I have an Ameristar Air conditioner unit in the back yard that has three wires that run to the unit in the top rear left hand corner if your looking from the top. The other conduit runs here as well. I was told that these wires are from the thermostat and that its not a difficult fix. My 100 lb. lab/pit mix ate them as well as my dish wires that were run across the back of the house. Is this a simple fix? What can I do?

Yes,, simple fix,, 1st pull the pups teeth out, lol
The wires are color coded,, cut out the chewed part and splice back together, example ,red to red,, yellow to yellow, blue to blue or what ever the colors are, and hope that the wires didn`t short together and blow the transformer

Good luck
