Williams 5008732 Fan Blade
The interior fan blade generates the flow of air from the wall unit. The fan blade also assists in keeping the heating or cooling system from overheating while it is running.
Subtle cues of a poorly performing fan
- The blade creates a grinding sound when it is spinning up
- The blade appears broken down or perhaps worn out and unusable
- The wall system can not blow good air as it tries to change the temp
