can fan blades in a small house type fan go flat?
I have a fan going in a room on low for air circulation, and never gets turned off.. it's 1 of the wire framed 1's with the aluminum fan blades. been on since probably may..went to clean it earlier today and realised. it no longer blew air except out the sides but it was more like whipping the air from spinning.. held paper to the back and it has 0 suction.. this fan was nearly new and working great when I turned it on in may.. I know it's just a house fan but it's got me scratching my head.. could the blades have flattened out from the constant rotation?
