What is this gadget for? It goes in the vacuum line that controls the heated air inlet door. I've been playing with it while I'm waiting for a chance to sand and paint the air cleaner. When I apply vacuum to the large (white) side, equal vacuum appears on the small side, but if I then release the vacuum on the large side, the small-side vacuum slowly leaks down to zero. Is this thing just a "screen door closer" for the heated air inlet door, to keep it from slamming shut?
The white side says "SENSOR" on it. I guess that is to remind me that the white side goes toward the temperature sensor instead of toward the inlet door.
