Replaces the printed circuit board for your MaxxAir MaxxFan Plus roof vent. Works with models 4751KS, 4761KS, and 4951KS.Get a screwdriver, an extra set of hands, watch a video, pull the fuse, and take a photo of the wires before you pull them apart.
I was hesitant to order because the new board has different components than the old, but it works great, and all functions were preserved. Photo shows new board with tag and part number next to the old board (from a maxxfan 4751ks) for comparison.
And it’s your trailer. You can break it if you want to and fix it twice, and buy a few new tools for less than the shop will charge. You got this!
A perfect replacement PCB for my MaxxAir fan board that quit working. Shipping was faster than originally expected. Replacement was simple and my fan is working like new again.
This product didn't work. etrailer refused to refund and instead told me to contact the manufacturer who told me to contact the seller.
Waste of money and time. I just ended making my own set up with a momentary switch, a dimmer, and a directional switch.
Great customer service too!

Its working great. I did spray the circuit board with silicone modified conformation spray to give the boards components and waterproof coating. I believe the original board got damp from constant rainy weather and it short circuited. The spray aint cheap but you tube DIY types really recommended doing this.
exact replacement and very easy to inst all.

great, no problems with this product after a year
It was the exact part I needed to fix my MaxxFan Roof Vent. Thanks, again etrailer.
Reasonable cost and easy installation. My only concern is the fact that the part was shipped in bubble wrap in a small envelope. I wouldn't advise this shipping method in the future.
Great customer service. The part was easily installed and the vent is now working as intended.
Exact fit, and fixed our broken MaxxAir.
Nice quality. I ordered this item to have one on hand in case of a failure. So far I haven't needed to install it but I'm sure it will work well.
The items came a day earlier than expected and packaged well.
Installed the circuit board and the fan works again. It was an easy install also.
Great customer service. Quick shipping and had parts I had issues finding on other suppliers websites.
Works like a charm

Great
Working and full time Rv living in the north I get a lot of condensation and it fries my MaxxFan boards. These boards are amazing replacements. Easy installation. I do spray them with electrical sealer before install to keep them from getting zapped again.
Not sure why this unit be packaged in an envelope as it is delicate product package look beat up tossed around as us mail delivered.
Still working great in the camper for the MaxxFan Control Board.
Easy to change out from broken one. I believe it was 5 days from order to home.
I was very impressed with Service quality, speed of the shipping and handling. This greatly reduce my downtime for a very important bathroom vent fan that stopped working.
Fit perfectly and worked correctly when installed. Good product.
This part has been in place for one year and continues to work as it should!
Had a bad relay on the old circuit board. Replaced the board with this new version and it works great
The team was very knowledgeable and helpful. And the turn around time to ship the order was outstanding!
Easy replacement, works as expected.
The part worked
Although it is slightly different in appearance than the original, it is direct replacement for a 4 speed, with power lift, and remote control MaxxAir Deluxe

It’s been a year since purchasing a replacement PC board for my Maxxair fan and wanted to provide an update. It’s still working great. We’ve used it now for two trips this new camping season and it’s still working great. I’m glad E-trailer carried these and was able to just the replace the circuit board and not the whole fan.
