Hi I'm Brian and I'm here to help! The part number you provided is for a cased evaporator coil. These usually sit atop a gas or oil furnace. If the contactor in your outdoor ac unit is not getting 24 volts, it could be one of many things e.g. drain overflow switch, thermostat, chewed low voltage wire, low voltage fuse, etc... The transformer in a system with a furnace, an a-coil above and an ac unit outside is located in the furnace. If you can remove the blower panel (lower panel on an upflow furnace) the model number for the furnace should be inside on the side of the furnace cabinet. I can give you much better info with make and model number of furnace. Thanks,Brian
