Kitchen Vent Blower

Hello,
I have a Thermador remote blower (see attached picture). From time to time, the 2 plastic flappers remain open. I've replaced with OEM flapper which by the way comes with tiny spring mechanism. Is there any way to upgrade these flappers to be more dependable and tighter seal so I don't have cold drafts coming into the kitchen? I am tempted to stop using the fan and cover up this area with foam board to avoid cold air. Thanks in advance!
