Friedrich CP12 Fan Blade
The interior fan blade helps establish a nice flow of air from the system. The fan blade also helps out with keeping the wall unit cooled down whilst working.
Easy warnings of a declining circulating fan blade
- The main fan blade appears to be chipped or wrecked and should be replaced
- The fan in the wall unit has difficulties trying to blow enough air to change the temp in the room
- The air circulating blade subjects you to a very unhealthy sound when it starts to turn
