I installed this circuit board a couple years age. It was fairly easy to install and worked perfectly. I had no issues with it to date.

@FrankI A few years ago I also replaced the boards in both of my two MaxAir fans. Like you said, I found the process pretty straightforward. Every thing was fine until last summer when the two fans began to act up again. As long as I did not use the remotes and ran the fans manually on lower speeds all was fine. Kick up the speed or use a remote control and the fan would beep like before and shutdown. Very frustrating!

Hey Kerry, thanks for reaching out about this! The newer boards in the MaxxFan Deluxe Roof Vent w/ 12V Fan #MA00-05301K (also part #MA10A21276K for only the circuit board) are compatible with the higher voltage you referenced. I've actually…

Answer 8

I'll start off by saying that typically the flashing green lights on your MaxxFan #MA00-04000K means that there is some sort of voltage issue and even though when you tested you're getting what seems to be proper voltage, I would guess there…

It seems you are on the right track. The Replacement Printed Circuit Board #MA10A21276K will indeed be the correct replacement circuit board for your MaxxAir fan. Your serial number indicates the 5100K model fan, which is fairly common.
