My a/c a carrier unit blower will not shut off unless I switch breaker off. I opened the unit and found a burnt mark on the circuit board hk61ga001a the coil on the circuit board has a burnt hole in it. I replaced it with a icm272. The outside unit comes on, but the blower will not. I jumped a switch on the blower housing (has about 6 wires, purple, blue, black etc.) the blower came on, but would not shut off till turned breaker off
