    You have now 220 volts? Or 24 volts? Does the unit run if you push in the contactor?

    Is probably low voltage prob. Check the smaller tstat wire going to the contactor,for 24 volts.trace the wire back to the furnace if you don`t have 24 volts, looking for chewed or broken wires. Have you checked the circuit board for a blown automotive type push-in fuse
    Let us know what you find

    Sounds to me like you have got a wire put in the wrong place either on the contactor or the capacitor.
