Hello. Yes we have had the same issue with our fan. The fan began to open and close on its own, or not open at all. Friends who have a van conversion told us this is a know issue with MaxxAir fans. The fix is to replace the circuit board but first applying a specialized silicon used for electronics to the board. There are lots of YouTube videos detailing how to do this. The caveat is to be careful in taping off the parts of the board that should not have the silicon applied. We used a spray can of the silicon, our friends used the kind that is brushed on-probably doesn’t matter which kind is used. Regardless, the silicon is fairly expensive. We did that and it has worked so far. We also had the lift mechanism shatter, and we replaced that. Finally, the remote quit working and we replaced that as well. We use the fan all the time; it’s a great fan, just requires a fair amount of maintenance.
