Hi I have a Goodman Furnace GMP 100-5 with an AC connected to it. How should the wireing be connected to the furnace. It does not work when we turn on the heat. Currently the furnace has a brown wire coming out with 5 wires which is connected to the brown wire from the AC unit. The furnace also has a yellow, white, brown, and green wire hanging out. The thermostate brown wire has 5 wires and the yellow wire is connected to the red wire on the AC wiring and the red wire is connected to the brown furnace red, the green wire is connected to the green wire coming out of the furnace. The other 2 wires white and blue are not connected to anthing.What is the proper way this should be wired?
