It sounds like a circuit board issue. I recommend the Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents # MA10A21275K if you have a 4500K, 7000K, or 7500K model.

If your model is a 4000K, 5100K, or 6200K then Replacement Printed Circuit Board for MaxxAir Manual Lift RV Roof Vents # MA10A21276K is what you need.

It sounds like your rain sensor itself. I would try replacing it and see what happens. We've had reviews in the past were people had the same issue and that was the fix. The part you will need is # MA34FR
