5 ton carrier. we changed the condenser motor and marked where the wires connected. Old motor had yellow and brown to capacitor. New motor has an extra brown wire with white stripe... I connected it the same way as the old one without using the extra wire.... didn't work. Advise how to connect the new 5 wire motor... red and black wires I'm confident are connected correctly.


The best way to wire that motor is to connect a separate capacitor to it. The brown and brown w/white stripe go to the capacitor. The black and red wires go to the contactor. ... Air Conditioners
