Video Transcript for Review of Maxxair RV Vent and Fan Parts - Operator Mechanism - MA10-20281K-3CF

Ellen: Hey everyone, I'm Ellen here at Today we're taking a quick look at the replacement Maxxair roof vent manual lift operator. This is going to fit several different models of the Maxxair roof vents including some deluxe and standard models. It does have the list of part numbers that this fits in the description on our product page here at, so definitely check that out.But basically, this is going to allow our handle in our enclosed trailer or an RV to turn that lifting mechanism to lift up our vent. That way we can let in some air, get some circulation going and keep everything nice and cool, let out the hot air, let in the good cold air and vice versa. If your vent or fan is cracked or damaged at all and you've got some water leakage, it's probably best to just replace the entire unit.

But if everything's working properly, and this is really the only issue is that it's just not lifting or closing anymore, this is going to be a much less expensive option as far as keeping everything working and instead of having to replace your entire unit, you can just replace this small mechanism to get everything working again.But if anything's damaged like your top cover's cracked, you're starting to get some leakage in there, you probably will want to just replace that whole vent unit because it's important to keep out any kind of water damage from your trailer. You don't want to get anything else inside your enclosed trailer dirty or anything like that or damaged. We have a lot of options available here at, if you want to pick one up. But that aside, if everything else is working just fine, this is definitely going to be an easy way to replace that and get you back out on the road, enjoying the cool air.It is an aluminum construction. It comes with that mounting hardware.

We'll have the two bolts and nuts that capture inside there to mount this in place. And then it'll also have the two holes to attach it into our system. The distance between those two at the bottom is about two and five-eights of an inch, center-on-center. The length of each of those hexagonal sides is about a quarter of an inch for each of those hexes. And then the length coming off here is about one and three-eights of an inch.

The instructions do have a list again, of what this is going to fit and then instructions for the various different models and how to get those taken out and replaced, so it makes it a little easier to do your install without having to do any guesswork.But that's going to do it for our look at the replacement Maxxair roof vent manual lift operator.

Replaces the manual lift operator for your MaxxAir roof vents with manual lid operation.


I ordered this product and as always, etrailer was very quick to get it delivered! I haven’t installed it yet, to be able to talk about the workmanship of the part. But they were very quick getting me the part!



It’s been a year and this is still working just like day 1. No more issues. It was fairly easy to install also, nice plus.


This worked perfectly as a replacement lift operator mechanism for my MaxxAir 4401k Maxxfan ventfan with manual open and close knob in my 2017 Flagstaff Micro-Lite.

One day the knob on my vent fan would just keep spinning without opening the vent cover. This part was what was needed to fix the issue. When I went to replace this part I found that my original lift operator was split into two pieces. Not sure how that can happen when all it is lifting is a plastic vent fan cover that weighs next to nothing, but apparently this is a common problem after searching on-line.

In order to install the lift operator it was a combination of working inside the trailer and from up on top of the roof. I was hoping to be able to do it all from inside, but it seemed much easier to do most of the work from up top.

The part came with instructions that were good, but it took me a few tries to get the right combination of where the knob on the lift operator needed to be set initially and how to position the existing lift bar that connects to the vent cover after replacing the lift operator mechanism. The instructions did indicate what position the lift operator needed to be in, but that didn't seem to work for me.

It took me about an hour from start to finish to install, but now that I have done it once I could probably do it in a few minutes.


Perfect fit replacement part, fair price, fast shipping and the BEST customer service in the industry!


Easy to understand website to find the part we needed. Quick shipping and tracking was very accurate


I did not expect instructions to come with it.but it was a great help


Excellent customer service, talked to actual friendly and helpful humans who sent me the correct part promptly. Five stars.



One year in, the part I ordered and the resulting repair have been highly successful.


Ordered this part for a friend. Waiting to hear back on the installation.
It arrived on time as promised through the postal service. Good job etrailer.


Still working good after 1 year.


Worked perfect....



No problems.Still works perfect and I use it a lot.


Easy install and allows the fan to open and close again with ease. Shipping was quick.


It worked great, and is still working g reat!


The service was fast and accurate, the part was exactly what I needed. Thank you.


Direct replacement part. Easy to install in less than an hour.


Good product replacement fast delivery


Fantastic! This part worked perfectly and was a snap to install. Just what I needed.


Mechanism worked fine, installation was difficult as previous mechanism was flush mount to bracket. This replacement lift operator had screw heads that protruded. I was able to modify the mounting bracket to accept the screw heads and enable flush mount.
4 stars due to modifications required.



One year later and all good. Mechanism continues to function properly.


I think the service I always get from eTrailer is phenomenal. I generally do not complain about products and eTrailer cannot be blamed for carrying extremely low quality repair parts by manufacturer’s like MaxxAir. The MaxxAir roof vent manual lift operator is a shoddily made piece of garbage but it is necessary for the operation of the vent. At approximately $40 MaxxAir should be ashamed for the poor quality because I know few people who haven’t had this part self destruct. I would happily pay $100 for a duplicate part if it were machined from steel or aluminum. With the stress put on the mechanism by the spring which is part of the overall lift mechanism, pot metal castings are not going to hold up. It is only a matter of time until every one of these mechanisms will fail and need to be replaced.


Exact replacement part and easy to install.
price point as well.


etrailer was super easy to access and order the replacement part for my broken (again) Maxxfan. They shipped the part immediately and delivery was quicker than expected, so quick I was able to make the repair before up coming camping trip! This is my first time using etrailer, they were great, I highly recommend. This is my 3rd time replacing this part, I am very dissatisfied with Maxxfan!


Fit perfect and was the fix for my Maxxair fan that wouldn’t open. Piece of mind getting this from Etrailer.


Certainly much better assembly than original unit!


Product fit perfectly and installed easily, vent works as it should. Old one came out in pieces and was only a couple of years old. Hopefully, this one is more durable.


It works correctly as described, easy installation and fast delivery. Would highly recommend.


Very quick service/delivery. Have not yet installed, so I can't comment on quality of the product.


All was as expected

  • Installation of MaxxAir Replacement Lift Operator
    When installing the # MA10-20281K-1AF replacement operator, you might need to 'clock' the mechanism slightly which could take a little bit of trial and error, but the replacement operator does include installation instructions.

  • Recommended Replacement Manual Lift Operator For A MaxxFan 5100
    To replace the manual lift operator on your MaxxFan Delux 5100 series, you will need the # MA10-20281K-3CF. This will be a direct replacement and will get you back up and running in no time. I will also mention that sometimes the actual lift arm can also get stripped out, so you may also need the # MA10-20222KS, which is also a direct replacement. This is less likely to be an issue, but it never hurts to plan for the worst and hope for the best.

    If the dome on your MaxxAir # MA00-04002K vent fan will not open with the manual knob then the MaxxAir # MA10-20281K-3CF "operator" is broken and should be replaced.
