After only four years of ownership, our MAXXFAN has completely stopped working. Pressing the power button does absolutely nothing and the fan doesn't even try to rotate. So, of course, this became a DIY repair job I just had to tackle myself.

Just like most DIY jobs on RV appliances, diagnosing and repairing a MAXXAIR exhaust fan is a very straightforward and easy project. Most handymen with simple tools on hand can complete this project in a couple hours.

It turns out our MAXXFAN failed because of excess moisture buildup on the control board causing terminals to corrode completely away. This is extremely frustrating considering most exhaust fans like this are installed directly over the shower like ours is. However, I came up with a solution to this problem that results in my new control board being water resistant to avoid this issue in the future!

Check out the video below for a full stepbystep guide on how to diagnose a nonworking MAXXFAN RV exhaust fan, as well as how to apply a safe and nonconducting water resistant coating to the new control board!
