A furnace repair guy replaced my blower motor, but he got the wiring wrong. Rather than call him back again, I'd rather fix it myself (assuming its just a matter of connecting the right wires). Here's what I see:
The result right now is that the heating system works fine, and the fan works fine. However, the fan shuts off when I switch the system to "Cool" (the outdoor condenser unit starts up and runs just fine).
I'm totally inexperienced in this stuff, but can figure it out when I need to (I replaced the inducer a few months ago). Please let me know if there's any other information needed in order to tell what connections should be made. Thanks!!
