New Goodman gas furnace flashes six times

I just installed a brand new Goodman 40k BTU 80% downflow furnace and I cannot get any thing to work except six flashes. If I turn the fan to the on position at the thermostat the fan will not kick on with the heat off or on. I replaced the fuse and all I see is open limit switch fault and have no idea how to remedy the situation. I have installed at least 30 units in my life and never had such an issue. I have checked and rechecked all connects at furnace and thermostat totally unhooked everything and slowly reconnected everything and still same issue. Thanks in advance.
