Friedrich SH20L30-B Fan Blade
The interior fan blade generates movement air from your HVAC wall unit. The fan blade also helps out with making the whole system cool and not overheated while it is performing its duty.
What to see if the primary fan blade is about to go out?
- The unit blade looks cracked or maybe marred and in very bad shape
- The blade produces a disturbing sound when it starts out
- The fan blade refuses to blow a large amount of air as it tries to change the temp
