You dont say what all you have there. heat cool heatpump gas oil???????? With that O I think H/Pump
Now might be look in the blower unit .Should be a schematic there and see what color goes to what. I dont know what color you have for what. MOST MOST of the time R is power W is heat G is fan Y is compressor O is heat pump valve.
Black or a blue can be common???? AS I said look in the unit and see what is what first.

in my thermos doesn't have a green wire but in the unit it does
in my thermos i think the fan is a brown wire so i hook it too the G

ALso, you may of blown a fuse on the low voltage side if it's a newer system, if older, than may of blown the transformer.
