Friedrich WS10B30A Fan Blade
The fan blade assists in creating the movement of air that was heated or cooled by the unit. The fan blade also draws air inside of the unit which assists in keeping the wall unit cool and not overheated while it is performing its duty.
Major signs your fan blade is in dire straights
- The blade subjects you to a terrible sound and causes discomfort
- The system refuses to blow a large amount of air to change the temp in the room
- The wall unit fan blade looks shattered or perhaps beat up and should be replaced
