Found a single MD10TU and 10 inch duct without a fan behind it insufficient to adequately compensate for an 800 CMF vent fan.
The damper stays in the open, (powered) position with the vent fan off with no back draft issue present. A replacement pressure switch in on the way.. John528. North Little Rock, AR, USA. 2016-08-26 19:10:26
