One of the best companies I have ever ordered from. Knowledgeable, helpful and keep in contact after the sale. All helpful for do it yourselfers.
by:
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!

The parts ordered did the trick and now my MaxAir fan is working again. I started to give 4 stars instead of 5 due to delivery issues. After I thought about it I can’t blame etrailer for the delay. I was informed they had received the order, the parts were in stock, when the shipping label was generated and so on. The delay sits squarely on USPS, looking at the tracking my parts sat in Atlanta for 4 days for no apparent reason. Anyway, l installed the parts and all is good. I have ordered several items from etrailer and have been very pleased with them.
by:
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.

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.

by:
Almost plug and play. Needed to take the surround off the fan to access the house (trailer) wiring to properly connect the black and white wires, the rest were plug and play. I could have taken the easy way out and cut the old wires, trimmed the new black and white ones short, and used wire nuts to attach to the house wiring. Not as pretty as what I did, but it would work.
by:
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.

@Joel sealing the circuit board is a great idea for this and other parts, I'll have to keep that in mind. Thanks for sharing!
by:
For a moment I was a bit apprehensive, since the new circuit board was missing nearly half the components of the original one, but after hooking it up and testing it out I found that it worked perfectly and I am very satisfied with my purchase. This component replaced the original circuit board on my Maxx Air fan in my camper.

Good service and parts came in on time Will be ordering more parts soon
by:
Just what I needed to repair my RV’s MAAXFAN! It seems to be an updated version of the original circuit board, too, as their are fewer components on the board. Shipping was quicker than expected & installation was straightforward. This is only the second time I’ve ordered from etrailer I HIGHLY recommend them!
by:
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.
by:
The board was an exact match of the OEM board. Replacement is fairly straightforward; however, there is a little maneuvering of the wiring in our set up due to the amount of the wiring that needed to be tucked in around the vent surround. So far, all is working as it should with the new boar in place. Gwen from the customer service team was very helpful in locating the correct replacement board and putting in motion my order!
by:
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.
by:
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.
by:
Circuit board arrived on time and my fan worked properly after installation. Etrailer customer service was great and verified part number I needed before I ordered it.
by:
exact replacement and very easy to install.

great, no problems with this product after a year

by:
It was the exact part I needed to fix my MaxxFan Roof Vent. Thanks, again etrailer.
by:
looked different than the original circuit board, however all plugs fit and used existing wire nuts
and all worked. Yea!!
by:
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
by:
Item order went smooth, fast shipping and item as described, Thanks
by:
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.
by:
Part was a direct replacement and fixed my problem.

  • Replacement Parts For a MaxxAir MaxxFan Deluxe 8951K
    We do not carry an exact replacement unit for the MaxxAir Deluxe 8951K. We have the Smoke # MA00-07500K or White # MA00-07000K which would be the closest replacement. These fans use the same lift and fan motors but the control panels and circuit boards are going to be different so you would not be able to swap all the parts. Here are the replacement parts for your fan if you want to try changing out certain components. Also be sure to first check the power going to the fan as if the voltage...

  • Troubleshooting A MaxxAir MaxxFan That Keeps Turning Off
    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...

  • MaxxFan Model 4751KS Will Not Shut Off
    I took a look at your order and saw you had purchased the Replacement Key Wall Control part # MA00A03550K but the issue you are having with your MaxxFan Model 4751KS is the circuit board, the Replacement Circuit Board part # MA10A04751KS so this what you need to replace.

  • Why Won't My MaxxAir MaxxFan Shut Off? Wall Control and Circuit Board Troubleshooting
    Hey Alan, Yes, either the wall control or circuit board could be causing your MaxxAir fan to run continuously. I see you just ordered the Replacement Wall Control # MA00A03550K, so hopefully that solves it! In the meantime, here are a few things I'd check: Reset the fan: Turn off its 12V power at the fuse or breaker for about a minute, then restore power and see if the controls respond normally. Check the control cable: Remove the wall control and make sure the RJ-11 connector is fully...

  • Replacement Circuit Board For A MaxxAir MaxxFan RV Roof Vent
    Hi James, The INC115342 part number you gave me unfortunately doesn't come back to anything. Do you know what the model number of your vent is? If not the boards will typically have a tiny white sticker on them with some info that I could use to look for a replacement. If you want to send me some pictures of the current circuit board I'd be happy to take a look.

  • Replacement Operator Mechanism for MaxxAir MaxxFan 4751KS
    The correct Replacement Operator Mechanism for your model 4751KS MaxxAir MaxxFan is part # MA10-20281K-1AF. If your fan lid is unable to open even manually, then this is the part you need to replace. The other part you referenced, # MA10A04751KS would replace the printed circuit board on your MaxxFan instead. If you aren't sure which part needs to be replaced on your MaxxFan, let me know what issues you're having with it and I'll be happy to point you in the right direction.

  • Correct Replacement Circuit Board for a MaxxAir 4951KSC Roof Vent
    All the "C" stands for in the 4951-KSC part number has to do with the "Clear" aspect of your fan.

  • Troubleshooting A MaxxAir RV Roof Vent That's Opening Too Far And Closing On Its Own
    Hey Mike, I wouldn't rule out some moisture in the air being enough to trip the sensor and close the vent overnight but if you're saying that the motor is still running after the lid is fully open then that could be an indication that the control board is faulty. Before replacing it you should check the voltage at the power wire for the unit. If you take down the inner shroud you should be able to see the wiring and can then test it with a multimeter. RV vents can act goofy if they aren't...

  • MaxxFan 2016 Keystone Montana Model 3710FL Won't Stop Running
    If your MaxxFan with the rain sensor, like part # MA00-04500K, starts operating automatically and the controller or the controls on the unit aren't working then that sounds like a bad circuit board or that the built-in safety feature for too much (or not enough) voltage was activated and the circuit board locked up. Since you already removed power from the vent try connecting it back to power. If it works properly then it was just locked up and needed to be disconnected from power to unlock...

    Based on the issue you are having, Yes. A bad circuit board can cause all kinds of weird issues like your fan running all the time and the vent lid not opening.

  • Troubleshooting A MaxxFan Plus 4751KS That Won't Shut Off
    Hi Albert, If the vent isn't turning off when pressing the off button on the keypad then then either the keypad # MA94YR or circuit board # MA10A04751KS are malfunctioning and would need to be replaced. I'd start with the keypad first since it's the lower cost item to replace. In the meantime you can either remove the garnish and disconnect the wiring or pull the fuse to prevent the fan from draining the battery.

We do not have a generic picture, the pictures on the product page are the ones we took of the actual part in hand. According to MaxxAir, the # MA10A04751KS replaces the 10A04751KS and 10B04751KS.
