 1 arm, this manual-lift dome is supported by 2 sturdy arms so that it will not flutter during high winds or while you are driving.

MaxxFan Plus Manual Knob

And a manual hand knob is built into the underside of the vent to allow you to open and close the dome. Pull the knob outward, turn it to where you want it, and push it in to lock the dome into place.

Removable Bug Screen

MaxxFan Plus Bug Screen

This vent has a bug screen that helps keep insects and debris out of your RV. It is secured to the vent with 4 built-in retainer clips. These clips make it easy to remove the screen for cleaning or maintenance. Just rotate the clips, and the screen will pop out.


The MaxxFan Plus vent fits standard 14" x 14" openings in the roof of an RV, camper, or enclosed trailer. A white interior trim piece (or garnish), insulated electrical connectors, and hardware are included for installation. The vent also has a molded-in mounting flange that is lined with a rubber weather seal, which helps prevent leaks. Roof sealant (sold separately) is required for installation.

To install, connect the two wires on the vent to your RV's electrical system. The black wire is for power, and the white wire is for ground. Then insert the MaxxFan Plus into the opening in the roof and mount the flange to the roof. To finish, trim the garnish as needed to fit the thickness of your roof and install it.

MaxxFan Plus With FanMate Cover

For extra rain protection, install a MaxxAir FanMate vent cover (sold separately) using the molded mounting tabs located on the flange. The tabs are designed to align with the integrated brackets on the FanMate, allowing for a no-drill, tool-free installation. These tabs also have rubber inserts that prevent water from seeping in under the flange.

Video Transcript for MaxxAir RV Vents and Fans - Roof Vent - MA00-04000K Review

Today we're going to be taking a look at the Max Air Max Fan trailer roof fit with a 12 volt fan. The reversible, variable speed fan is going to allow you to precisely control air movement in and out of your RV. This can be used as a ceiling fan. Basically, all you have to do is close the lid. This is designed to operate while the lid is closed and that's really going to help circulate air inside the trailer. There's a lot of neat features to this unit. You can see here it's got the rubber seal that goes around.

That's really going to help keep dirt and moisture out. It's just going to create a nice tight seal when that lid is closed. The other thing I want to point out is that you'll notice right here that this has a double left arm design. That's going to provide sturdy support for the lid when it's open. That's going to better withstand high winds without fluttering and it can remain fully open while you're driving. It's not a nice motor right here.

That's going to be a sealed ball bearing motor so that's built to last a long time. You got the wiring that's all nice and tucked out of the way. It's just a really nice design. It's going to have the clear fan blades. I believe this one is going to have a 12 inch diameter.

Really quick, we can just go ahead and count the blades to see how many it has. I'm going to start here at this brace so, 1, 2. 3, 4, 5, 6, 7, 8, 9, 10 so it's a 10 blade design. Again, the diameter of the fan is going to be 12 inches. We're going to go ahead and close it. There's a manual control knob underneath.

I'll show you what it is fully open. This is in the fully open position. With it installed on your trailer, with it fully open it's going to extend above the roof by about 11 7/8 of an inch, that's from the bottom of the flange to the top of the lid. In the fully closed position it's going to extend above the roof by about 3 3/4 of an inch. You can see here that the cover color is white. It does include the mounting flange and the interior trim piece or garnish. That's white in color as well. It's a nice, low profile design. Some other neat features about the unit, we'll go over these real quick. I'm going to go ahead and remove the interior trim piece. You're going to notice that on this side we're going to have that manual knob down here at the bottom. This is able to lock so the knob will lock to ensure that the lid stays in the position where you want it. It's got the indicators right there, so pull to unlock, open, close, push to lock. Then, right here we're going to have, this is just like a little touch dial. We have on and off. We have the little arrows right here that controls the direction that the fan spins so in or out. We also have auto. This is going to be a built in thermostat. Then we're going to have our plus and minus, which is going to allow us to adjust that thermostat in one degree increments. It's automatically or it's got an auto design at 78 degrees Fahrenheit. That built in thermostat is really a great feature. That's going to let you control the temperature inside your RV or trailer while you're away or at night time when you're sleeping. Ultimately, it's going to help save energy by running the fan no more than necessary. It's going to have the molded in white plastic flange. That's really going to help to prevent leaks. It's got all the pre-drilled holes. It also comes with all the installation hardware that's necessary for full installation. That's including all the different screws that you need to get it installed as well as the wiring connectors to run power to the fan. That key pad, it's a flush mounted design. It's very easy to use and it's very easy to clean. I also want to mention that it has an insect screen right here. That's going to be held in place with these retaining knobs. You just rotate those out of the way and then you can pop that screen out for removal or easy cleaning. This is designed to fit roofs 2 inches to 6 1/2 inches thick. Again, that interior trim piece or garnish is included. If you're installing in an application or on a roof that's less than 2 inches thick the ceiling must be built up. It does require 12 volt DC and minimum 5 amp service. It's designed to fit into a standard 14 inch by 14 inch or 14 1/4 by 14 1/4 inch rough opening size space. I also want to mention that it's a pretty standard size so the standard opening size makes it easy to replace or upgrade an old vent. That's one of the neat features about these. Again, white in color, overall nice, strong, durable design and everything you need to get it installed is included. That's going to do it for today's look at the Max Air Max Fan trailer roof vent.

