    Goodman furnace - insuring safety is correct
    Had a few good learning steps! Ok so I ended up replacing a bad blower. Now got everything seeming to work correctly but I remember when the blower wasn't running with the bad blower the furnace would cut off into safe mode. I don't remember how long though it took.
    I unplugged the wire for the blower fan for the heat setting to see if this safety feature worked.
    Doesn't seem to. I think I have two wires mabye backwards?
    Where should I start?
    There id one I'm not sure they could be backwards.
    Two red wires that go to the aux lim and says limit switch
    So if this wire are backwards doe the switch stay open/close so the limit doesn't kick in?
    Also how long before the limit switch take to kick in if the blower isn't working?

    It's not possible to wire the limit switch back ward's. Burner's should shut down within say 2 minutes with no fan.
