Troubleshooting MaxxAir 7500 Stops Working and Flashes Green
Updated 09/29/2025 | Published 09/01/2025
Question:
I have a Maxxair 7500 fan. Over the weekend, it stopped working. When i turn it on, the vent lid opens and the fan begins to spin momentarily, then lid closes, fan stops and then beep and flashing green light starts. I have tried multiple times to cut power and restart, but same sequence every time. Any advice on how to fix this? Thanks, Tim

Hi Tim; between the behavior you're describing, the steps you already took, and the beeping/green flashing light I would say the board needs to be replaced. The Replacement Printed Circuit Board for MaxxAir Powered Lift RV Roof Vents # MA10A21275K is the correct part for your 7500.
