The master-bath bathroom vent is stuck open. During the winter cold air streams down and makes the bathroom very cold. The guest-bath doesn't do this and seems to be working properly.
Where is the flapper valve on this thing? Is it on the bottom where the electric fan is? Or, is the flapper on the top where a simple pipe comes out of the roof? It has to have a way to keep air from flowing back down the pipe.
