Jeff: Hello, everybody. This is Jeff at etrailer.com. Today, we're going to take a look at the Replacement Printed Circuit Board and the Switch for the MaxxFan Roof Vents. Now, this part will replace the printed circuit board and the switch on the MaxxFan Roof Vents. Part number FA00A043401K. It will also work with the models 4201KW, 4251KW, or the 4401KW.
If you notice it has the 2-pin plug-in connector on this one, and then two wire pigtails right here, a black and a white wire. But that should do it for the review on the Replacement Printed Circuit Board and Switch for the MaxxFan Roof Vents..
My MaxxFan would only work on high speed (that let me know that the motor was still good). Changed the circuit board and now everything is to good in my world (until the next thing breaks)
Easy to identify and order. Item installed and tested as a perfect replacement for the older design card.
This circuit board installed easily and works better than the original. The program remembers the selected fan speed when you turn it off, so you don't have to start at low and step up to high speed. Very satisfied.
Product was a perfect replacement for my faulty fan control and saved me from having to buy a new toilet exhaust fan. Very satisfied
Thank you
I held my nose and paid a ridiculous price for this poorly designed piece of junk - something the seller likely imported for under $5. At the time etrailer.com was the only source. Now that the "supply chain issue" era is over etrailer.com and other vendors are selling the same part for a better price. It's been almost 2 calendar years (well outside the 60 day return window) but in my case that amounted to less than 200 hours of runtime before it failed. The poor design is regarding thermal management. Before it completely failed I took the whole thing apart to troubleshoot intermittent non-operation, and noticed that the components on the board were too hot to touch. That's an indication there should have been a heat sink involved or that the components used were under-rated. Given the cost and complexity of replacing the whole fan unit I'm pretty much stuck with buying another one of these delicate flowers. I'll try drilling some holes nearby to see if extra ventilation helps.
New circuit board for Maxxfan. Better design works perfectly.
Product arrived quickly. It worked perfectly. Really happy that I ordered from etrailer. Maxair fan switch quit working it was replaced works great now.

Part was good, worked properly, easy to install. I thought the price was a bit excessive for such a simple electronic device. It was difficult to find but maybe that explains the price
Item was the right part for the repair
It did not solve the problem. Sometimes the vent runs fine. Other times, it still stops running at random times.
I was assured by the experts at E Trailer that the replacement 4 speed switch offered for my Maxx fan would work even though it it was not quite the same circuit board as the original ( which failed after only a few operations) in my Winnebago RV..The item was delivered in good condition and installed the next day...It works perfectly!...Thankyou
Perfect fit. Easy install.

The circuit board is working as advertised. No issues.
Super easy to install and it's been working without any issues for over a year now.
I am very impressed with how promptly you shipped my item. It arrived today just as you said it would.
Thank you
Bought this as a "fix" to my Maxx fan stopping every minute. Now it stops very 5 minutes. Was not the fix I need, I guess. Will be looking for another fan.
Great service, friendly customer support,fast delivery.
direct replacement for original, works perfectly

Still working one year later!
It was the right part and arrived in good time. Still working a year later.
Easy to order with the professional guidance of the parts personal, they found the part number for me and help order it. Thanks
Customer service was helpful in finding the correct part for my MaxxFan. They shipped the board out the same day I placed the order and I received it in just a couple of days. I would recommend purchasing from them again.
I ordered this part over the phone with Joshua's help.
