LG LCU340CP Fan Blade
The fan blade generates the stream of filtered air away from the heating or cooling system. The blade also pulls air in which contributes to making the whole system cool while running.
Subtle hints your primary fan blade has little life left
- The fan blade subjects you to a weird noise when turned on
- The fan in the wall unit has issues when it tries to generate a good airflow as it tries to make the room more comfortable
- The fan blade looks cracked or maybe beat up and in sad shape