MaxxFan Plus Roof Vent w/ 12V Fan and Thermostat - Manual Lift - 10 Speed - White - MA00-04000K

Average Customer Rating:  4.8 out of 5 stars   (181 Customer Reviews)

This manual-lift roof vent has a reversible, 10-speed fan and a thermostat to regulate airflow inside your RV, camper, or trailer. Ceiling fan mode circulates air when vent is closed. Removable bug screen keeps insects out.

Great fans. We boondock a lot so don't use the AC much, so two of these give it lots of airflow and keeps us pretty cool in our 21' TT. They have lots of air flow to clear out the heat in just a few minutes. They are totally silent on low and not very loud on high (Some say quieter than the Superfan). When we cook we reverse the flow to blow in and pressurize the odors and smoke out the hood vent and kitchen window. The only recommendation I have is to consider the one with the remote control. My wife is 5'0" and cannot reach the controls to open the vent nor turn it on/off. 544636

Still great.

This is my second purchase of this fan. The first one went away when I sold my van. My new van will be receiving this one. I was so satisfied with my previous MaxxFan that purchasing a second one was a no-brainer. Quiet and reliable with a number of useful features. Note the double brackets supporting the top, unlike other competing vents. This is my third purchase from etrailer. Their prices are great and shipping is fast. 546143

Super fast shipping and easy instillation. Fan works very well in a 6x10 cargo camper. Great product and customer service! 565572

- MA00-04000K

It’s a simple design, but works great. It’s reversible and has lots of speeds. The screen is easily removable for cleaning but locks in place. The lid is manual and the crank takes some getting used to but also locks in place and has been very reliable so far. Overall, for the price, this is a great fan. 732226

Works great quiet easy to install Wish my RV’s had places for more Like the temp setting and reversibility go to Death Valley a lot energy efficient have solar can Even leave on in storage if not worried about weather Need to get rain cover than no worries 728833

I have this very fan in my RV and it is beyond amazing! I am doing a rebuild for a friend and we are putting two in. one at the front and one at the back. that way one can push and the other pull and circulate the air even better! 726974

etrailer is GREAT! Haven't used the product yet but ordering & shipping was fast & efficient! I would much rather buy from these guys vs. the big "A" 695541

Just got it installed, works great! I had to do some modifications to the roof because I didn't pay attention to the 2 inch minimum, overall not a bad install process. etrailer was quick and had excellent service as always. 679299

Fan was better than the one we had in the RV. Only problem was trimming the sleeve to fit a 2 inch ceiling height. Shipping was quick and on time. 671064

We replaced a Fantastic Fan with this Maxxair 4000. It was fairly easy for my husband to install. We like the 10 speed feature. 661298

- MA00-04000K

I've had the fan in for a season, and a couple southern road trips. Generally happy. It will run "all night" with no problems on the stock dual batteries in my Ford Transit passenger van. Didn't spring for the remote and maybe would the next time. the controls are bit small, hard to reach, a touch confusing for groggy, middle of the night changes. Fan is quiet and efficient but even on high, directly over the bed, it's not going to bath you with sweat drying air movement. Quality seems good, I installed with an aftermarket, designed for the transit roof profile, ring, it went well. I painted the interior trim with gray "for plastic" rattle can paint to match the Transit ceiling and that is good stuff, it held up well to multiple on offs while getting the install just right". I also brush painted elastomeric white roof coating over the exterior caulk and and mounting screws, zero leaks so far. 641357

