Whew! It's over a 100 degrees in this house. My blower will turn on but the outside compressor will not. I notice that I now have a loose yellow wire inside the Goodman furnace. This yellow wire comes from the Y terminal on the thermostat. It must be related to my problem, but I don't know what to wire it back to. It had to have come loose from a wire nut that was tieing the incoming thermostat wires to the Goodman receiver wires, but I don't know to what. Thank you for any help you can offer.

The yellow is one wire of the control circuit that turns on the AC compressor, if you haven't already , connect the yellow wire back on the Y terminal, and it should start the compressor.
