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.

Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents w/ Reversible Fan - MA10A21275K

Average Customer Rating:  4.5 out of 5 stars   (177 Customer Reviews)

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.

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:

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:

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:

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:

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:

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



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:

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:

I purchased from e trailer but had to go the manufacturer for replacement of faulty unit. If there is next time I will go direct to them.



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:

basically would not talk to me to have this item returned, wasted nearly $[XX] !! ive bought from etrailer several times, wont be back



by:

The replacement part solved my issue. What else can I say. It was an easy install.



by:

I have ordered multiple items from etrailer in the past and have always been satisfied with their product quality and fast shipping. I highly recommend etrailer.



by:

The part was delivered quickly in good shape. I followed youtube videos to install it and its working fine for the last year.



by:

Works. Circuit board did not look the same as the original, but still worked as advertised.
Unhappy about the price!



by:

Product was easy to replace and went right in, works flawlessly.



by:

Worked like a charm. Direct replacement.



by:

Called customer service, gave them the model number, they gave me the part number and price, and they shipped it within a hour and a half. They even emailed me when it was delivered. Who can ask for more. Best experience I’ve ever had.



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.

Carol;
Thank you for the prompt email
regarding the circuit board replacement for my MaxxAir Roof Vent. I must say that etrailer customer service has been fantastic with regards to this item. I completely understand that the lengthy delay in obtaining the item was the fault of MaxxAir and not etrailer. Your customer service regularly kept me informed of the manufacturer's shipping progress and it was very much appreciated. Anytime in the past I have ordered from etrailer I have received excellent service and this time was no exception. Thank you and your team again for the outstanding customer service.
Sincerely,
Roman

I am NOT a happy camper! MAXXAIR roof vents are a piece of crap. Three times now I have had to replace the circuit boards and they still do not work. Correction, they work for a short while then stop. E trailer experts were great, you put me in direct contact with Maxxair and they were helpful but their productcircuit boards are simply crap. From the looks of the large number of similar complaints. I am not the only persons complaining. I would NEVER RECOMEND MAXXAIR to anyone.

  • Troubleshooting A MaxxAir MaxxFan That No Longer Works After Replacing The Rain Sensor
    If swapping out the rain sensor caused your fan to complete stop working I would first double check that no fuses were tripped and that the fan is getting a full 12v DC power to properly operate. If it is then the issue is going to be with your circuit board # MA10A21275K and you'll need to replace it.

    If your MaxxFan Plus Roof Vent w/ 12V Fan, Thermostat, and Remote - Powered Lift - 10 Speed - Smoke # MA00-04500K is only functioning at one setting and not allowing you to control anything else then the circuit board is the most likely cause.

  • Troubleshooting A Maxxair Fan 3540K Automatic That Won't Stop After Closing Lid
    I spoke with the manufacturer and based on your issue the gears are most likely stripped out and can't sense that its reached the end so you'll need the Replacement Lift Motor for Maxx Fan Plus Roof Vent # MA10-20270. If this doesn't solve your issue then the next step would be to replace the circuit board with the Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents w/ Reversible Fan # MA10A21275K.

  • Will The Replacement Keypad For MaxxFan Deluxe Work With The MaxxFan Plus?
    Yes, the Replacement Keypad for MaxxFan Deluxe Roof Vent # MA10-21304K will work with your MaxxFan Plus # MA99FR since the MaxxFan # MA00-07500K & # MA00-07000K use the same circuit board # MA10A21275K.

  • Lid Won't Open on MaxxFan 7500K Deluxe Roof Vent Fan
    If the lid no longer opens or closes even when using the manual knob then that means the operator mechanism is bad which is rather common to have to replace. The part you'll need for this is the Replacement Operator Mechanism for MaxxAir MaxxFan Plus or MaxxFan Deluxe Roof Vents part # MA10-20281K-1AF. If the lid no longer opens with the controls then that could mean either a bad operator mechanism or a bad lift motor and in which case you'd need the 10-20270 part # MA10-20270. I don't...

  • Troubleshooting a MaxxFan 7500 That Keeps Closing On Its Own
    I contacted the manufacturer regarding the issue you are describing with your MaxxFan Deluxe Roof Vent w/ 12V Fan # MA00-07500K. They recommended first doing a reset on the fan. You can do this by removing power by pulling the fuse from the circuit the fan is on from the fuse box. Then reinsert the fuse to do a reset on the fan. If you continue to have the same issue, they said that he circuit board is likely having amperage issues and would need to be replaced. The correct circuit board...

  • Replacement PUAN_4700 Circuit Board For a MaxxAir Vent Fan
    We do ship to Canada! Typically when you get those flashing green lights, it is because of a voltage issue. I would use a volt meter like the Digital Multimeter # PT89ZR to ensure you are getting the proper voltage. If you are then I would assume there is a short on the circuit that is causing the problem. The correct replacement circuit board will depend on whether you have a MaxxAir fan that is a manual lift or powered lift. Manual Lift - Replacement Printed Circuit Board for MaxxAir...

    Your MaxxFan Plus Roof Vent w/ 12V Fan and Thermostat - Manual Lift - 10 Speed - White # MA00-04000K could be cutting off after 10 seconds for the following reasons: 1. Insufficient or fluctuating power. Your fan could be receiving less than 12v of power. Check the power wire at the unit using a multimeter like # PT89ZR. If you aren't receiving 12v then you could have a voltage drop off due to the length of the wire running from the battery to the fan and would just need to increase the...

    Since your MaxAir MaxxFan Roof Vent # MA00-04500K has power to it but the fan is not working there is one of two possible issues. One is that the rain sensor is detecting moisture keeping the fan from working. Cleaning the sensor with Isopropyl Rubbing Alcohol should dry up the moisture, but if not you will need to replace the rain sensor with the # MA34FR.

  • Troubleshooting MaxxFan 04500k That Beeps and Closes
    In the past when we've presented similar issues to MaxxFan they've recommended unplugging the fan from it's power source, waiting a few seconds, and then plugging it back in to reset it. Typically that will clear out any errors in the board. If that does not work it would be time for a new circuit board which we offer with the # MA10A21275K for your # MA00-04500K.
