Damper operation on Model 688
How do I know the damper is operating properly on Model 688 series fans? I just cleaned both of mine, and the dampers seemed immovable. Is there a special release that is triggered when the motor assembly is in place?
It turns out both dampers were stuck. With a little gentle force at the bottom of the damper, both popped open. I cleaned both damper flaps and they are operating fine now. Lesson is to clean more often, and check damper operation every time you clean.
