Friedrich EM18 Fan Blade
The interior fan blade helps establish movement air that was heated or cooled by the unit. Along with blowing air out, it also takes air in which aids in keeping the wall unit from overheating while it is in operation.
Major clues the circulating fan blade needs replacing ASAP
- The wall unit fan blade looks ruined or maybe worn in some way
- The air circulating blade causes a terrible sound when turning it off
- The wall unit does not circulate a large amount of air to make any difference in the room
