Wiring power transformer to furnace
Asked Jul 5, 2006, 10:20 PM
I have a lennox furnace & I am trying to replace my transformer. On my old transformer one side has a black wire coming out connecting to a black wire coming out of the furnace. On the same side there is a white wire connecting to a yellow wire on furnace. On the other side there is a red wire coming from transformer connecting to a yellow wire, a green wire coming from transformer connecting to a blue wire. On the new transformer from radio shack one side has 2 black wires and the other 2 yellow & 1 black. Where do I hook these wires up to? Help please...
