Thermostat wires running from house to outside Kenmore AC unit were chewed by dog. Got replacement wire. Took panel off. There were three encased wires running into AC unit that were chewed. Only see...
If you have a central air conditioner, or a split system, where the indoor unit is attached to the furnace and a outdoor unit is located outside of the home. 2 copper lines will be connected to it, a larger and a smaller one. If it is a air conditioner and not a heat pump, the A/C usually uses 2 wires, that are connected. Allot of times a installer will use a 3 wire thermostat wire, to run to the outdoor unit, if this is the case, the third wire will be folded back out of the way.
The color of the wire is usually picked by the installer, I myself usually use white and red and fold the green out of the way. If you only had 2 wires hooked to it to start with, it really would not make a differace which one you hook up to either one of the yellow wires.
All you are doing it having one wire coming in and one wire leaving,,,, just creating a complete circuit, just don't connect the two yellow wires together.
Example: If you have 2 yellow wires on the A/C unit and 2 wires coming from the house "example a red and a white" hook the white to "One yellow wire" and the red wire to "the other yellow wire".
You are just creating a complete circuit, when the thermostat calls for cooling, it creates a magnetic pull and closes the contact points, in the air conditioner, outside, this allows the 220 volt to flow to the compressor,,, and ahhhh cooling!
I hope I have not confused you, I am just starting to help on this site and still trying to make things understandable.
Wish you the best,
