Replacement for MaxxAir 10B04751KS Circuit Board

Updated 10/30/2025 | Published 02/10/2025

Question:

I need to order Maxxfan part 10B04751KS and realize your number is different, MA10A04751KSI am good with that however, the part I need does NOT look like the picture on your site for the same . I have attached a picture of the one I need. Was there a design change? is your picture generic? I own a mobile Rv repair and have been struggling with this. Your pic and mine are attached. Thanks

Hi Randall; MaxxAir is on the third version of this circuit board so it is no surprise the pictures look a little different. I'm sure they have improved on the design each time while maintaining functionality for older replacements. 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. If you take a look at the picture I attached you will see where another customer had the same design as your picture from a MaxxFan 4951KS. They ordered and successfully replaced it with the # MA10A04751KS.

Hey Randall, did the # MA10A04751KS end up working as a replacement for your MaxxFan board? Knowing how the updated version fit could really help others dealing with the same design change.