WOW.......what a fan!! Does everything it says it will DO. I especially like reversing to bring in fresh air. Will quickly exhaust hot or unpleasant air. Very quiet, even when on high. Great fan.... 556061

This fan is awesome, it moves a lot of air, installation was simple, replaced a regular gravity vent in my RV, obviously a Hugh improvement. Shipping was lightening fast from etrailer.com, and was reasonably priced, I would highly recommend them! 530138

- MA00-04000K

Awesome! No RV should be without at least 1 of these high flow fans. I have installed 2 different Maxxair models in my Reflection and love them both. I put the remote controlled model in the kitchen/living area where it is too high to reach the controls. Very well made fans. 527431

These fans are as awesome now as ever!

product came very quickly, everything was in great shape. the process for ordering went without a hitch. 525266

- MA00-04000K

Just what I wanted. Put it in the roof vent in the bedroom of my 5th wheel and really helps cool the trailer. 516574

Excellent addition to help keep the trailer cool.
Bob - 06/03/2019

I had used various AC fans and DC muffin fans to cool my 6 X 12 cargo/camper trailer. What a waste of time and money that was. I had figured that since I had such a small space, I would need less fan to keep it cool. If a 26 foot long 8 feet wide RV needed only one MaxxAir or Fantastic Fan, then a fan with half the power should work with my tiny trailer, right? Wrong! Don't waste your time with cheap fan. Get a real one that will move real air. I absolutely love the thermostat; it works extremely well at keeping the inside at a comfortable temperature. As the day heats up, the fan slowly ramps up- the hotter it get, the faster it spins. If it is only warm, the fan barely turns. Other fans with a thermostat will jam on at high speed, then shut completely off, then jam on again in a jarring, cyclic effort to maintain an even temperature. As the night cools down, my MaxxAir slowly ramps down to an idle so that I can't hear it which is nice when wanting quiet time for sleeping. Some time during the night it shuts off completely. When I sleep in, I'm not awoken by a loud fan kicking in. The thermostat mode is utilized almost exclusively. Whoever included this type of thermostat is a genius. Having the 10 speeds also helps tremendously at keeping a stable temperature and it does so with a quietness that is far and away better than any AC fan. Muffin fans are quiet, too, but they are anemic and won't work against any kind of breeze. The buttons and switches are easy and intuitive. Keep in mind the manual button and the thermostat button are completely separate from each other. Using the manual button will have no effect on the thermostat button and visa versa. Very efficient with electricity while having a ton of power. This is one of the best purchases I have ever made. Describing how well this fan works compared to other fans is hard to put into words. Very high quality and highly recommended. And a huge thumbs-up for etrailer's customer service. The only negative was not having a template. The installation took a lot longer sans template. This wasn't to replace an existing fan. This was a virgin install on a vertical wall with no help from anyone but my dog. 426744

This fan still remains one of the best purchases Ive made for my trailer. I cant talk highly enough about the quality, ease of use, and effectiveness of this fan.

- MA00-04000K

Etrailer shipped,very quickly. While researching which vent/fan I wanted to replace my old unit I used the advice function on the web site. The advice was quick and very useful. I looked at YouTube for installation instructions and was very happy to see the vent/used n the video was this unit. The video also gave me the confidence to do the instillation. The vent/fan was very easy to instal and works well. It is very quiet compared to the fan that came with my camper. I'm very happy with this vent/fan and etrailer. 292274

Ive only used the fan three times since I installed it. Im still very happy with the fan.

  • Troubleshooting MaxxAir Vent Powered Lid that Won't Open
    I've attached the owners manual for your 4900K model which is similar to the # MA00-04500K model. It sounds like your operator mechanism is bad according to my tech contact at MaxxAir. For your 4900K model you will want the Replacement Operator Mechanism for MaxxAir MaxxFan Plus or MaxxFan Deluxe Roof Vents # MA10-20281K-1AF. If you can't even manually lift the lid, this mechanism is definitely the issue.

  • How to Disable Rain Sensor Feature on MaxxAir MaxxFan RV Vent MA00-04500K
    It sounds like you have the MaxxAir MaxxFan RV Vent with rain sensor # MA00-04500K. This sensor consists of a small circuit board, which is shown in the linked photo. This could have failed, perhaps from damage from an impact from a tree branch or something like that. You can try turning this feature off. On the vent's keypad there is a button that allows you to disable the rain sensor feature. This is noted by an arrow in the second photo.

