Hi, thanks for replying. It is a gas powered 90+ forced air furnace. No one has worked on the stat. When you say check the wires do you mean at the furnace too? I pulled the Y off and the that did stop the central air.

If you pull the Y off at the tstat and it dont run then it could be in the tstat there . Ok now if you want pull W off the tstat, put Y back and you should have only cool.

I cant say that for sure from here . But it sounds like it could be.
Look on the wire schematic there that you have. If the AC runs when you call for heat and dont run when you call for heat and pull Y off it sounds like its in the tstat.
