Replaces the printed circuit board and switch for your MaxxFan roof vents (MA00A04301K).


Replaced controller on Maxxair fan model 4301K when the fan would not turn off. etrailer supplied an updated board (the lower of the boards shown in photo). Board installation went smoothly and fan now operates like new.


Wasn't sure why my Maxxfan quit, but researched and took a chance by replacing the circuit board and switch. Thx etrailer the fan now purrs and cools. Great product and service.


This item was perfect. No issues, quick shipment, and described well. I actually made a youtube video on the install. Youtube channel Coolest Life.


Item as described and fast delivery, couldn’t be more pleased with purchase. The circuit board was bad in my RV fan and the replacement from e-trailer worked perfectly.

Great, easy to install and works perfectly.

Would have been nice to know the product was out of stock before I placed the order. It took almost a month to arrive, other than that, very good after sale service with the updated emails! A bit pricey for parts with the shipping, Amazon is faster and cheaper in most cases. But I will definitely order again.


Great replacement. Still runs great and easy to wire in.

Still working great!

I replaced the circuit board and the fan worked as should, so all good!


Perfect replacement for the faulty switch in my Airstream Nest roof fan. If you’re good with s screwdriver (11 screws total to access and replace the switch)


Unit arrived very quickly. Install was fine and unit then powered up normally.
The "only issue" I would put here is that they should also supply 4 nylon flat washers, (which there were none from the "factory install") 1, To space the pcb on the standoffs, so when installed, there is zero pressure from the switches on the label for the fan control. without those, to much pressure and the switches will poke thru the label. And 2, insulation for the metal screws that mount the pcb to the frame, so as to not short the redesigned pcb. About .20 cents.
But otherwise As advertised Fan now works!!


The circuit board assembly restored my MaxxAir 4300k to like new operation.

The MaxxAir fan has been wonderful and hoping this newer board design is more reliable than the old. In searching the web the old board design had some reliability issues. My board failed just outside of the warranty window. This design is supposed to be more robust. Very pleased to have the fan operating again.

Awesome! Still working great!

The new board resolved the issues, I added a buck converter to control max voltage, it would be better if the voltage regulation was built into the board. The Board by itself does not provide sufficient max voltage to be safe for RV use. Should provide for up to 24v Max voltage. Buck converter added $25 to the install.

Product was exact replacement. I did have to cut down the mounting posts on the frame about 1/16" of an inch so that the on/off buttons actuated when depressed through the plastic cover.


Perfect replacement for my failed MaxxFan circuit board. The old one failed, I think, due to moisture so I conformal coated this one before installation. I also put quick disconnect connectors on the power leads to make it easier to replace the next time.


Product arrived quickly. It worked perfectly. Really happy that I ordered from etrailer. Maxair fan switch quit working it was replaced works great now.

Still working great! Thanks

It took minutes to install the part and it worked perfectly. Thank you very much!


Exactly what I needed. Got here faster than expected!!


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


Awesome company. One call - help was right there from the moment Melissa picked up the phone. She found our product and was sent out. Husband put it in the camper today and it works great!!!! THANK YOU
