I can always depend on ETrailer for having the correct parts and materials that I need to maintain my RV or other trailers.



by:

The product is a replacement (that had broken 2 of the 3 spokes going down the road 15K miles) for one with a smoke colored lid. This one should keep the temperature down a bit in the sun. Don't know if it will be any stronger than the first one. The service from eTrailer was outstanding!



by:

Perfect replacement for the fan we couldn't reach in the bathroom.



by:

Disappointed after placing my order (over$[XX]) the items went on sale and etrailer would not honor the lower sale price for my order still in transit.



by:

It is a very good unit but needed to adapt it to a different brand of fan connection so had to order power cable.



by:

After installation the RV was totaled in Hurricane Ian, so we never had a chance to use this item after installing it. Installation went well however, but that’s all I can comment on.



by:

Love it works great. Easy to install.

@Louise Great, gotta keep those critters out!!

Works great!



by:

It’s taken me a bit to install due to unforgiving weather. But everything with the fan was fantastic! So easy to take out old and replace with new. No need for instructions it’s already tagged for u. Device on ordering and receiving was quick and easy. I hope I don’t have to replace for a long time, but if I do I will definitely order from E trailer!



by:

Exact replacement. Easy install. Excellent value.



by:

Received my order quicker than expected. Josh was extremely helpful, courteous and professional. When and if I ever need parts again for my RV, etrailer will be my first choice! Thank you Josh!



by:

5 star service and order follow-ups. There were Supply chain issues due to COVID but they kept me informed along the way. They even followed up to make sure items arrived ok. We'll done and thank you for caring!

Works Great in our 5th wheel. It really moves the air and this allows us to cool the living area without the noisy AC. The customer support that we received when ordering it really came through!



by:

package delivered on time. I have used etrailer in the past for parts and have nothing but great things to say about them.



by:

Just what I needed. Came in two days. Why everyone thinks [online vendor] is the answer to everything is beyond me.

Thanks! We have been wondering the same thing!

Thank you!

Very fast shipping. Great product!

Exactly as shown. Just what I needed to replace an existing unit.



by:

Customer Service is top notch! Tracking is easy and reliable. This company really goes the extra mile. Personal service with product quality.

The fan is the same one that I needed to replace.
I installed the exhaust fan and it works great!



by:

The customer service at etrailer is second to none. Fast shipping, high quality gear. I love these guys.



by:

Very easy to order and efficiently delivered, Will keep them as an excellent resource.



by:

Great product exactly what I ordered. Each other had it to me in two days great customer service



by:

Its awesome. I just wish I would have known that my order didn't include the remote so I was unable to operated it until I paid $20 extra for remote for each fan



by:

Need to make sure you order the switch and cable.

  • Replacement Lid For A MaxxAir MaxxFan 4951KS
    For your MaxxAir 4951KS the correct replacement lid is the Replacement Lid for MaxxFan and MaxxFan Plus Roof Vents part # MA10A40009K (smoke) or part # MA10A40002K (white). The shape of the lid is slightly less rounded as your current lid but it will still fit the same.

  • Replacement Circuit Board For A MaxxAir MaxxFan In A 2021 Grand Design Solitude 3540 5th Wheel
    Since multiple MaxxAir Fans have the same features that you listed it's honestly best to first determine the exact model number you have before purchasing anything and end up not having it be compatible. I've listed below all the available circuit boards for the each model, if you have a tag on the vent listing the model number then we can identify the correct replacement. If not, you'll need to pull the circuit board and find the sticker on it that lists the model number. Once I have either...

  • MaxxFan Roof Vent w/ 12V Fan in White Versus Smoke
    The MaxxFan Roof Vent w/ 12V Fan - Manual Lift - 4 Speed - Smoke # MA00A04401K can have the cover replaced with a white one using # MA10A40002K. This is the closest option to clear. If you want a powered lift you can alternatively use the MaxxAir MaxxFan Plus Roof Vent w/ 12V Fan - Powered Lift - 4 Speed - White # MA00-04751KSX which will use the same replacement lid.

  • How High does the MaxxAir MaxxFan Plus Roof Vent part # MA00-04751KSX Stick up off the Roof?
    The MaxxAir MaxxFan Plus Roof Vent part # MA00-04751KSX will be 3.25 inches over the roof line of your trailer when installed. To ensure proper installation I recommend using the Roof Vent Installation Kit part # 344270KITW. This will have all of the sealant and screws that you will need to make your vent water tight and ready for use after just a short drying period. I linked a video showing an installation.

  • Can RV Vent Hook up to Existing Wiring
    Vent fans are two-wire designs so they are much less complicated than air conditioning units. They only have a 12 volt wire and ground wire so you just need to be able to attach the 12 volt to a power source and have a good ground and that's all there is to it. To install them you will need the Roof Vent Installation Kit # 344270KITW and for extra wire if needed the 16-Gauge # DW02359-1, which is sold by the foot. For fans, so long as you have the standard 14" x 14" opening, which you...

