I replaced my Dual Capacitor as per instructions. Yellow to Herm. Blue to common. Brown to fan. Now my fan runs backwards. Is it possible that they wired my a/c incorrectly from the install. It is almost 5 years old, and never been serviced. It is possible that the wires I disconnected from the capacitor were on the wrong way, indicating that the wiring was wrong from the install. Should I switch any of the wires to right the direction of the fan?

Take at at these diagrams. Let me know which one you are using. Replacing the cap should not reverse the motor.
