Hey guys. If possible, i'd like to jump out a bad relay, on my Coleman furnace. It's used to switch from HEAT to AC. I don't need the AC, just the HEAT. I don't see where i can insert pics of relay, and schematic, so if someone can help me out here, i'll post them :)

I’m not a HVAC tech, but yes it is possible to jump out a relay, there is a coil that when powered closes or opens contacts. You need to figure out what set of contacts control the AC and disconnect it, and then cap it off so it’s not shorted.

Thanks JP, but that is what i'm not sure of, which is why i'd hoped to be able to post s pic of schematic, then someone with more electrical knowledge than i have, could post exact wiring steps to take. I know yellow wire, from center of rocker switch-to-#3 on relay, is AC, but i'm not sure how to by-pass relay, and still have a working furnace? :)