  • Replacement Circuit Board for MaxxAir Model 4751KSV05 Powered Vent Fan

  • Troubleshooting MaxxFan Plus Roof Vent
    According to the manufacturer's instructions three beeps and a green light on the MaxxFan Plus Roof Vent # MA00-04000K indicates you have entered Auto Mode so that all seems normal. However, if the light is on but the fan has stopped working that is most likely a sign that the circuit board has failed and needs to be replaced. For MaxxAir model 4000K you'd want to use Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents # MA10A21276K.

  • Recommended Fan-Tastic Vent Roof Vent With Fan For Quiet Operation
    For your vent with fan I recommend the Fan-Tastic Vent Roof Vent w/ 12V Fan and Remote - Powered Lift # FV807350. This fan has 13 speeds and has the ability to use the thermostat to conserve energy and automatically adjust for your needs. It also has a rain senor to close the dome when the sensor gets wet and resume when the sensor is dry. I've attached a video to assist. For a more economical option we have # FV802250 which has a manual lift vent and a fan with 3 speeds. This also...

  • Troubleshooting Maxxair Deluxe Fan That Starts and then Quits, Closes and Beeps Constantly
    It sounds like a circuit board issue. I recommend the Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents # MA10A21275K if you have a 4500K, 7000K, or 7500K model. If your model is a 4000K, 5100K, or 6200K then Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents # MA10A21276K is what you need.

  • Solution for MaxxFan Roof Lid that Stopped Opening with Switch
    Sounds like the lift motor needs to be replaced as it's no longer able to raise the vent lid. For that you'd want the part # MA10-20270. Since you are able to lift the lid manually it wouldn't be the operator. If this were the problem it would either make noise like you mentioned or wouldn't allow you to manually lift it.

  • Can the MaxxFan Trailer Roof Vent # MA00-04000K be Left Open Without Rain Getting Inside

If you are wanting a single-piece unit that includes a rain cover and utilizes a thermostat and a manual lift then the MaxxAir MaxxFan Trailer Roof Vent # MA00-06200K for Smoke or # MA00-05100K for White is exactly what you are looking for.

  • Recommended Vent Rain Cover for MaxxAir MaxxFan # MA00-04000K With Integrated Mounting Tabs
    For your MaxxAir MaxxFan Trailer Roof Vent w/ 12V Fan # MA00-04000K the recommended vent cover is the MaxxAir FanMate Rain Cover - White # MA00-955001. This is designed by the manufacturer to work with the integrated mounting tabs of the vent. I've attached a couple videos to assist. This will not only give you rain protection with full access to the fan and bug screen but also will restrict your airflow by less than 5 percent so you will be able to enjoy the vent.

  • Troubleshooting Remote Not Working with MaxxFan Plus Roof Vent # MA00-04000K
    If your MaxxFan Plus Roof Vent # MA00-04000K isn't responding at all to the remote then most likely it just needs to be replaced with part # MA00A01150K or the batteries are just in need of a change. I do also recommend verifying that you're able to adjust the speed settings and other controls by using the buttons on the vent itself to rule out the vent from being the issue. If you can't adjust anything using the vent buttons either then the remote is likely fine but a replacement...

  • MaxxFan Plus Roof Vent Cycles a Few Times After Vent is Closed
    If you have the MaxxFan Plus Roof Vent # MA00-04000K installed then it would make sense that the fan would continue to operate with the vent closed as this acts as a ceiling fan when the vent is closed.

  • Reversible MaxxAir FanMate Roof Vent In White
    For a white MaxxAir roof vent you would want the part # MA00-04000K. Then for a rain cover to fit this roof vent we have the part # MA00-955001. While the roof vent I recommended does not have the mounting tabs you mentioned it will fit the cover.

  • Replacement Switch for MaxxAir Roof Vent
    I recommend using a Circuit Tester like # PTW2993 to determine if the switch is bad or if the fan motor is bad. If you need to replace the wall switches, I recommend the Wall Remote Switch # VC0533-02-A. If you test the motor and the motor is bad, unfortunately the manufacturer doesn't have the replacement parts available so you will need to replace the entire unit with something like the MaxxAir MaxxFan Trailer Roof Vent w/ 12V Fan # MA00-04000K or further upgrade to the integrated...

