Frigidaire LRA257ST21 Fan Blade
The fan blade produces the stream of filtered air away from the heating or cooling system. Along with blowing air out, it also takes air in which helps out with keeping the unit cool and not overheated while it is working.
Simple signals your primary fan blade will need replacing
- The fan blade makes a disturbing sound when it starts to turn
- The blade looks cracked or maybe wavy and probably should be replaced
- The fan in the wall unit refuses to circulate enough air in order to achieve the proper temperature
