Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents

This is the second item that I"ve ordered that has arrived with damage. The prongs for the touch pad connection were all bent almost 4o degrees to the side and one of the electrical components was also bent over the edge of the board. It was shipped in a thin bubble envelope that offered no protection! This item deserved a box and adequate padding to ensure its interity. Worst of all it did not solve the issue with the fan! I will continue to find the cause of the failure and let you know if this board failed because of the damage. I suspect it is a voltage issue that the manufacturer has failed to address properly.1657356

I am sorry to hear that it arrived damaged. I will have our Customer Service team reach out to you.

This circuit board did the trick and brought a dead Maxxair fan back to life. I was thrilled with the price, the quick shipping, and communication from etrailer folks through the whole process. I was also please to see the recent manufacture date on the board, which hopefully indicates I won't run into any of the issues that plagued the original board.1669438

Hi.Pleased to report that after 1 year the fan is still working perfectly.I would just like to mention that prior to installing the new circuit board I used an ink pen type applicator to seal it with a conformal coating.I decided to do this after seeing an on-line tutorial that suggested the failure of the original board may have been due to moisture.The fan worked fine for the first 5 years so it may be too early to know if the conformal coating is helping or not.

@Howard Please keep in touch and let us know how it works!

etrailer did its job well. They got the right part shipped right away, and were johnny on the spot as regards to communications about my purchase and the shipping details. Alas, the replacement circuit board did not rectify the issues I'm having with my fan. This is not an etrailer issue, it's a MaxxAir issue.1661268

Part worked perfect. I bought this as I was getting intermittent green blinking light followed by a loss of power. This happened after I went to a lithium battery. As others have said, the volts are higher and older models are said to not like volts over 12.8 or so. I hooked it up. Was very easy to do. And, ran it for about 2 hours. Ran it on all speeds and also changed directions. No issues. I'm going on a 4500 mile trip. So, that'll be the real test! If I have issues I'll re post.1626540

I was bummed about having to replace the circuit board on my MaxxAir fan and finally conceded that I'd spring for the part.
I chose etrailer.com because their price was the best. Once on the phone with Joanne, I quickly realized that she could handle my concerns about whether this new board would solve the problems of the old board. She answered my questions, gave me some confidence in the outcome, and was polite, personable, and professional.
Joanne K. Followed up with an estimated delivery date which was accurate. Today I received the board, installed it, and it solved the problem! Joanne K. Is the best!1556096

Easy install, fixed problem immediately. Definitely suggest testing your fan motor before ordering to narrow down any problems to circuit board.1651620

The price I paid for this part, at least it should include the plastic keyboard that the circuit board mounts to. I like value and it feels like this company is nickel and diming me on this product.1641073

The circuit board was easy to install using the provided instructions and it still works like new.1613769

I was getting the green light of death on my max air fan. It would run on low speed ok, but when I increased the fan speed it would stop and the light would flash green. So I would have to cut the power to reset the fan, then it would work on low speed but I got the flashing green light. So I saw that many had changed the circus board to fix the problem. I found the circuit board on e trailer, changed it today. It seems to be fixed. I let the fan run for about two hours today on a higher speed and it ran the hole time. E trailer got the part to me fast. I’m very happy that it worked for me.1533200

Took about 15 minutes to install and works perfectly. Ordered March 2022 with anticipated delivery date of October 2022, so was happy to receive it in July 2022.1321775

The fan is still working perfectly one year later.

etrailer provided terrific customer service by getting us the needed part quickly and by providing access to a technician who could answer our questions regarding troubleshooting (to determine which part was needed) quick and easily.1580630

Website was easy to navigate. Shipping was fast. The part was the correct one and fit perfectly1604362

Took awhile to ship. But worth the wait for a direct replacement for my Maxxair vent.1197802

Controller for Maxxair is still performing well.

Our Maxxfan had a flashing green light and beeping from the unit. Thanks to your on line trouble shooting help, it told us when you have this issue, you need to replace the circuit board. Again, through your online help info, it told us the part number the circuit board we needed for our 4000k Maxxfan. I paid for faster shipping and received the circuit board in 2 days. The extra shipping fee was worth the price. The circuit board was easy to replace and we are up and running again. This fan is in our bedroom and we use it constantly when we RV. A very happy customer!876668
