Any zoning AC Aggie gurus on here?
I've learned more about AC zoning in the last week that I've ever thought possible. I'm actively doing trouble shooting of a hot zone. I replaced a damper motor a few days ago, and just now realized the reason my downstairs zone is getting hot is no air coming from the vents.
I replaced this motor exactly how it was previously installed. I'm wondering if this damn thing was installed backwards? I'm going to do some more testing today and see if I get air flow with the damper in the "closed" position.
The bypass damper's counter weight rusted off, but I manually closed that damper about 80%. But would a malfunctioning bypass damper keep me from getting any air in my downstairs zone? I didn't want to close it 100% to allow relief for some static pressure....but I'm wondering if I should close the bypass up completely so I can get full air in my other zones?