  • Troubleshooting MaxxAir Fan Issue with New Motor
    It sounds like your MaxxAir MaxxFan Trailer Roof Vent has a powered lift like # MA00-04500K but has a connection issue. It is getting power for the lid to open and close but not for the fan function. I recommend testing your wiring using a circuit tester like # PTW2993 to make sure you are getting power to your fan switch and if so if power is getting to your new motor. If you test the motor with a battery and it works, then you know you have switches or wiring that is in need of...

  • Troubleshooting a MaxxFan Roof Vent Fan That Has Stopped Working
    Roof vents with fans like the MaxxFan Roof Vent w/ 12V Fan # MA00-04000K do not have a fuse anywhere in the fan itself. You will want to use a circuit tester like # PTW2993 to see if there is power getting to the fan. If it was installed by the manufacturer, there may be a circuit breaker that it is attached to, but most of the time they are directly wired to the 12V power. If there is power going to the switch, you may simply need to replace the switch and not the entire assembly....

  • Choosing High or Low Profile Powered Roof Vent for 2007 Casita Spirit Deluxe Travel Trailer
    The standard rough opening for a roof vent is 14-1/4 x 14-1/4, which is what you should have on your Casita Spirit Deluxe. Fantastic describes all their vent fans as high profile, but when closed they only sit 4-1/4 inches above the surface of the roof which is pretty typical for a powered vent fan, so 'high' is a relative term. Adding a Trailer Roof Vent Cover like # FVU1500BL would allow you to leave the vent open while towing the trailer. Otherwise, you'd need to make sure the vent...

  • Troubleshooting MaxxAir MaxxFan 12V Fan-Powered Trailer Roof Vent That Beeps
    My contact at MaxxAir advised that there are three potential causes for the beep and no fan motion you're experiencing with your MaxxFan Trailer Roof Vent # MA00-04000K. One potential cause is that the unit was wired with incorrect polarity. Make sure the white wire is grounded and the black wire is connected to your 12V power source (of at least 5-amps). Another possible reason for the malfunction is low incoming voltage. Use a voltmeter like # BTMT15 to make sure your battery is delivering...

  • Wiring Needed to Power MaxxAir MaxxFan Trailer Roof Vent From Trailer Battery
    If you were to run your MaxxAir MaxxFan Trailer Roof Vent w/ 12V Fan - Manual Lift - 14-1/4" x 14-1/4" - White # MA00-04000K off of a deep cycle battery you'd just need to run a power and ground wire from the battery to the vent motor and you'd be set. We have a bonded set of 12 gauge wire as part # 12-2-1 which you can run from the vent to the battery and you'll be set.

  • MaxxAir MaxxFan Trailer Roof Vent Operation Hours with Deep Cycle Battery
    The MaxxAir MaxxFan Trailer Roof Vent w/ 12V Fan - Manual Lift - 14-1/4" x 14-1/4" - White # MA00-04000K runs on 5 amps at 12V. I used a deep cycle battery calculator to determine that if this is the only thing running, it would take 74 hours of constant running to take your 625a deep cycle battery from a full charge to completely drained. I recommend using the Installation Kit # 344270KITW for this installation. I've attached a video to assist.

  • Troubleshooting No Power to MaxxFan RV Roof Vent MA00-04000K
    If you have tested the RV's power and ground wires leading to your MaxxFan Trailer Roof Vent # MA00-04000K and you have a full 12V of power reaching the vent's fan motor then there might be damage to the unit's control circuitry or the motor itself. If you apply a voltmeter like # BTMT15 to your power source wiring and you are not detecting a full 12 volts then it could be an issue with a depleted battery. This vent's motor draws 5-amps in use. If you have a spare battery known to...

  • How to Set a MaxxAir Vent to Blow Opposite Direction
    If the vent fan you have now is reversible then there should be a button on the assembly next to the other controls. However, if the fan is not reversible then all you need to do is reverse the wires on the motor (not the circuit board) and that will then allow the fan to blow air into the van.

  • Troubleshooting MaxxFan Roof Vent that Doesn't Want to Open
    Sounds like there's an issue with the linkage that raises and lowers the lid of the MaxxFan Plus Roof Vent w/ 12V Fan and Thermostat # MA00-04000K. If you can get on top of the 5th wheel I'd see if you can open the lid and check to see if the linkage arm that holds the lid has somehow been damaged.
