While I was moving my thermostat , two wires crossed and a small spark happened.
My blower out side is working but attic unit stopped working. This is unit is 1.5 ton from Weather king. What could go wrong with Red and White wires touching while moving the thormostate?
:o

What color wires do you have? Chances are that you have a loose connection on the "G" terminal, or not wired correctly.
