The HVAC Genius 40+5 uf MFD 370/440 Volt Dual Run Capacitor 40/5/440R Condenser Straight Cool/Heat Pump Air Conditioner

Original had 3 wires coming from the capac instead of three labeled spade connectors. two red, one brown. brown to b, 1 red to c. any wiring help?

My furnace makes a big hum when starting the blower motor. Could the problem be a weak capacitor?

Product description says 45+5 mfd, picture shows 50+5 mfd. which is it?

Can i replace my old capacitor wilspec ca370-05v with this. it's 5micron f +-5% ?
