ActronAir Indoor Fan Capacitor 20uF P2 with Cover is the run capacitor for 750W-class ActronAir indoor fan motors including the 9x9 S 750W and 9x7 S 750W deck assemblies that require 20uF for correct single-phase operation. The 20uF rating is the highest in the P2-with-cover indoor fan capacitor range -- fitting this capacitor on a motor requiring a lower value will cause the motor to draw excess starting current and may damage the indoor PCB's motor circuit. Isolate power at mains before replacing any capacitor components.
