Video Transcript for Review of Maxxair RV Vents and Fans - Enclosed Trailer Parts - MA10A21275K

Michael: Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at the replacement printed circuit boards for your max air powered lift RV roof vents. As you can see, we've got two different boards here. These are the part numbers that you see on the screen there. Essentially, these are exactly the same thing with one small difference between them.

If you look at the circuit board, you can see they have almost all of the same components except this large black box here. This is actually going to allow you to work. Allows this board to work for your max air vents that are both exhaust and intake. So this other one that does not have that box is only going to work with your max air fans that are exhaust only. If your unit is able to bring air in as well as exhaust it out, you're going to need this one over here.If your unit is only capable of exhausting the air from inside your RV, this is the unit that you will need here.

Keep those part numbers up there for you to make sure that you are getting the right one. It's a pretty slight difference between them, but obviously it's going to have a big impact on their usability. We want to make sure that you're getting the product that you need, so just wanting to clear that up for you. Both of them are going to work with your max air power. It's just that functionality difference that you need to look out for.

We're going to make sure that you knew the difference and are going to get the right chip that is going to work for you. That is going to complete our look at the max air replacement printed circuit board. Again, I'm Michael with etrailer.com. Thanks for watching.

Replaces the printed circuit board for your MaxxFan RV roof vent with powered lift and reversible fan. Works with both aftermarket and OEM models of MaxxFan Plus and MaxxFan Deluxe manufactured after 2010.

I replaced the PCB on my Maxxfan when it would only work on one speed and only exhaust. But when I put the new PCB it didn’t change anything. With further research, I discovered it was the moisture sensor and not the PCB. But, now I have a spare part for my fan. This company is an amazing company and really great with everything they carry



by:

Replace a circuit board on my MaxxAir Powered Lift RV roof vent fan. The circuit board fit perfectly. Watch several videos on how to replace the circuit board. Had the job done in about 45 minutes. Hardest part of the job was getting all the wires hidden.



by:

One of the two circuit boards we purchased to replace faulting circuit boards on our Maxx air fan has also started to fault. The other is functioning just fine. This is very frustrating.



by:

I would have given 5 stars but the circuit board had some damage to it and was doubtful it would work but it worked just fine.

I know that it is working for you however I am concerned that it had some damage since it is an electrical unit. I will have our Customer Service team reach out to you.

Circuit board is still working perfectly.



by:

It appears that the circuit board, once sealed against moisture, has been a fix. I also added a regulator upstream of the board to keep the voltage at 12 volts or below. These fans do NOT tolerate voltage fluctuations.



by:

Product is as advertised. Only concern is that one of the components (yellow square piece, see photo) on the control board looks to be bent over as a result of the shipping process in soft materials. I have straightened it out by hand and am hoping everything works once installed. Otherwise clear communication and great customer service.



by:

etrailer was exceptional as always with their quick ship. Got the board installed and fan is working again. After a lot of research I also installed a voltage regulator so hopefully this new board doesn't get fried again when we use our solar. Maxxair should be ashamed of themselves for selling fans that were not designed to handle the higher voltages of solar considering most RVs come with solar prep. A suggestion to etrailer would be to put some type of warning on your page for these Maxxair fans about this known issue and also offer a 12V regulator like the DROK DC-DC Stabilizer, 9V-36V to 12V regulator to install with these fans. A $17 regulator to protect a $160 board & $120 motor; a no brainer to me.



by:

Circuit board works perfectly! Sade a ton of money doing it myself.
Customer service rep Kimberly O was extremely knowledgeable and helpful.



by:

I received exactly the part I needed and it has worked perfectly for the year I’ve had it installed. As usual with everything I’ve ordered from etrailer shipping was fast and the product was quality.



by:

Giving this two stars because the price is absolutely ridiculous for what it is... especially since MaxxAir should have applied a conformal coating on these from the start thereby never needing to even have this part in such high demand. This part costs almost as much as a whole new one. Absurd for a product that typically fails due to manufacturer incompetence. I reached out to MaxxAir before buying this and even though the board failed due to a manufacturer defect, they wouldn't help me. Giving it two stars instead of just 1 because while the price is a total rip off, it does work.



by:

I think I got scammed from Amazon. I purchased 2 max fans & held them until my roof on my rv was done. Now the warranty is up one fan works and the other did the green light death thing. Brand new and it doesn’t work. This replacement works very well a bit high priced but what can I do with a 350 fan with a bad controller. It was shipped very fast and works perfectly. The manufacturer should be giving discounts to offset the price of repairs. Thank you for having the part and fast shipping.



by:

Etrailer service was 5 star. MaxxAir part worked but didn’t fix the problem of the fan beeping & shutting off. Decided to bypass the board and wired a reverse polarity variable speed switch directly to the fan. Works fine now. I just lost the automatic lid closure function, which is no big deal.



by:

Product shipped and was delivered quickly and on time. It was a direct replacement and easy to install.



by:

After I finally got it in it worked as it should. The hardest part was getting it in with all the wires in a small area. Lots of fitting then moving then fitting again. Then success.



by:

After we figured out what the problem with our MaxxFan was, we ordered the part and it arrived soon after ordering. We installed the new circuit board and that cleared up our problem.



by:

The circuit boards don't last more than 11/2 to 2 years. Very disappointed.



by:

Easy install, fixed my fan in kitchen and have had no issues since. Super happy with.



by:

Looks and works great

by:

Easy to change out and works perfectly!



by:
