Let's go ahead and start with the lift mechanism, which is also called the operator mechanism for your MaxxFan Plus Roof Vent # MA00-04500K, which is faulty and why your fan won't stay open. For that we do offer the replacement:

Thanks Kyle The lift arm looks tweaked also on 1side. Could that b why it will not fully engage In open position? I will order the operator part u suggested if u think that is the issue instead. Do u have a suggestion for the seized set screw to remove fan blade to access parts to replace? Thanks

If the lift arm itself looks "tweaked" or somehow damaged, then I do recommend replacing that as well:

As for the seized screw, there really isn't much we can offer there other than home remedies like holding a screwdriver in place and trying to turn it slowly while hitting the back of the screwdriver with a hammer to create sort of an impact wrench.
