Asked on Dec 29, 2011
I have question regarding problems I am having with the vent fan in a bathroom.
I have an older home that did not have a vent fan in the kids bathroom. Last year we added the vent fan, a NuTone 769RL. However, the bathroom (only about 10' X 7' in size) continues to steam-up when the shower is in use. I recently removed the fan to check for obstructions in the vent ductwork, as well as to ensure the flapper on the fan exhaust was functioning properly. All seemed OK. I even got my wet vac and blew air through the ductwork and got up on the roof and ensured it blew-through OK--which it did. Yet the vent fan just does not even begin to remove the steam/condensation. I even tried opening the window and door--and nothing seems to help. Any suggestions? It would seem that that size fan should be completely adequate for this size of bathroom.
