There will be two wires in the unit. The low voltage wires (white and red) attach one to each of the wires in the control box on the unit. There will be a wiring diagram on the inside of the ac unit access panel. Shut the power off first. Also, after you hook them back up, it may still not work. It is possible that the control fuse blew on the indoor unit. For a step by step troubleshooting guide, check out my source.
Hi, Always fun to work with electric. Take a look at the wires that you have. You should have the wires that come out of the condenser and then the wires that go to the condenser from your circuit box. White will usually go to white and red to red/black which depending on age of wiring can be the same. This being the case your white should go to white and the red should go to red/black. This should bring power to your unit. If you plan to keep doing this sort of work a mid-range electrical tester really helps especially telling you if something is still live and able to zap you...
what you have is a thermostat wire it is a two wire so if one is not connected and the other one is wire the ones that are not connect together regardless of color. wire manufacturers vary their wire color but the all work the same make sure to tape it up after you do it so it don't fry your transformer in the a/c unit..follow the blue wire to contactor on the opposite side of where it hooks up there should be another wire follow it and you will see where it is broken twist that wire to the one that is unhooked then put the wire nuts back on
Do you have two whites and two reds? If so connect the whites together, and connect the reds together.
The wires you describe control the relay that starts the AC unit. The main power wires are heavy duty (black and red if this is a 220 volt unit). The light guage wires are low voltage AC and connect to the thermostat. DO NOT joint the red and white wires. There will be a terminal for the red wire. You will have to find out which one it is. Try to get the wiring diagram for your unit from the Internet or call a service professional.