  • Troubleshooting MaxxFan Not Opening on 2017 Grand Design Reflection
    It looks like you have the MaxxAir MaxxFan Plus Roof Vent w/ 12V Fan - Powered Lift - 4 Speed - White # MA00-04751KSX. The unit sounds like it is malfunctioning and this could be due to the rain sensor # MA34FR. It sounds to me like the sensor is seeing moisture whether there or not and keeping the power lid from opening. I recommend unplugging the rain sensor and seeing if all the other functions work. If so, then simply replace that sensor. If the other features still do not work,...

  • Will The MaxxAir II RV and Trailer Roof Vent Cover # MA86JR Fit a 2022 Tiffin Phaeton 37BH?
    The MaxxAir II RV and Trailer Roof Vent Cover # MA86JR is designed to attach to the mounting tabs on the top of most MaxxAir fans like the MaxxFan # MA00-04751KSX. As I have no way to see exactly what fans were installed on your 2022 Tiffin Phaeton 37BH you will need to see if your fans have the same style clips these covers were designed to fit. The covers also include mounting brackets to fit other fan manufacturers which sounds like the issue your friend had. This could likely be resolved...

  • Do RV Roof Vents with Rain Sensors Draw Power All the Time
    RV roof vents like the Replacement MaxxFan Plus 4-Speed Roof Vent with White Lid # MA00-04751KSX that you referenced do not draw power when they are off and the rain switch is active. Basically the rain sensor is a switch and when water on the sensor completes the circuit the switch activates and then the lid closes. It's no different from how when a light is switched off and there is current present at the switch there isn't parasitic amperage draw. So with this light setup you would...

  • Is There RV Roof Vent Option with Wall Mount Controller
    I have a solution that I think would work well for you but all of the roof vents we offer for RVs do use either remotes or controllers on the assembly itself. The MaxxFan Plus Roof Vent # MA00-04500K though comes with a wall mount for the remote though so you could leave the remote in the wall mount and you'd basically have a wall mount controller. If you check out the picture I attached you can see the remote being held in the wall mount.

  • Recommended Sidewall Powered RV Vent For A Camper Van Build
    While the Replacement MaxxFan Plus 4-Speed Roof Vent with White Lid # MA00-04751KSX isn't designed to be mounted on the side an RV, anything is technically possibly with a little bit of redneck engineering. That being said the lid and the arms that hold it up are plastic and would probably be too fragile to withstand driving at highways speeds facing the incorrect way. This would probably end up costing you a fortune in replacement parts over time so you'd be better off with something...

  • Correct Replacement For A MaxxFan 00-04951KSCX
    I am afraid we do not carry the exact model fan 00-04951KSCX that you are looking for. We do have the MaxxAir # MA00-04751KSX which is a very similar MaxxFan Plus Roof Vent. This will be a suitable replacement for your vent, if you are looking to replace it.

  • MaxxAir Roof Vent for RV that is Compatible with Wall Control Unit
    If you have the wall control part # MA00A03550K installed in the wall of your trailer the Maxxair Fan part # MA00-04751KSX would easily integrate into it and work great. If you have a different switch setup let me know and I'll see what options you may have.

  • Roof Vent With Variable Speed Fan, Powered Lift and No Thermostat for RV

  • Correct Replacement For A MaxxFan 4951KS
    Yes you are correct the Replacement MaxxFan Plus 4-Speed Roof Vent with White Lid # MA00-04751KSX is the right replacement and measures 18 1/8" long and 16 1/2" wide, which is the same measurements as your current MaxxFan Plus Roof Vent w/ 12V Fan, Thermostat, and Remote # MA00-04500K.

  • Troubleshooting A MaxxAir Fan That Randomly Turns On With The Keypad Disconnected
    If your MaxxFan Plus 4-Speed Roof Vent with White Lid # MA00-04751KSX isn't lifting electronically or manually then your lift arm or operator # MA10-20281K-1AF is most likely broken and would need to be replaced. The gear inside these are notorious for breaking so the knob is most likely just spinning inside the broken gear. If the fan is kicking on without the keypad connected then the motor is somehow getting power to it activating it. These fans typically get tied in with the wiring...

  • Can A Powered Lift Vent Function On An RV Roof Vent Be Wired To A Switch For Activation
    The switch on your wall is only turning the power on and off for the fan. With a powered lift there wouldn't really be a way to tap into the function and wire it to a switch to make it easier to access. The only option would be to replace the current vent with one that has a remote to activate the lift function, like the MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-07500K. There are also certain models (MaxxFan Plus: 4751KS or 4951KS and MaxxFan Deluxe 8751K or 8951K that can use wall mounted...

  • Do you Carry a Fan that will Both Intake and Exhaust Air for my Roof Vent?
    I have a great solution for you but the MaxxAir MaxxFan Plus Roof Vent w/ 12V Fan part # MA00-04751KSX does not function as a in and out type of fan instead use the MaxxFan Plus Roof Vent w/ 12V Fan and Thermostat part # MA00-04000K this will give you some additional features like a thermostat if you want to set it to come on when the temperature dictates. Of course it is also reversible at the touch of a button simply choose what way you want the air to go. This one also has 10 speeds...
