Haier ESA408M Fan Blade
The motor spins the blade which helps establish the flow of air from your HVAC wall unit. Along with blowing air out, it also takes air in which contributes to keeping the heating or cooling system cool and not overheated while it is heating or cooling.
Signals the circulating fan blade is going to die
- The unit blade produces a disturbing sound while slowing down
- The main fan blade looks bent or worn out and probably should be replaced
- The wall unit can not circulate a large amount of air as it tries to make the room more comfortable
