Carrier 42D Cooling Fan Blade
The blade attached to the fan motor for the main outdoor unit has a main function of scattering the heat energy that is released by the compressor. Most fan blades are rugged, but sometimes they may not hold up from time to time for reasons involving humans, animals or even nature itself.
Simple indications of an ineffective fan blade
- Edges of the blade are fragmented or beat up for some reason
- It looks rusty and maybe dented from being outdoors
- It is out of balance as it begins spinning and trying to cool the compressor
