I just bought a 2005 Wildwood 26'. Everything seems to works fine. When I am plugged into shore power, I hear a slight humming sound coming from the panel beneath the fuse box in the bathroom. I am wondering if this is a fan to cool it or if there may be a problem. Pictures of the fuse box on top and the panel (which I can't get into.) on bottom.
Just to be sure, you should somehow check to see if you have airflow. Maybe you can hold a small ribbon of tissue in front and check for air movement. Depending on the humming noise, it could be a stuck fan in the converter.
