Williams 1403621 Fan Blade
The fan blade assists in creating the flow of indoor air that was cooled or heated by your system. Along with blowing air out, it also takes air in which helps in making the unit cooled down whilst working.
Hints your fan will have to be replaced
- The blade makes a squeaking sound when turning it off
- The blade looks chipped or broken in a way
- The fan in the wall unit refuses to circulate a large amount of air to make any difference in the room
