Is It Okay The Lid On MaxxAir 4400 Does Not Fully Open With Vent Cover Installed?

Question:

Hello I have MaxxAir 4400 rain sensing air vents on my 2021 Alpine 3910RK I bought the 955002 Black MaxxAir Fanmate vent covers. When on they do not allow the automatic vent cover to open fully. My question is this normal or did I purchase the wrong vent covers? Dave

Your MaxxAir 4400 on your 2021 Alpine 3910RK is still going to operate correctly even without the lid fully opening with the MaxxAir FanMate RV and Trailer Roof Vent Cover # MA00-955002. The lid on your fan only needs to open 50% to allow for the full circulation rating on your fan. You did select the correct vent cover for your fan.
