@gixxtrixx Only G and Y should be jumpered, and only if it's not an electric furnace. In furnaces run by fossil fuels, you can jumper the G and the Y on furnace level, but do not jumper the G and the W.
If you need the fan to turn on with the heat (not the AC), I suppose you need to jumper the furnace terminals G & W instead of G & Y, is this correct? Please respond if there are any issues with this method. Thanks for posting this.
Thanks for putting this video together. It is great. However, I have an issue. I have an oil furnace in my basement, and an air conditioning system in my attic. My G wire is connected to the air conditioning system in the attic. I looked in my air conditioning system, and I don't have a C terminal in there. I have the following terminals in the unit in my attic: R, W3, W2, W1, G, 3. And there are currently wires connected to R, G, and 3. Can you help?
Note for users, if you use this G wire for the C, you will not have a separate Fan control when you throw the fan switch. Most people never use the separate fan switch anyway but note when you throw the fan switch, no fan will work as a stand alone fan as you have removed the wire from the fan screw "G".
@optical76 You missed my point. I am trying to advise you that the fan will ONLY work when the furnace or the air conditioning turns on. The fan switch has been disabled by you as you have taken the G-fan wire off and hijacked it for C wire. The fan switch is merely a non functioning button at this point.
learn some new. thanks
