OK my central heater blower will not come on at all when on auto, and when on manual/on it just blows cool air out of vents. I was told to put a jumper wire on (w) to (g)wires at the thermostat, (I think) to check it, but not sure exactly. Is that the thermostat on wall or what? The pilot light is lit, but doesn't seem to be lighting up anything when turned on man. Also the pilot light is a orangeish looking flame, is that OK if it's a propane heater? I appreciate all the help I can get on this prob with as much detail as possible because I'm doing the work myself and I haven't got any experience with the electrical part of ac/heater operations, thanks again for any assistance
