the power being furnished by transformer is not enough. Connect contactor and go inside air handler and measure the output of the 24 volt xfme. If it is good start looking for broken wire. If there is a spare wire move over to it.

If it is a 110 unit,use a regular wall receptacle ,if it is a 220 unit,use a 220 receptacle for 220 it will be made larger and different.Draw a picture of the plug on the end of the cord and go to the hardware store and get them to help you i d the plug.some 110 units are 40 amp,and are a little different than the regular 110 house hold 20 amp receptacle.
